Powder Pigments and Mica Powders

Powder pigments offer opacity and intense color payoff. Mica powders, a popular type of powder pigment, create metallic, pearlescent, and shimmer effects that catch the light beautifully.

Benefits:

• Creates opaque or semi-opaque finishes
• Produces metallic, pearl, and shimmer effects
• A little goes a long way
• Excellent for creating depth and dimension

Alcohol Inks

Alcohol inks are vibrant, fluid colorants that create unique effects in resin. They're perfect for creating cells, marbling effects, and organic-looking color movements.

Benefits:

• Creates fluid, organic color patterns
• Excellent for creating cells and marbling
• Highly concentrated
• Provides transparent, vivid color

Other Colorant Options

Acrylic Paint

Can be used in small amounts (less than 10% of your resin mixture) though be aware that even at these small percentages, acrylic paint can potentially affect cure time, final hardness, and long-term durability of your project

Food Coloring

Not generally recommended for epoxy projects as it's water-based, which can interfere with the curing process and cause significant color fading and degradation over a short period of time

Oil-Based Colorants

Limited compatibility with resin systems

Glitter and Pigment Powders

Glitter and pigment powders add sparkle and special effects

How to Choose the Right Dye for Your Epoxy Project

Selecting the perfect colorant can make or break your resin masterpiece, so understanding your options is essential for achieving professional results.

Transparent vs. Opaque: Which Do You Need?

The transparency level you need depends on your project goals:

• Transparent Dyes: Perfect for creating jewel-like clarity, layered effects, and pieces where light transmission is important (river tables, jewelry, coasters)
• Opaque Pigments: Ideal when you want a solid color with no light passing through (countertops, art pieces, solid-colored items)

Color Stability and UV Resistance

Not all colorants offer the same stability. For projects that will be exposed to sunlight, choose dyes specifically labeled as UV-resistant to prevent yellowing and fading over time.

Compatibility with Your Resin

Different resin brands may react differently with various colorants. Always check manufacturer recommendations or test a small batch before committing to a large project.

How to Use Dyes with Epoxy Resin Properly

Mastering the techniques of coloring epoxy resin will elevate your projects from basic to breathtaking, ensuring vibrant, consistent results every time.

Perfect Mixing Ratios

For most liquid dyes, start with just 1-2 drops per ounce of mixed resin. For powders, start with a tiny amount (⅛ teaspoon or less per 8 oz of resin) and gradually increase until you achieve your desired color intensity.

Always mix colorants into Part A (the resin) before adding Part B (the hardener) to ensure thorough distribution.

Preventing Color Separation

To prevent color separation:

1. Mix thoroughly but gently to avoid introducing air bubbles
2. Use colorants specifically designed for resin
3. Don't exceed the recommended amount of colorant
4. Ensure your resin is properly mixed before adding color

Creating Special Effects with Multiple Colors

For multi-color effects:

1. Prepare separate batches of colored resin
2. Pour in layers, allowing each to partially set before adding the next
3. Use toothpicks or stir sticks to swirl colors together
4. Try the "dirty pour" technique where multiple colors are poured simultaneously

Creating Special Effects with Epoxy Dyes

The unique properties of different colorants allow you to achieve professional artistic effects that make your resin pieces truly distinctive.

 

Translucent Depth Effects

Layer different intensities of the same color to create stunning depth. Start with a darker shade at the bottom and gradually lighten as you build layers.

Metallic and Pearl Finishes

Combine mica powders with clear resin to create beautiful metallic effects. For the best results:

1. Mix mica powder with a small amount of resin first
2. Gradually add this concentrated mixture to your main batch
3. Stir gently to maintain the reflective properties

Cells and Organic Patterns

Use alcohol inks or silicone oil with different colored resins to create cell patterns:

1. Pour various colors into your resin piece
2. Add a drop of silicone oil or alcohol
3. Use a heat gun to activate cell formation

Troubleshooting Colored Epoxy Resin Problems

Even experienced artists encounter challenges with colored resin, but understanding common issues helps you quickly identify and resolve problems.

Fading Colors

If your colors are fading over time, you may be:

• Using non-UV resistant colorants
• Exposing your project to too much sunlight
• Using colorants not designed for resin

Solution: Use high-quality, UV-resistant resin dyes and consider applying a UV-protective topcoat.

Streaky or Uneven Coloring

Streaking usually happens when:

• The colorant isn't fully incorporated
• The resin and hardener aren't properly mixed
• Too much colorant is added

Solution: Mix thoroughly but gently, and follow recommended colorant ratios.

Keeping Additives Suspended

When using glitter, mica, or other particles that might sink:

1. Wait until the resin reaches a slightly thicker consistency before adding
2. Mix in small batches and pour when the resin is at a honey-like stage
3. Consider using a resin with a faster cure time

Safety Considerations When Using Epoxy Dyes

The beauty of your creations should never come at the cost of your health, making proper safety protocols essential for every resin artist.

 

Ventilation and Protection

Always work in a well-ventilated area when using resin and dyes. Some colorants may contain additives that release fumes when mixed with resin.

Handling and Storage

• Wear gloves when handling dyes to prevent skin staining
• Store colorants in airtight containers away from direct sunlight
• Keep powders sealed to prevent moisture absorption and clumping

Frequently Asked Questions

What happens if you pour resin too thick?

Pouring resin too thick can cause excessive heat buildup during curing, leading to cracking, bubbling, or yellowing of your project. The resin may not cure properly throughout, resulting in soft spots or a tacky surface that never fully hardens. To avoid these issues, follow manufacturer guidelines for maximum pour depths (typically 1/4" to 1/2" per layer) and allow each layer to partially cure before adding the next.

What is the strongest resin for molds?

Polyurethane resin is generally considered the strongest option for creating durable molds, offering excellent tear resistance and flexibility. Epoxy resin provides superior hardness and chemical resistance, making it ideal for molds that need to withstand repeated use with minimal degradation. Silicone rubber, while technically not a resin, creates highly durable molds with excellent flexibility and release properties for casting intricate details.

How do you make resin molds last longer?

Apply a release agent before each use to prevent resin from bonding to your mold and causing damage during demolding. Clean molds thoroughly after each use with mild soap and water, avoiding harsh chemicals that can break down the mold material. Store molds in a cool, dry place away from direct sunlight and extreme temperatures to prevent warping, discoloration, or degradation of the material.

What is the most popular resin color?

Clear blue oceanic tones consistently rank as the most popular resin colors, particularly for creating beach-inspired pieces and water effects. Metallic gold, silver, and copper pigments are extremely popular choices for adding luxurious shimmer to resin art and jewelry pieces. White and black remain classic favorites for their versatility, with white allowing for light diffusion effects and black creating dramatic contrast in mixed-media projects.
