Tolonate™ HDT 90 B

Tolonate™ HDT 90 B by Vencorex is an aliphatic polyisocyanate based on hexamethylene diisocyanate trimer (HDI homo-polymer). Acts as a crosslinking agent. Offers excellent mechanical properties in conjunction with outstanding resistance to solvents, abrasion and chemicals. Soluble in esters, ketones, aromatic hydrocarbons. Ideal for producing PU coatings when aesthetic and durability of coating are critical. It is typically used in combination with hydroxylated polymers, especially polyesters and polyacrylates in the preparation of two components systems for weatherable coatings. Used in high-solids two-component polyurethane coatings and varnishes. Recommended for exterior protective coatings for automotive OEM, car repair, industrial machinery and plastic parts. Tolonate™ HDT 90 B can also be used in aromatic solvent-free 2K polyurethane coatings.
