Createx Colors 4030 Intercoat Mix Additive – 8oz

Meet Createx Colors 4030 Intercoat, a water-soluble polyurethane clear designed to blend with any Createx Colors paint. When mixed, it helps the paint flow more evenly, reduces surface tension, and encourages a smooth, balanced laydown across edges and contours. The result is a clearer, more uniform film that stays true to your base colors while adding a layer of protection as it dries.

Designed as both a flow enhancer and adhesion promoter, 4030 Intercoat supports heavier applications without cratering and can improve bonding to common substrates like plastics, models, vinyl, rubber, and resin kits. It creates an acrylic-urethane balance that strengthens the coating after air drying, bringing improved scratch resistance compared with air drying alone—without changing the color you’ve laid down.

Key details to know before you spray or brush: it is water-based, meets ASTM D-4236, and is proudly made in the U.S.A. You can mix 4030 Intercoat into Createx Colors paints in any ratio from 10% to 30% by volume, depending on your project goals and spray conditions. It remains compatible with Auto Air Colors, Createx Airbrush Colors, Wicked Colors, and Createx Illustration Colors, making it a versatile addition to many color sets.
