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® 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® HT-100 PLUS as a 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) with a residual NCO monomer content of < 0.1%.

WANNATE® TT-150E can be used as hardener component for fast drying, two-component polyurethane coatings. WANNATE® TT-150E is a mixture of an aromatic polyisocyanate based on toluene diisocyanate (TDI) and ethyl acetate.
