K-FLEX XM-337 is designed for VOC-compliant, 2-component polyurethanes and melamine baking systems with improved flexibility, hardness and toughness.
The high Tg provides the hardness of an aromatic polyester but with light stability. Despite its’ high viscosity (55,000 cP) it reduces efficiently to a spray viscosity at 85% solids with MIBK or n-butyl acetate.
