VALIRES HA 040.01 is a pualkyd emulsion.

SETAL 142 XX-60 is very fast drying, good elasticity and yellowing resistance (also at elevated temperature), good adhesion on steel. It is used as fast drying industrial topcoats. Fast drying corrosion resistant primers. General purpose stoving enamels.

VIALKYD AN 928/65MPAC is a medium reactivity, high hardness. Superior abrasion and impact resistance. Radiant brilliance. Two-pack polyurethane enamels for metal and wood. VIALKYD AN 928 is a branched hydroxyl functional polyester suitable as crosslinker for aliphatic and aromatic polyisocyanates. The components react at ambient temperature and give films with outstanding light fastness and gloss retention. The high reactivity affords crosslinking particularly with Desmodur N, Desmodur L and Desmodur HL grades. VIALKYD AN 928 can be used as sole binder in the formulation of clear and pigmented paints for coachworks and high rise panels affording excellent resistance to abrasion, chemicals and water. The substrates can be wood, metal or plastic.

VIALKYD AC 451N/70SNB is used as automotive finishes with high gloss and excellent weather resistance and paints for household appliances. It is used as stoving enamels VIALKYD AC 451n/70SNB is suitable for cross-linking with amino resins especially to formulate high quality stoving systems for automotive top-coats and one-coat systems for household and electrical appliances. Films based on VIALKYD AC 451n have good gloss, high body and excellent outdoor durability as well as resistance to petrol and UV radiation. Excellent impact resistance, flexibility, adhesion and surface hardness round out of VIALKYD AC 451n properties. VIALKYD AC 451n is generally used with reactive conventional melamine resins in ratios of 70 : 30 to 75 : 25 (on solids). Depending on the reactivity of the melamine resin curing takes place at temperatures of 120 - 140 °C for 30 min. When using high reactive dehydrated castor oil alkyd resin grades such as VIALKYD AR 340 in combination with melamine resin it is possible to reach curing conditions of 30 min 100 - 120 °C. In addition it is possible using an acid catalyst (e. g. 0.5 - 1 % p-toluene sulphonic acid, 10 % in xylene) to increase reaction speed to enable on-line repair in the automotive industry.
