Tolonate™ D2 is a blocked aliphatic polyisocyanate (HDI homopolymer), supplied at 75% solids in aromatic solvent. It is typically used as a crosslinker of hydroxylated polymers, notably polyesters and polyacrylates, to prepare heat activated one-component polyurethane systems for weatherable coatings. It gives excellent mechanical properties in conjunction with outstanding resistance to solvents, abrasion and chemical products. This product is commonly used in Automotive OEM formulations, can and coil coatings and other general industrial coatings on metal.
