Description

L-1256 is a high-solids, high-hydroxyl acrylic copolymer that, when combined with non-yellowing polyisocyanates at room temperature, forms a two-component system with excellent application properties, high film build, and outstanding compatibility. It is particularly suitable for high-gloss one-coat black PU coatings and clearcoat formulations. The system offers ultra-fast drying, allowing polishing after 30 minutes at 50 °C.
