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 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.

VIALKYD AV 608/60WS is easy to use, excellent weather resistance, good water and corrosion resistance, high gloss. Sole binder for aluminium paints with brilliant effect and good gloss retention. Used for zinc dust paints, mica iron paints, and anticorrosive paints. VIALKYD AV 608 is a styrene-modified oil which is characterized by high resistance to water and corrosion. In aluminium-pigmented paints it yields a brilliant effect, good gloss retention and excellent weather resistance. It is used as sole binder for high-build, readily brushable, air drying aluminium, zinc dust and mica iron paints, zinc chromate primers, and lead and chromate-free ground coats. On account of its high degree of water resistance it is used for paint coating of steel structures such as oil and gas tanks, hall and brigde constructions, etc. VIALKYD AV 608/60WS may show some cloudiness, which, however, does not influence the technical properties of the paint.

VIALKYD AY 402/50X is an extremely fast initial and through drying. Excellent recoatability at any time. Excellent adhesion to steel and aluminium. Superior protection against corrosion Excellent water resistance. Anticorrosive primers. Spraying fillers, knifing and spray putties. Air-drying and forced drying industrial and machinery paints. VIALKYD AY 402/50X is an air-drying acrylic modified phthalic resin with specific properties owing to additional modification with isocyantes. VIALKYD AY 402 is primarily used sole binder in the formulation of anticorrosive primers, and putties and for air drying and forced drying industrial enamels and machinery paints. Anticorrosive automobile primers Primers based on VIALKYD AY 402 show extremely rapid set and through drying, excellent recoatability at any time with VIALKYD AY 402 or other paints containing aggressive solvents. The compatibility with basic pigments affords formulation of zinc chromate primers and primer fillers with excellent perfomance, particularly in terms of superior corrosion resistance, mechanical properties and water resistance. It is also possible to formulate zinc chromate free primers on base of zinc phosphate.Spraying fillers and spraying putties VIALKYD AY 402, in spray putties and fillers, exhibits quick drying and thus quick sanding and excellent adhesion to steel and aluminium. VIALKYD AY 402 has excellent recoatability and gives very good surface without lifting. Industrial paints In the formulation of industrial and machinery paints, with adequate pigmentation VIALKYD AY 402 affords radiant gloss, extremely rapid drying, excellent adhesion to steel and non-ferrous metals. The paints can be forced-dried at 60 - 100 °C. With curing temperatures of from 60 °C upwards no driers are required.
