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.

Rapid initial and through drying, along with good brushability. High filmhardness and abrasion resistance. Very good resistance to chemicals and water. Single binder in wood, industrial and floor finishes. Combinations with other long oil alkyds for improved drying and resistance. VIALKYD TO 608 is an oil-modified polyurethane resin which doesn't contain free isocyanate and is characterized by rapid initial and through-drying and high resistance to water after appropriate drying. It is used as single binder in wood, floor and industrial finishes and in primers. In combination with long-oil alkyd resins its drying properties are considerably improved. Addition of up to 30 % of VIALKYD TO 608 to other long-oil alkyd resins does not impair their respective outdoor performance. Wood and industrial finishes Rapid drying and high resistance to chemicals and water are the most remarkable characteristics of VIALKYD TO 608. Finishes on the basis of VIALKYD TO 608 are readily brushable, display excellent flow properties and yield films of high hardness already after short drying. Combinations of VIALKYD TO 608 with other resins, e. g. VIALKYD AF 764 produce interesting results. Initial and through drying are considerably improved. The good weather resistance and brushability of VIALKYD AM 764 is not impaired in a 70 : 30 (solids content) blend of VIALKYD AM 764 and TO 608. VIALKYD TO 608 is also suitable for forced drying up to 70 °C. Floor finishes On account of its good drying properties and abrasion resistance VIALKYD TO 608 lends itself very well to the manufacture of floor finishes. Its high gloss films provide good surface protection for floors exposed to heavy wear

VIALKYD AS 6140sca/49SD60, directly after production, is supplied as a liquid pumpable urethane thixotropic alkyd, which can be used as sole binder or in combination with other alkyds for decorative paints and wood stains. After a while without stirring some thixotropy occurs which affects or inhibits pumpability (see Storage). Concerning gloss retention and weather resistance VIALKYD AS 6140sca/49SD60 shows better properties than polyamide thixotropic alkyds. The thixotropy of urethane thixotropic alkyds can be easier destroyed by stirring than that of polyamide thixotropic resins. Thixotropy can be activated and adjusted by adding a polar solvent, for example propylene glycol. In order to avoid cloudiness we recommend not to add more than four percent propylene glycol (calculated on resin solids). The activated and adjusted thixotropy will stay largely constant after ripening for one week longest. Recommended driers are cobalt (0.05 % metal, calculated on resin solids), zircon (0.15 % metal, calculated on resin solids), and calcium (0.1 % metal, calculated on resin solids). To avoid skinning we recommend the addition of about 1.5 % ADDITOL XL 297 (calculated on resin solids).

VIALKYD VAS 9904/70SNA is a pigmented pasts, finish enamels with high resistance to yellowing, air drying and oven drying. Thanks to the good weather resistant properties and to the high compatibility and solubility in many solvents, VIALKYD VAS 9904 is very good as binder for high concentration pigment pastes.
