Polyester resin can take on a wide range of vivid shades and special effects with the right choice of pigments. Using pigments designed for resin ensures your creative projects look their best and remain stable over time.
Powder Pigments: Versatile and Bold
Powder pigments formulated for resin provide bright, consistent colour throughout your casting or coating. Options like “Neon” Bright Powder Pigments deliver striking hues, perfect for DIY, jewellery, and decorative purposes. To achieve even dispersion, blend pigment into Part A of your resin before mixing in hardener. This approach helps you avoid clumps and get the most vibrant results possible.
Pearlescent and Special Effect Pigments
Mica-based pearlescent pigments such as “Iridron” Pearline Pigments add luxurious shimmer and unique chromatic effects to transparent polyester resins. These pigments come in a variety of colours and maintain their brilliance under light and heat, making them excellent for art pieces, glazing, or decorative surfaces. For something more eye-catching, photoluminescent options like phosphorescent glow-in-the-dark pigments let you highlight details or add creative accents that are visible in low light.
Additives for Special Resin Effects
Alongside colour pigments, consider effect-specific additives that alter your resin’s appearance. For example, cell-effect additives can introduce blooming patterns into pigmented resin for impressive results. These should always be chosen specifically for use with casting resins to ensure compatibility and the intended appearance.
When This Matters
Selecting the right type of pigment becomes crucial if your project demands specific visual effects, high colour intensity, or long-lasting results. Always confirm that chosen pigments or additives are clearly specified for polyester resin use to ensure best performance and finish.
