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).

LICOCENE PP 1602 GR granules is a low melting, metallocene-technology based propylene-ethylene copolymer wax, which exhibits a low degree of crystallinity.

HOSTANOX OSP 1 MICRO PILLS is a high efficient antioxidant and metal deactivator which prevents the auto-catalytic decomposition of polyolefins. The usage of metal deactivators is mandatory as long as the polyolefin based finished article comes into contact with transition metals, such as Cu, Fe, Ni, Ti, etc.
