VIACRYL SC 370/75SNA is an acrylic resin crosslinkable with aminoplasts or with polyisocyanates (two-component). It is a high dry extract oven paint for automotive finishes or industry. Addition resin to increase the dry extract, body and gloss of oven paints as well as 2-component systems. In combination with polyisocyanates for two-component systems forced air drying, with high dry extract. Base resin for pasta pigmentary.

VIACRYL SC 444/50BSNB is a top quality single coats for domestic appliance. Clear and pigmented exterior coatings for cans. Great hardness combined with good flexibility. Excellent chemical resistance. Viacryl SC 444 is an acrylic resin designed as sole binder in the formulation of clear or pigmented industrial paints. Recommended stoving schedule: 20 - 30 minutes at 170 - 180 °C. Domestic appliances, like refrigerators, washing machines can be coated with Viacryl SC 444 single coats, since it yields films with very great hardness and outstanding flexibility. Co-employment of low molecular weight epoxy resins increase flexibility and chemical resistance. A wide range of possibilities are offered when it is used as a clear and pigmented exterior coating for cans.

VIACRYL SC 121/60LG is a sole binder for road-marking paints. Fast drying primers and top coats for nonferrous metal and plastic substrates. It is used as road-marking paints Viacryl SC 121/60LG was especially developed as sole binder for road-marking paints. Road-marking paints based on this copolymer have excellent adhesion and abrasion resistance, permanent flexibility as well as good whiteness retention. It is, however, recommended to first conduct a trial application under the given conditions to ensure suitability. Coating of plastics One-coat paints based on Viacryl SC 121 show especially good adhesion to plastics such as PVC, acrylic sheet, polycarbonate and polyester reinforced components. Primers and top-coats on metallic substrates. In view of its fast initial and through drying as well as its good water resistance Viacryl SC 121 is suitable for formulation one-coat paints and industrial primers. Coatings based on this product show good adhesion to steel, aluminium and zinc. For aluminium substrates a binder pigment ratio of about 1 : 2 should be selected. For steel a ratio of 1 : 1.5 is recommended. Decorative finishes are generally pigmented in ratios of 1 : 1 (binder/pigment) on solids.

VIACRYL SC 341/60SNABAC has a superior radiance, high surface hardness, excellent weather resistance. Medium solid acrylic resin for uni-coloured automobile finishes and isocyanate systems. With light stabilizers for clear coats over metallic basecoats. Easy and safe application. Viacryl SC 341 is used in combination with amino resins, preferably with reactive melamine resins. Polyurethane based thickness layer coatings can be formulated in combination with aliphatic polyisocyanates (e.g. Desmodur N). Stoving paints Suitable crosslinkers for Viacryl SC 341 in the first place are butylated melamine resins in a resin solids ratio of from 70 : 30 to 80 : 20. Spray application of paints on Viacryl SC 341 is excellent. Even when applied in thick layer, there is only a slight tendency to saging on vertical surfaces and to blistering or popping during stoving. The paints may also be rendered thicotropic with silicates, without the gloss being reduced. Film properties. Film of paints on Viacryl SC 341 have a superior decorative performance, like radiant brilliance, excellent levelling and very good build besides great hardness and gasoline resistance. Weathering tests in Florida showed very finishes.
