WANNATE HT-90BS 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.

QA AQUOLIN 268 is water dispersible HDI isocyanate, used as curing agents for areas such as textiles, adhesives and industrial coatings, and can also be used as additives to improve the performance of waterborne coatings.

VIALKYD AC 290/70MPAC has an excellent compatibility characteristics with alkyd stoving paints, thermosetting acrylic paints, NC-lacquers, acid curing enamels, alkyd- or acrylic-isocyanate enamels. Grinding resin for pigment pastes. VIALKYD AC 290 has been designed as grinding resin in the formulation of pigment pastes which have full compatibility with alkyd stoving paints, thermosetting acrylic paints, nitrocellulose enamels and acid curing enamels, alkyd- or acrylics- polyiscoyanate combinations. The pastes can be reduced with the respertive resins and give paints with the performance of irrelevant modified basic paint properties. VIALKYD AC 290 has a balanced functionality and is fully integrated into the cured film. Therefore, it must be fully considered as resin component for reaction with amine resins, polyisocyanates, nitrocellulose systems and acid curing systems. Up to a resin proportion of 30 % of VIALKYD AC 290, the performance of the binder resin is not influenced adversely. VIALKYD AC 290 shows yellowing resistance up to 30 min / 200 °C and acts up favourably to top quality alkyd resins. Solvent resistance is not adversely affected. At low curing temperatures, VIALKYD AC 290 shows good crosslinking and is thus also suitable for quick stoving 80 °C enamels. Owing to the excellent performance of VIALKYD AC 290 in a variety of paint formulations and due to the fact that VIALKYD AC 290 does not subdue the characteristics of the main binder, paint preparation can be substantially rationalized with this new grinding medium.

SETALUX 1200 XX-55 is in combination with aliphatic poly-isocyanates: fast drying and good adhesion on various substrates such as aluminium, steel, zinc plated steel, stainless steel. Good mechanical properties and good outdoor durability. It is used as fast drying industrial lacquers with good adhesion on metal substrates.
