How is Acrylic Paint Made: Ingredients to Process In Easy Language

Acrylic paint, a popular fast-drying water-based paint, is made up of a synthetic resin binder made from a mixture of acrylic polymer particles, suspended in water and fine colored pigment particles.

This composition is what gives acrylic paint its versatility, durability, stability and vibrant color properties. 

How is Acrylic Paint Made – Composition

The making of acrylic paint is quite simple, the composition of acrylic paint mainly consists of the following elements:

Acrylic Resin

Acrylic resin is the main component of acrylic paint. It is made up of minute particles of plastic acrylic polymer. These particles provide the paint with its binding properties and help it adhere to various surfaces.

Delivery Mechanism (Water)

Acrylic paint is water-based, which means it contains a significant amount of water. The water acts as the solvent and delivery mechanism (also known as a vehicle) that keeps the acrylic resin particles suspended and allows for easy application and manipulation of the paint.

Pigments

Pigments are finely ground particles of dry powder that provide color to the paint. They come in various forms and are mixed with the acrylic resin and water to create the desired color palette. Pigments determine the opacity and vibrancy of the paint.

Additives

Acrylic paint may also contain additives to enhance its performance and characteristics. Additives can include stabilizers to prevent the settling of particles, flow agents to improve the paint’s consistency, and preservatives to prolong its shelf life.

Acrylic Paint Manufacturing Process

The key part of how acrylic paint is made is in the manufacturing process and preparation as you need to know the right materials and for consistent results you need to note the ratios used for each material.

Emulsion Preparation

The first step in creating acrylic paint involves preparing the emulsion. Acrylic resin, in the form of small solid particles, is dispersed in water to form the acrylic polymer emulsion. This emulsion acts as the liquid medium for the paint.

Pigment Incorporation

High-quality pigments are carefully selected and ground into fine particles. These pigment particles are then mixed with the acrylic polymer emulsion, ensuring a thorough and uniform distribution. The amount of pigment used determines the paint’s opacity and intensity.

Stabilization

To prevent the particles from settling, additives called stabilizers are introduced into the paint mixture. Stabilizers ensure that the acrylic resin particles remain evenly dispersed throughout the paint, allowing for consistent color and texture.

Evaporation and Film Formation

When acrylic paint is applied to a surface, the water in the emulsion begins to evaporate. As the water evaporates, the acrylic resin particles gradually fuse together, forming a strong and flexible polymer film. This film adheres to the surface and dries quickly, resulting in a durable and water-resistant finish.

So, you can see how necessary it was for the artists of that time to have access to such a versatile paint.

Influential Acrylic Artists & Art Movements

Here are some influential artists who embraced acrylic paint and helped it gain recognition:

  • David Alfaro Siqueiros – A Mexican muralist, he played a key role in the adoption of acrylic paint. Siqueiros sought a new, more durable paint that would resist the harsh climate in Mexico. He discovered that acrylic paint was the answer to his problem. This discovery played a vital part in popularizing acrylic paint among other Mexican muralists who dealt with similar issues. He was also well known for his acrylic pours which he referred to as ‘accidental painting’.
  • Sam Golden & Leonard Bocour – These two American artists, known for their expertise in paint manufacturing, developed the first artist-grade acrylic paints. They introduced a line of colors that laid the foundation for modern acrylic paint. This bold step widened the scope of possibilities for artists everywhere. Sam was the founder of Golden paints.
  • Abstract Expressionists – The movement of abstract expressionism, which emerged in the 1940s, quickly embraced acrylic paint. Barnett Newman, an influential American artist, was one of the pioneers in this art movement. Artists such as Newman found that acrylic paint allowed them to produce bold and large-scale works with ease.
  • Pop Art Movement – Acrylic paint was also popular among the artists of the Pop Art movement during the 1960s. Iconic artists like Andy Warhol, Roy Lichtenstein, and David Hockney made great use of acrylic paint in their works. This medium allowed them to create striking visuals that captivated the viewer’s attention.

Ingredients and Composition

Acrylic Polymer Emulsion

Acrylic paint begins with a base called acrylic polymer emulsion. This substance is what holds the paint together and gives it its distinct properties.

By creating a water-resistant coating after drying, acrylic paint allows artists to build layers and create unique textures in their artwork.

Plus, it dries much faster than other types of paint, such as oil-based paints. That means you can quickly move onto your next piece or layer without waiting too long.

Pigment Particles

To add color to acrylic paint, pigment particles are combined with the acrylic polymer emulsion. These particles are key to determining the vibrancy and intensity of the acrylic colors you use in your artwork.

Different binders can affect the appearance and properties of the paint. A finely balanced dispersion of pigment within the emulsion of acrylic polymer is necessary to create quality acrylic paint.

This process ensures that the paint has a buttery consistency when you squeeze it from the tube, making it a pleasure to work with in your art projects.

Experimenting with various acrylic colors and pigment particles can lead to a more diverse and visually exciting portfolio.

Plus, it can be fun to see how each pigment interacts with the acrylic polymer emulsion.

Remember that a solid grasp of acrylic polymer emulsion and pigment particles is key to achieving those eye-catching visual effects in your creations.

Acrylic Paint Lightfastness

Many people assume that acrylic paint is lightfast, that is, it does not discolor or fade over time when exposed to light. The reality is that acrylic paint can vary in lightfastness depending on the specific pigments used.

Many high-quality artist-grade acrylic paints are formulated with pigments that exhibit excellent lightfastness, meaning they are resistant to fading and retain their color integrity for long periods. 

These paints are often labeled with a lightfastness rating or a color index (e.g., ASTM or Blue Wool Scale) that indicates their lightfastness level.

However, it’s important to note that not all acrylic paints have the same level of lightfastness. Lower-quality or student-grade paints may contain pigments that are less lightfast and could fade or change color when exposed to light.

To ensure the lightfastness of your acrylic paint, it is advisable to choose artist-grade paints from reputable manufacturers that provide information about the pigments’ lightfastness on the packaging or in product descriptions.

Additionally, protecting your artwork from prolonged exposure to direct sunlight or harsh lighting conditions can help maintain the paint’s color integrity over time.

When working on projects where lightfastness is a concern, such as fine art pieces or works intended for display, it is recommended to use pigments with excellent lightfastness and follow best practices to preserve the longevity of your artwork.

Drying Process and Time

Water Evaporation

Acrylic paint contains water, which makes it easy to apply and spread on surfaces. As you paint, the water in acrylics begins to evaporate, leaving the pigment and acrylic polymer behind on the canvas.

This evaporation process is necessary for the acrylic paint to dry and harden. Although the evaporation time can vary depending on factors like temperature and humidity, a thin layer of acrylic paint typically dries within 10-30 minutes.

You can find that acrylic paint dries faster than oil paint which uses linseed oil as a binding agent and requires much water during the painting process.

Fast Drying Process

One of the main benefits of acrylic paint is its fast-drying properties. When comparing with oil painting, acrylics offer a better painting experience with less waiting time between layers.

This feature allows you to move on with your art project quickly, making it an ideal choice for fast-paced artists or those who prefer not to wait around for their paint to dry.

Remember that the drying process can be influenced by various factors, such as the thickness of the paint layer.

Thicker layers of paint tend to take longer to dry, up to 2 hours or more. Be cautious when applying thick layers to avoid cracking or peeling as the paint dries.

To sum up, acrylic paint’s drying process and time mainly depend on water evaporation, and its fast-drying nature benefits artists who want to keep their creative momentum flowing.

By understanding these drying factors, you can better control your painting experience and achieve the desired effects with ease and precision.

Soft Body Acrylics

Soft Body Acrylics: Soft body acrylics have a creamy consistency that falls between heavy body and fluid acrylics.

They offer good coverage while still being pourable and brushable. Soft body acrylics are versatile and popular among artists who want a balance between viscosity and fluidity.

Fluid Acrylics

Fluid acrylics contain a smaller amount of acrylic binders, so they have a thinner consistency than heavy body acrylics.

They flow easily and can be applied with a brush, spray bottle, or poured directly onto the painting surface. This makes them great for creating smooth washes or intricate details.

Acrylic Gouache

Acrylic gouache offers the best of both worlds, combining the matte finish of traditional gouache with the durability of acrylics.

This type of paint dries flat and has a velvety texture, making it a good choice for illustration work.

Comparisons to Other Painting Mediums

Oil Painting

The difference between acrylic and oil painting lies in their composition and drying time. Acrylic paint is made with synthetic resin binders and dries quickly, allowing artists to layer colors more easily.

On the other hand, oil paint is made from natural oils, like linseed oil, and takes much longer to dry. This slow drying time means blending colors is easier with oils but requires patience.

Oil paintings have a rich history and deeper color saturation, which some artists prefer due to the luminous quality it brings to their work.

Yet, cleaning up after using oil paints can be more challenging, as it requires a solvent like turpentine. Acrylic paint is water-soluble, which makes clean-up a breeze with just soap and water.

Watercolor Painting

Watercolor is another popular medium that has some key differences from acrylic. Watercolor paint is made with pigments suspended in a water-soluble binder, which gives the paintings their characteristic transparency.

Once applied to paper or other surfaces, the water evaporates, leaving behind delicate layers of color.

In contrast, acrylic paint is opaque and more versatile in terms of application. You can achieve a wide range of effects, from thin glazes resembling watercolors to thick impasto techniques similar to oil paints. 

Acrylics can be applied on various surfaces, including canvas, wood, or paper, while watercolors are typically confined to paper.

A necessary aspect to consider when choosing a painting medium is your working style and desired outcomes.

If you like the idea of layering colors, want your art to dry fast, and appreciate effortless clean-up, acrylic painting might be your best option.

But if you’re drawn to the rich, classical appeal of oil paintings or the ethereal transparency of watercolor, those mediums could be the right choice for your artistic journey.

Selecting the Best Acrylics

Factors to Consider

Selecting the perfect acrylic paint depends on a few key aspects. First, focus on the main ingredients such as pigment quality, color strength, and the acrylic binder. Artist grade paints tend to have higher pigment content, providing richer and more vibrant colors.

Don’ts:

Don’t inhale the dry pigments

Avoid inhaling or ingesting pigments as they may contain hazardous materials. Work in a well-ventilated area and take necessary precautions to prevent accidental ingestion. Some pigments such as cadmium or some whites contain carcinogenic compounds that can cause cancer if inhaled or lead which we all know can cause other issues. Once mixed in paint they are harmless unless ingested.

Don’t mix incompatible pigments

Some pigments may react unfavorably when mixed together, resulting in color shifts or instability. Research and avoid mixing pigments that are known to be incompatible. I have a short section below on pigment compatibility if you want to know more.

Don’t use excessive water

While water is used to adjust the consistency of the paint, adding too much water can compromise the paint’s integrity and performance. Add water in small increments to avoid diluting the binder excessively.

Don’t Use Dirty Water or Tap Water

When mixing your own acrylic paint, it is generally recommended to use distilled water rather than tap water. Distilled water is purer and free from impurities that may affect the stability and quality of the paint. Here’s why distilled water is preferred:

  • Elimination of Impurities: Tap water may contain minerals, chlorine, or other impurities that can interfere with the paint’s consistency, drying time, or color. These impurities can potentially affect the paint’s performance and result in unwanted effects such as color shifts or reduced adhesion. Distilled water, on the other hand, is free from such impurities, providing a cleaner and more reliable medium for mixing acrylic paints.
  • Consistency Control: Distilled water has a consistent pH and composition, which helps maintain the desired consistency of the paint when used for dilution. Tap water, on the other hand, can vary in its mineral content and pH, which may introduce unpredictability in the paint’s behavior, such as changes in viscosity or film formation.
  • Preservation of Paint Quality: Using distilled water minimizes the risk of introducing contaminants or impurities into the paint mixture. This helps preserve the quality and longevity of the paint over time, reducing the likelihood of issues such as mold growth or degradation.

Don’t cross-contaminate pigments

Keep your pigments separate and avoid cross-contamination. Clean your tools thoroughly between different pigments to maintain color purity.

Don’t disregard safety precautions

By following these do’s and don’ts, you can create homemade acrylic paint with better results, maintain safety, and enjoy the customization that comes with the process.

Pigment Compatibility

While there are no universal rules about pigment incompatibility, some combinations of pigments are known to have adverse reactions when mixed together.

These reactions can result in color shifts, loss of stability, or other undesirable effects. Here are a few examples of pigments that are generally considered incompatible when mixed:

Cadmium Yellow and Phthalo Blue

Mixing cadmium yellow, a lead-based pigment, with phthalo blue, a copper-based pigment, can lead to an undesirable greenish hue and potential color changes over time.

Ultramarine Blue and Hansa Yellow

 Ultramarine blue, a sodium-based pigment, and Hansa yellow, an arylide pigment, can create a muddy or brownish mixture due to the interaction between these pigments.

Chrome Green and Quinacridone Magenta

Chrome green, a chromium-based pigment, and quinacridone magenta, a synthetic organic pigment, can result in a brownish mixture due to the chemical reactions between the two.

Zinc White and Earth Colors

Mixing zinc white, which has a lower opacity, with earth colors like raw sienna or burnt umber can cause the white pigment to lose its covering power, resulting in a less opaque mixture.

These are just a few examples, and other pigment combinations may be considered incompatible.

It’s important to note that pigment formulations can vary across manufacturers, so it’s always a good practice to consult pigment manufacturers’ guidelines or conduct small test mixtures to observe any potential compatibility issues.

If you’re unsure about specific pigment combinations, it’s recommended to consult pigment manufacturers or reference resources like color charts or pigment compatibility guides to ensure compatibility and avoid undesired reactions when mixing pigments.

Oil Paint Pigments and Acrylic Paint Pigment Compatibility

I have always been told it is best to avoid mixing pigments specifically formulated for oil paints with pigments intended for acrylic paints.

While some pigments may be compatible across different paint mediums, there are significant differences between oil and acrylic paints that can affect the performance and stability of the mixed pigments.

Here’s why it is generally not recommended to mix oil paint pigments with acrylic paint pigments:

Binder Compatibility

Oil paints use oil-based binders (typically linseed oil), while acrylic paints use water-based acrylic polymer emulsion as binders.

These binders have different chemical properties, drying times, and interactions with pigments. Mixing pigments formulated for different binders can result in issues such as poor adhesion, cracking, or instability.

Drying Time

Oil paints have a slower drying time compared to acrylic paints, which dry relatively quickly. Mixing pigments formulated for different drying times can lead to inconsistencies in the paint film, affecting the overall quality and appearance of the artwork.

Pigment Particle Size

Pigment particle sizes can vary between oil and acrylic paints. Incompatibilities in particle sizes can affect color mixing and the texture of the paint film. For instance, oil paint pigments may have larger particles, which can lead to a gritty texture if mixed with smaller particles in acrylic paints.

Film Flexibility

Oil paint films have greater flexibility compared to acrylic paint films. Mixing pigments formulated for different levels of flexibility can result in cracking or flaking over time.

It’s important to note that some pigments can be used in oil and acrylic paints without significant issues.

However, it is advisable to consult pigment manufacturers’ guidelines or conduct small test mixtures to assess compatibility and performance before mixing pigments from different paint systems.

To ensure the best results and maintain the desired characteristics of your paints, it’s generally recommended to use pigments specifically formulated for the paint medium you are working with (i.e., oil pigments for oil paints and acrylic pigments for acrylic paints)
