Crompton: Waterborne Polyurethane
Crompton Corp.'s Urethanes business has introduced Witcobond W-281F, a 40 percent solid-aliphatic aqueous polyurethane adhesive that exhibits high-cohesive strength while being totally free of organic solvent. It forms strong bonds to many substrates and is an excellent laminating adhesive for PVC to a variety of substrates, as well as for laminating fabrics to TPUs (thermoplastic urethanes). The adhesive is also suitable for formulation in plastic and leather coatings, particularly for post-application embossing. W-281F is compliant with FDA regulations for indirect food contact for coatings and adhesives.
