Model HF-4370/1
Type Blocked Polyurethane Crosslinker
Introduction The HF-4370/1 is a medium Molecular weight trifunctional aliphatic blocked polyurethane crosslinker primarily used in one-pack oven formulations for the production of light-stable, chemically resistant metal protective and decorative coatings. Combining HF-4370/1 with HF-4370/1 increases the flexibility of coatings prepared from trifunctional blocking crosslinkers.
Application Coil steel and electroplating coating
