Ever wondered how to transform plain epoxy resin into stunning, colorful art? The secret lies in using the right pigment. Understanding epoxy resin and its interaction with pigments is crucial for achieving vibrant results. In this post, you'll learn how to select and add pigments to epoxy resin, enhancing your projects with dazzling colors.
When it comes to adding color to epoxy resin, selecting the right type of pigment is crucial for achieving your desired look and ensuring the resin cures properly. There are mainly two types of pigments used for epoxy tinting: liquid pigments and powder pigments. Each has its unique characteristics and applications.
Liquid Pigments: These are resin pigment liquids or epoxy resin liquid pigments that blend smoothly into the epoxy resin. They provide even, consistent color and are excellent for creating transparent or translucent effects. Liquid epoxy pigments are easy to dose, allowing precise control over color intensity. However, adding too much liquid pigment can affect the curing process, so it’s recommended to keep the pigment ratio below 5% of the total resin volume.
Powder Pigments: Powder pigments, such as mica powders or resin color pigments, offer vibrant, opaque colors and often add a shimmering or pearlescent effect. They are ideal for bold, solid colors or creative effects like swirls and patterns. Since powder pigments do not contain solvents, they generally have less impact on the resin’s curing. However, they require thorough mixing to avoid clumps and settling.
Desired Opacity: If you want a translucent tint, liquid epoxy resin dyes or liquid pigments are the best choice. For opaque or shimmering finishes, powder pigments work better.
Color Intensity Control: Liquid pigments allow gradual tinting by adding small amounts, while powder pigments can quickly intensify color with less volume.
Compatibility: Not all pigments are compatible with every epoxy resin. Always check the manufacturer's recommendations to avoid curing issues.
Effect and Finish: Consider if you want a smooth, uniform color or textured, sparkling effects. Powder pigments can add depth and texture, while liquid pigments provide a smooth finish.
Safety and Quality: Use high-quality pigments designed specifically for epoxy resin. Low-quality pigments may contain fillers that affect color stability and resin performance.
Several brands specialize in epoxy resin color pigments and dyes, known for their reliability and vibrant colors:

Choosing reputable brands ensures your epoxy tinting projects have vibrant, lasting colors without compromising resin quality.
Tip: Always start by adding a small amount of pigment—whether liquid epoxy pigment or powder—to your resin mixture and gradually increase until you achieve the desired color intensity without affecting curing.
Before you start adding pigment to epoxy resin, proper preparation is essential for a smooth tinting process and a flawless finish. This stage involves mixing the epoxy resin components correctly, taking safety precautions, and gathering the right tools and materials.
Epoxy resin typically comes in two parts: the resin and the hardener. To prepare your base for adding resin pigment or epoxy resin dye, you must mix these components in the ratio specified by the manufacturer. Common ratios include 1:1 or 2:1 by volume or weight, depending on the product.
Measure Precisely: Use a digital scale or measuring cups with clear markings to ensure accuracy.
Combine Slowly: Pour the hardener into the resin or vice versa slowly to avoid introducing air bubbles.
Mix Thoroughly: Stir the mixture gently but thoroughly for at least 2-3 minutes, scraping the sides and bottom of your mixing container. Proper mixing ensures the resin cures evenly and avoids sticky or soft spots.
Once mixed, your epoxy resin is ready for tinting with your choice of resin color pigment, whether powder or liquid.
Working with epoxy resin and pigments requires attention to safety to protect your health:
Wear Gloves: Use nitrile gloves to avoid skin contact with uncured resin or pigments.
Eye Protection: Safety goggles help prevent accidental splashes into your eyes.
Ventilation: Work in a well-ventilated area or use a respirator mask to avoid inhaling fumes.
Avoid Excess Pigment: Adding too much pigment or epoxy resin pigment liquid can interfere with curing and cause skin irritation.
Following these precautions ensures a safer working environment during epoxy tinting.
Gathering the correct tools before starting helps maintain workflow and quality:
Mixing Containers: Use disposable or dedicated cups marked with volume measurements.
Stirring Sticks: Wooden or plastic sticks work well for thorough mixing.
Measuring Scale or Cups: For precise measurement of resin, hardener, and pigment.
Pigments: Choose your preferred epoxy pigment type—liquid epoxy pigment or powder resin color pigment.
Protective Gear: Gloves, goggles, and a respirator mask.
Spatula or Palette Knife: To help mix pigments evenly into the resin.
Having these materials ready simplifies the process of adding color to epoxy.
Adding pigment to epoxy resin is an exciting way to customize your projects. Whether you use powder pigments or liquid epoxy resin pigment dyes, following the right steps ensures vibrant, smooth, and well-cured results. Here’s how to add color to epoxy resin effectively.
Prepare Your Resin MixtureMix the epoxy resin and hardener thoroughly according to the manufacturer’s instructions. Ensure there are no bubbles or unmixed parts.
Add Powder PigmentSprinkle a small amount of resin color pigment powder (such as mica powder) into the mixed resin. Start with about 1 gram per 8 ounces of resin. Powder pigments provide rich, opaque colors and often add shimmer.
Mix ThoroughlyUse a spatula or stirring stick to blend the powder into the resin. Stir gently but completely to avoid clumps and ensure an even color distribution.
Adjust Color IntensityAdd more powder pigment gradually if you want a deeper or more opaque color. Remember, too much powder can thicken the resin and affect curing.
Mix Resin and Hardener FirstCombine the epoxy resin and hardener as per instructions. Mixing before adding pigment prevents curing issues.
Add Liquid Epoxy PigmentPour a few drops of liquid epoxy pigment or epoxy resin dye into the mixture. Liquid pigments are perfect for translucent or even color tones.
Blend WellStir the mixture gently to integrate the liquid pigment fully. Avoid vigorous stirring to reduce air bubbles.
Control Color DepthStart with a small amount of liquid pigment—usually less than 5% of the total resin volume. Increase gradually to reach your desired tint. Excess liquid pigment can interfere with curing.
Start Small: Always add pigment little by little.
Test Samples: Pour a small test batch to check color before committing.
Balance Opacity and Transparency: Powder pigments tend to be more opaque; liquid pigments offer translucency.
Consider Resin Volume: The pigment amount should be proportional to your resin batch.
Adding Pigment Before Mixing Resin and Hardener: This can cause uneven curing.
Using Too Much Pigment: Overloading resin pigment liquid or powder can prevent proper curing or cause brittleness.
Insufficient Mixing: Clumps or uneven color result from poor stirring.
Ignoring Safety: Always wear gloves and work in a ventilated area.
For Swirls and Patterns: Mix different colors in separate batches and pour simultaneously.

When working with epoxy resin color pigment, even experienced users can encounter some challenges. Troubleshooting these common issues ensures your projects come out vibrant and flawless every time.
One frequent issue is color fading after curing, especially when exposed to sunlight or UV rays. Some epoxy pigments and dyes are more prone to fading due to their chemical composition. For example, certain liquid epoxy pigment dyes or resin color pigment powders may lose vibrancy over time if not UV-resistant.
How to prevent fading:
Use high-quality, UV-resistant epoxy pigment brands designed for long-lasting color.
Apply a UV-resistant topcoat or clear epoxy layer to protect the colored resin.
Avoid prolonged exposure to direct sunlight on finished pieces.
If you notice unexpected color shifts, especially with UV resin coloring, it could indicate pigment incompatibility or insufficient UV protection.
Surface imperfections like bubbles, specks, or uneven coloration can detract from your epoxy resin finish. These flaws often result from improper pigment mixing, environmental factors, or incompatible pigments.
Common causes and fixes:
Bubbles: Stir the epoxy resin and pigment gently to minimize air introduction. Use a heat gun or torch carefully to release trapped bubbles before curing.
Specks or clumps: Powder pigments must be fully dispersed in the resin. Sift powders before adding and mix thoroughly. Liquid epoxy pigment blends more smoothly but still requires proper stirring.
Uneven color: Ensure the resin and hardener are mixed evenly before adding pigment. Inadequate mixing can cause streaks or color patches.
Pigment settling occurs when powder pigments sink to the bottom of the resin during curing, leading to uneven color distribution. This is common with heavier mica powders or dense resin color pigment powders.
Tips to avoid settling:
Use finely milled powder pigments for better suspension.
Stir the pigment into the epoxy resin thoroughly but gently.
Pour the resin promptly after mixing to prevent settling.
For large pours, consider multiple thin layers rather than a single thick pour.
Some liquid epoxy pigment formulas are less prone to settling, making them ideal for smooth, even color.
Tip: To maintain color stability and a flawless finish, always choose UV-resistant pigments, mix thoroughly, and pour your pigmented epoxy resin promptly to avoid settling and surface defects.
Choosing the right color pigment for epoxy resin involves understanding liquid and powder pigments, their effects, and curing compatibility.
