Slow reacting, dual-component polyurethane resin



WILLPUR® WX is a slow reacting CFC and halogen free two component injection resin. Without water contact, the product cures to a high-strength, non-foamed polyurethane resin. When the injecting product comes into contact with water, it becomes a compact, solid foam with a clear acceleration of the final reaction.
