WANNATE HB-75B 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.

ADDITOL VXW 6386 Easy emulsifable defoamer, espacially for high quality waterborne sytems, at there conventionally mineral-oil or silicon based defoamers cause decrease the surface quallity of the film (orange peel, craters). At forced and stoving drying paints it can observed a higher cissing free filmthickness. ADDITOL VXW 6386 is qualified for following waterborne systems: stoving enamel based on alkyd- or acrylic-melamine resin, 2 component acrylic-isocyanate paints, paints based on waterdilutable alkyd resin and gloss and semigloss dispersion paint.

POLYETHERAMINE MA 2200 is a difunctional primary amine. Its mainchain is consisted of repeating oxypropylene units. Average molecular weight = 2000 g/mol.

Prevents the sedimentation of pigments in paints. Improves the pigment-wetting during dispersion. In many paint systems the floating of pigments in pigment-mixtures is prevented. The tendency to flow off is reduced and the covering of edges is improved. Suggested for all solvent based and solvent-free paint systems. ADDITOL XL 270 is usually compatible with solvent based and solvent-free binders. It prevents the sedimentation of pigments in paints. The rheological character of paints is improved. The tendency to flow on vertical surfaces is reduced. The edges of substrates are better covered in case of dipping application. The drying of oxidatively drying systems is not influenced by ADDITOL XL 270, if the appropriated dose is used. Also the efficiency of siccatives in paints, stored for a long time, is not reduced using ADDITOL XL 270. Considering anti-corrosive paints, there is no corrosion-resistance loss by using ADDITOL XL 270. It is recommended to be used for the activating of organophile bentonites and it improves the effect of pyrogene silica.
