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.

VIALKYD AY 120/65XMPAC is a very rapid initial and through drying. Quick rise in hardness, long pot life. Good body, excellent gloss retention, superior weather resistance. It is used in combination with aliphatic polyisocyanates, preferably with Desmodur N, gives fast drying brilliant car refinishing enamles with good build and finishing enamels for railroad coaches, busses, etc. VIALKYD AY 120 may also be used for the formulation of two coat metallic finishes.

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 VAF 6091 is a High Solids long oil alkyd resin for the production of High Solids primers, wood stains and top coats. A solid content of 90 % by weight is possible in white high gloss paints. Application properties are the same as with normal conventional alkyds. Applying paints based on VIALKYD VAF 6091 on primers usually need only one layer, which leads to additional reduction of solvent emission. For environmental reasons we suggest the use of lead-free driers, for example zircone.
