Colorkast White Pigment is the essential, professional-grade "paste-style" resin colorant for every glassing bay. White is the most frequently used color in surfboard manufacturing, used for everything from classic opaque "white-outs" to creating custom pastel tints. Unlike standard liquid dyes that can yellow or lose their brightness over time, Colorkast’s high-quality paste formula is engineered for maximum opacity and UV stability, ensuring a crisp, clean finish that stays white for the life of the board.

This colorant is highly adaptable for any custom build: depending on the "color-load" added to your resin, you can achieve a soft transparent tint or a solid, high-density opaque pigment. As an Opaque Pigment, it provides a bold, non-transparent finish that is the industry standard for masking foam imperfections, covering "shaper's marks," or creating a clean canvas for top-coat artwork. When used in smaller amounts, it creates a "milky" transparent effect often used in vintage-style laminations.

Colorkast paste-style colorants are highly concentrated and disperse quickly in both polyester and epoxy resins, ensuring a streak-free, professional finish in the glassing bay.

Key Features:

Paste-Style Formula: Superior pigment concentration for maximum "hide" and resistance to UV yellowing.

Pure White Palette: Delivers a bright, clean White that stays true even in harsh marine environments.

Variable Transparency: Effortlessly transition from a "milky" translucent tint to a deep, solid opaque pigment.

Professional Consistency: Formulated specifically for the surfboard industry to ensure a perfect resin cure and high-gloss finish.

Essential Mixing Base: The primary ingredient for mixing with other Colorkast colors to create custom pastels and muted tones.

Pro Tip: To achieve a perfectly flat "White-Out" opaque finish, ensure your lamination is pulled tight to the foam. Because white reflects light, any variation in resin thickness or "pools" will be less visible than with darker colors, but a tight pull is still essential for a lightweight, professional-strength board.
