HDI Low Viscosity WanHua HT-600
ABOUT:
WANNATE® HT-600 is a low viscosity solvent-free polyfunctional aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI). HDI trimer can be used as the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties. The main applications for coatings based on HDI trimer are automotive OEM, automotive refinishing, transportation, industrial finishing and plastics.
Applications:
Automotive refinish, wood coating, 3C coatings, other high solid and low viscosity systems.
Characteristics:
-
Low viscosity, especially suitable for the 2k solvent freepolyurethane coatings
-
High gloss, excellent leveling property
-
Good dilution stability
-
High NCO content. Quantities of the curing agent is decreased inthe formulation, which is much more economic.
