WANNATE® HTBL-275MS can be used in the formulation of weather-stable, lightfast, chemically resistant and highly heat-stable one-component polyurethane stoving coatings for use in automotive finishing. Compared with polyisocyanates blocked with butanone oxime, WANNATE® HTBL-275MS allows a reduction in the stoving temperature of approx. 10 ℃, with no decrease in solvent and chemical resistance.

WANNATE® HTBL-175S can be used as the hardener in colorfast and weather-stable, one-component polyurethane coatings. The stoving temperature can be significantly reduced by the addition of a catalyst, e.g. dibutyltin dilaurate (DBTL), without reducing the storage stability. The product is used in high-grade industrial finishes (electrical appliances, small components, can coatings, coil coatings, etc.) and in primer surfacers and topcoats for automative finishing. WANNATE® HTBL-175S can also be used as an additive in conventional stoving systems to improve the flexibility and adhesion.

WANNATE® IT-170S 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. Based on its high hardness, it is normally mixed with WANNATE® HT series. The main applications for two-component coatings based on WANNATE® IT-170S are automotive OEM and automotive refinishing. WANNATE® IT-170S works as assistant resin in alkyd spray coating system for its high drying speed. This kind of coating is widely used in automotive refinish and industrial coatings.

WANNATE® HT-300 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. Preferred co-reactants are polyacrylates or polyester polyols. It is a solvent free aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).
