With competitive price and timely delivery, CHENGYU sincerely hope to be your supplier and partner.

Pigment pastes used in epoxy resin have a relatively thicker consistency that blends well with the mixture. A little goes a long way for this paste colouring agent to build your resin colour strength. These coloured, dry, and pure pigments can also be blended with other colours so you can produce new ones. Pigment pastes for resin colouring are non-solvent and free-flowing.

Dispersed pigments in epoxy resin blends react into the system, so there are no changes to its properties when cured. These colours can be translucent or opaque. It all depends on the pigment used, how much you add, the thickness of the film, and substrate colour. You can blend paste colours up to 10% of the total epoxy resin mixture, given their intense concentration.

Pigment pastes might have many good characteristics that’s why you should also know why epoxy pastes are better for resin. This article will also teach you how to use pigment pastes in resin and why not to use acrylic paints to colour resin.

Liquid, Powdered, or Paste Pigments: Which is the Best?

You can use liquid, powdered, or paste pigment for your resin art, but the three types have differences.

Liquid pigments can come in liquid resin colourant or alcohol inks. As the name suggests, this resin pigment colourant is in liquid form. It can be mixed and matched to create various colours and shades. Resin artists use them for colour tinting.

On the other hand, powdered colourants can be mica powder or pigment powder. Mica powder blends with varnish that can produce a sparkly effect. Also, powdered pigments usually produce a matte finish and have a bit of sparkle effect.

The third type is paste pigment, a unique texture in a paste consistency. There's a reason why epoxy pastes are better for resin. Pigment pastes are ideal for high colour saturation projects with rich concentration and solid colour effects.

Advantages of Pigment Paste & Why Epoxy Pastes are Better for Resin

Epoxy pastes are better for resin for the following reasons:

● Environmentally friendly because they are solvent-free and have very low Volatile Organic Compounds (VOC)

● Easy to use by simply stirring to the resin

● Have high chroma and brightness

● Produce a glossy finish

● Have broad compatibility

● Have fine dispersion

How to Use Pigment Paste to Colour Resin

Now that you're acquainted with the many wonders of epoxy pastes and why they are better for resin, it's time to learn how you can use them in your next DIY project.

Here's a step-by-step guide on how to use pigment paste in resin:

1. Prepare all the necessary materials beforehand.

Resin can cure very quickly when applied, making time a crucial factor when working with epoxy. Make sure your environment is ready before you dive into your project.

2. Create an anti-splash workspace.

You can protect your work from any potential contaminants by covering the area with plastic sheeting.

3. Wear your protective gear.

Your health and safety are still the highest priority in the room. So, make sure to wear personal protective equipment (PPE).

4. Mix the resin and hardener.

Carefully blend the ingredients compliant to the recommended mixing ratio.

5. Add the pigment paste.

After mixing the epoxy and hardener together, you can now add the pigment paste to the mixture. Apply paste depending on your desired level of concentration, then mix well. The more you add, the deeper its pigmentation becomes. You can repeat this process until you're able to bring out your desired shade.

6. Maintain the proportion of your paste below 10%.

Otherwise, you might affect the mixing ratio in a way that impairs the hardening process.

Pigment Paste Uses: Tips and Tricks

Different colour medium changes the mixing ratio between resin and hardener. When unaddressed, it can lead to sudden issues. You can avoid this dilemma by considering these tips and tricks for using pigment pastes.

● To maintain the minimal change to the mixing ratio, choose highly concentrated or highly pigmented colours.

● To test the colour against its reaction with the resin, mix a small amount of the two components first to observe the result.

● To efficiently estimate the reaction between the uncoloured resin and the coloured resin, try to get a feel of the properties of pure epoxy first. Gaining this knowledge will help in future measurements.

● To avoid unfortunate effects on the resin-hardener mixing ratio, try not to use paints that contain high amounts of water.

● To minimize the visibility of yellowing resin over time, choose an adequately lightfast colour. It will ensure that the fading colour from UV radiation will be hardly noticeable, unlike with coloured resin.

Whether you're using paste pigment or powdered colour, your end product will still depend mainly on the basic texture of your epoxy. Various compositions may have different reactions to different colourants. That's why it's essential to ensure the quality of the resin art supplies that you're using.

Another factor to consider is the archivability of your colouring material. 'Archivability' is the durability of the ink or pigment, which can be determined by its water resistance, pH neutrality, and lightfastness.

When you're looking at the lightfastness of the artwork, you will want to see how well the pigment fulfils upon light exposure, regardless of the source. Direct sunlight might be the most damaging variant, but fluorescent and halogen lights harm inks, too. Meanwhile, incandescent lights hold minimal taint to ink and most artworks. It's also the reason why they are the conventional gallery lights.

The most lightfast are acrylic ink, mica and pigment powder, while the most sensitive are dyes.

Read on to know more if your art pieces can stand the test of time. Here are the different colouring materials you can use on your resin art and how they perform time-wise.

● Acrylic Ink

Due to the molecular bond of the colour and plastic, acrylic ink has the highest lightfastness and most extended lifespan among other inks. It's also waterproof and pH-neutral or acid-free.

● Mica and Pigment Powders

Both talc colours are immune to acid, alkali, heat, light, and weather. They are non-conductive and easy to disperse, thanks to the stability of their chemical properties.

Pigment powder looks similar to pulverized coloured chalk. It comes in many forms once mixed in with binders with which most pigment pastes are made. Usually, powdered colours take the name of their actual colours. While they don't shimmer the way mica powder does, they are outstanding colouring elements.

● Craft Paint

Due to its numerous water-based binders, craft paint is subject to a relatively faster fade time. Hence, it can't be considered archival.

● Alcohol Ink

This dye-based variation can have a wonderful output, however, it's not as stable when exposed to light. Alcohol ink pigments dissolve in Isopropyl or Ethyl alcohol and a binder, making the granules small and translucent.

● Dye-based Ink

This product comes from a mixture of water-soluble dyes and gum arabic, creating a wide range of colours and brilliance. Dye-based colours can be dazzling bright due to their low lightfast rating. Because it needs to avoid excessive light exposure, dye-based coloured pieces ideally stay within portfolios and sketchbooks.

Pigments You Shouldn't Use on Resin

● Acrylic Paint

As mentioned above, there is a good reason as to why you shouldn’t use acrylic paint to colour resin. Usually mixed with water, colour pigments, and binding agents, acrylic paint also blends with additives (i.e. preservatives). These elements are vulnerable to unpredictability, especially when combined with epoxy resin. Also, acrylic paint produces a matte and striped finish when used on flat surfaces.

● Oil Paint

The lipids usually found in oil paints pose challenges in smoothly mixing the pigment with resin. When used for resin projects, it will only form lumps that you can't mix.

● Watercolour

This type of paint is not suitable for blending with epoxy resin simply due to its weak pigmentation.

The use of Epoxy Resin in art and crafts projects has dramatically impacted creative communities worldwide. As this popular medium is crystal clear, adding color and special effects is essential in most applications and there are two popular options to color epoxy resin: resin pigment paste and pigment powders. In this article we'll delve into the differences between these added colorants to help you make an informed choice for your project. Additionally, we'll provide a step-by-step guide on how to make your own pigment paste for resin art. So keep reading!

What is Resin Pigment Paste?

Pigment paste for Epoxy Resin is a thick colorant in paste form, generally made of pigment powder and Resin Part A, making it heavier than pigment powders. As resin part A is one of the components, it is easy to mix into Epoxy. The thicker consistency ensures great control over the amount needed to get the desired color intensity, and as we just mentioned, it allows for superb blending. A little bit provides a fairly high opacity level.

In this section, we'll explore the benefits of using resin pigment paste and highlight its key features.

Vibrant and Opulent Color

Pigment Pastes for Epoxy are renowned for producing vibrant colors in resin art pieces. This effect is caused by the concentrated pigments in the paste formulation, which creates intense hues that remain true even after the resin cures, resulting in stunning and eye-catching artwork.

Great for Resin Waves

White Resin Pigment Paste is a favorite of ocean artists, offering several advantages when making frothy resin waves or sought-after cells and movement in ocean art pieces due to the heaviness of this resin colorant. When poured on top of clear resin layer the white colored resin sink allowing the clear to float to the top. If you want to learn more about this technique check this blog article describing how to make stunning resin waves.

How to Make Pigment Paste?

Now that we've explored the differences between resin pigment paste and pigment powder, let's dive into making your own white pigment paste for resin art and more specifically, for resin waves.

Gather the Materials

To create a white pigment paste for resin ocean art, you will need the following materials:

• White Pigment Powder
• Epoxy Resin (Part A)
• Glass mixing surface
• Palette Knife
• Container with lid

Mixing the Pigment Paste

Start by wearing a protective mask to avoid inhaling any pigment particles. In a clean glass mixing surface, combine both ingredients in 3:1 ratio. Measure 3 parts of white pigment powder and 1 part of Resin Part A. Mix thoroughly until a smooth and consistent paste is achieved.

Storage and Application

Transfer the pigment paste into a sealable container for storage. To color your resin project, add a fingernail amount of the paste per ounce of epoxy resin and stir until fully incorporated. Then the mixture is ready to pour and make waves.

What is Resin Pigment Powder?

Pigment powders are also popular options for coloring resin projects, and they offer unique advantages that may appeal to different artists and crafters depending on the intended results. For example, woodworkers prefer the stunning movement and special effects pigment powders create in deep pours and river tables.

Pigment Powders are mostly made of natural minerals, true metals, and some even from synthetic materials. For your reference, we have listed below the most popular epoxy pigment powders you can use to color your resin projects.

Mica Powders

Mica powders are the preferred type of pigment powders for epoxy resin. They have a pearlescent, shimmery finish that adds depth and motion to the cured resin layers. Micas are made by grinding that natural mineral into powder form resulting in non-toxic and inert dazzling pigments. They don't dissolve into the Resin, so the particles remain suspended, and when exposed to light, they provide a beautiful sparkling finish.

True Metallic Pigments

Unlike micas, true metallic pigments' golden or silvery appearance comes from real metals like Aluminum, Copper, and Zinc powder. They have a smaller particle size than micas, making them float to create stunning special effects in resin art pieces. In addition, you only need a small amount to color epoxy resin.

Glitters

Glitter is primarily made of synthetic materials like PET (Polyethylene Terephthalate) and cut into specific shapes and sizes to create a shiny effect in your resin art projects. Additionally, plastic-free options are available, such as our Dazzling Diamond, which uses synthetic micas with Synthetic fluorphlogopite as its main component. It is essential to understand that glitter does not add color to the medium; the tiny or chunky particles will remain suspended in a translucent resin. To achieve a more saturated result, add more glitter. However, if you prefer a sparkling but see-through finish, adding a small amount of glitter to the layer of Resin being poured is recommended.

Versatility and Customization

Artists can blend different pigments using pigment powder to create customized colors. This flexibility provides unlimited options and enables them to match specific color palettes or try out unique DIY shades.

Translucency and Layering

Pigment powders are often preferred for achieving translucent effects in resin art. By layering multiple coats of colored Resin, artists can create stunning depth and dimension in their artwork, resulting in a mesmerizing visual experience.

Cost-Effectiveness

Compared to resin pigment paste, pigment powders generally offer a more cost-effective solution for resin art enthusiasts. A little goes a long way, as small amounts of pigment powder can create vibrant colors, making it an economical choice, especially for large-scale projects. On top of that, you can make your own DIY pigment paste out of pigment powder and resin Part A, as you have seen in the tutorial above.

Conclusion

When coloring your resin art project, there are a couple of options: resin pigment pastes or pigment powders in any of the main three variants, mica powders, metallics, or glitters. Each colorant has its benefits depending on your artistic preferences and project needs. We always recommend trying various techniques, colors, and mediums to fully understand resin art's potential. Knowing the difference between resin pigment paste and pigment powder will enable you to create stunning resin artworks.
