THIXATROL P2100W is a waterborne Rheological Additive.

ADDITOL XL 102 is used to improve the effectiveness of paint removers containing paraffine and wax. Post treatment with organic solvents is not necessary.

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).

LICOWAX E FLAKES is an ester of montanic acids with multifunctional alcohols. The montanic acids contained in raw montan wax are straightchain, unbranched monocarboxylic acids with a chain length in the range of C28-C32. As a result of the long chain these montanic acids have a high thermostability and a low volatility as well as a low tendency to migration. LICOWAX E FLAKES is used as lubricant and dispersing agent in a wide variety of polymers like PVC, PS, PBT, PA, PDM, PC, TPU.
