Curing Agent W3 Polyisocyanate Ichemco Polyurethane (PU) - Isocyanates General Industrial /Maintenance Emulsifiable in water CURING AGENT W3 is a liquid polyisocyanate, emulsifiable in water. Acrylic and PU dispersion polymers can be efficiently cross-linked with this product. An increased resistance against heat, water, plasticizers and many organic solvents can be achieved with addition of 0,5 - 1.8% of CURING AGENT W3 to water compounds. This is very useful for many applications, like industrial coatings, adhesives, textile and leather finishing, etc Liquid polyisocyanate. Used as a crosslinker for acrylic and PU dispersion polymers in industrial coatings. Increases heat, water, plasticizer and many organic solvents resistance. <br> Use level: 0,5-1.8%.
