Curing Agent D Diisocyanate Ichemco Crosslinking / Coupling / Curing Agents >> Diisocyanates Chlorinated Rubber Polyurethane toluene CURING AGENT D is a diisocyanate in solution, designed to cross-link polyols (polyethers and polyesters), polyurethanes and elastomers ( natural rubber, chloroprene, etc.). It cross-links polymers/elastomers used as coatings, increasing strength, cohesion, adhesion to substrates and chemical/physical resistance. Solvent: toluene Solution of diisocyanate in toluene. Used to crosslink polyols (polyethers and polyesters), polyurethanes and elastomers (natural rubber, chloroprene) in coatings. Increases strength, cohesion, adhesion to substrates and chemical and physical resistance.
