VIALKYD AC 290/70MPAC has an excellent compatibility characteristics with alkyd stoving paints, thermosetting acrylic paints, NC-lacquers, acid curing enamels, alkyd- or acrylic-isocyanate enamels. Grinding resin for pigment pastes. VIALKYD AC 290 has been designed as grinding resin in the formulation of pigment pastes which have full compatibility with alkyd stoving paints, thermosetting acrylic paints, nitrocellulose enamels and acid curing enamels, alkyd- or acrylics- polyiscoyanate combinations. The pastes can be reduced with the respertive resins and give paints with the performance of irrelevant modified basic paint properties. VIALKYD AC 290 has a balanced functionality and is fully integrated into the cured film. Therefore, it must be fully considered as resin component for reaction with amine resins, polyisocyanates, nitrocellulose systems and acid curing systems. Up to a resin proportion of 30 % of VIALKYD AC 290, the performance of the binder resin is not influenced adversely. VIALKYD AC 290 shows yellowing resistance up to 30 min / 200 °C and acts up favourably to top quality alkyd resins. Solvent resistance is not adversely affected. At low curing temperatures, VIALKYD AC 290 shows good crosslinking and is thus also suitable for quick stoving 80 °C enamels. Owing to the excellent performance of VIALKYD AC 290 in a variety of paint formulations and due to the fact that VIALKYD AC 290 does not subdue the characteristics of the main binder, paint preparation can be substantially rationalized with this new grinding medium.

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 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 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.
