THIXATROL P2100W is a waterborne Rheological Additive.

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).

ZENTEN WATERPROOFING TAPE NO. 6931 is a self-adhered, waterproofing airtight tape designed for sealing building joint areas. This product has a butyl rubber adhesive that offer superior adhesion durability. It is suitable for vertical or horizontal joints, ideal for waterproofing of joints in precast concrete facades, joints in walls, floors, balconies, around window or door frames, joints between brickwork, blockwork, masonry, wood and concrete or metal frames and joints between different building materials with dissimilar coefficients of expansion.
