WANNATE HT 600 Isocyanate Hardener
What is WANNATE HT-600?
WANNATE® HT-600 (1,6-hexamethylene diisocyanate based polyisocyanate) is a low viscosity solvent-free aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI), colorless to a slightly yellowish transparent liquid.
The main applications for coatings based on WANNATE® HT-600 are automotive refinishing, transportation, industrial finishing, and plastics.
It can be used as the hardener component for lightfast two-component polyurethane coatings with high chemical and weather resistance, good gloss retention, and outstanding mechanical properties. Preferred co-reactants are polyacrylates or polyester polyols.
