WITCOFLEX 974

WITCOFLEX 974 is a solvent-based polyurethane solution formulated in Methyl Ethyl Ketone, characterized by its pale straw appearance. This product is specifically designed for coating lightweight textiles, including woven or knitted nylon, polyester, polycotton, and non-woven substrates. Witcoflex 974 is typically applied as a base coat or tie-coat using direct or transfer coating methods. The coatings formed with Witcoflex 974 exhibit both water resistance and water vapor permeability, making them ideal for manufacturing breathable coated fabrics. Unlike traditional microporous coatings, the Witcoflex system allows water vapor to pass through a continuous non-porous film, resulting in a highly waterproof, windproof, and durable membrane.
