Polyureas based on hexamethylene diisocynate (EDDI), synthesised by the reaction of HDI with water to produce prepolymers with an average number of monomer units of between 3 and 4. The products are used in the manufacture of paints and varnishes
Polyisocyanurates based on hexamethylene diisocynate (EDDI), synthesised by the reaction of HDI to produce prepolymers with isocyanurate links between monomer units. The prepolymers have an average number of monomer units of between 3 and 5. The products are used in the manufacture of paints and varnishes.
