As a flow- and pumpable paste ADDITOL XL 280 prevents settling and improves wetting of pigments in solvent- and waterborne paints systems. ADDITOL XL 280 improves paint stability. ADDITOL XL 280 is a highly effective additive for all industrial finishes. The easy handling of this material, owing to its favourable rheological properties, saves material and manufacture costs and simplifies the dosage. Difficult dispersible pigments and extenders are more easily and rapidly wetted and stabilized by the action of ADDITOL XL 280. The rheological properties of the coating are favourably affected leading to less tendency to run-off on vertical surfaces and improving edge coverage in dip coating.

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).
