Applications:
Tolonate™ D2 is typically used as a crosslinker of hydroxylated polymers notably polyesters and polyacrylates to prepare heat activated one component polyurethane systems for weatherable coatings giving excellent mechanical properties in conjunction with outstanding resistance to solvents, abrasion and chemical products. Tolonate™ D2 is commonly used in Automotive OEM formulations, can and coil coatings and other general industrial coatings on metal. The curing conditions are generally 20 to 40 minutes at 140-160°C (285-305°F) or 30 to 35 seconds at 320°C (PMT = 232 / 241°C).
