ADDITOL XW 330 is a wetting and dispersing agent for inorganic pigments and extenders in aqueous systems and for stabilizing emulsion paints. Prevents thickening. ADDITOL XW 330, together with polyphosphates (e.g. Calgon N), is used in emulsion paints for dispersing and wetting in pigments and extenders. The product can be employed for all the usual emulsions, e.g. homopolymer and copolymer polyvinyl acetate, polyacrylic and styrene/acrylic copolymer dispersions. ADDITOL XW 330 improves the storage stability of highly pigmented emulsion paints and prevents them from thickening.

ADDITOL XW 6535 is a grinding medium, especially designed for low VOC decorative systems. The special composition allows high pigment loading and very good compatibility to common decorative water borne and solvent borne binder systems. For the production of universal pigment concentrates based on ADDITOL XW 6535 we recommend to use the following ADDITOL grades: ADDITOL VXW 6205 (dispersing agent for inorganic pigments) ADDITOL VXW 6387 (anti settling ADDITOL VXW 6372 (preserver) and ADDITOL VXW 6211 (defoamer).

BECKOCURE EH 2260W/41WA is an hydrophobic amine hardener especially for the formulation of waterborne metal coatings, free of volatile basic amines and solvents. In combination with epoxy dispersions fast drying Primers and Monocoats with excellent corrosion protection and very good non-sagging properties can be formulated. The product shows excellent application behaviour and a very robust performance even on poorly prepared surfaces. Beckocure EH 2260w is used together with solid epoxy resin dispersions or emulsified liquid resins. Best results are obtained using 50 - 75 % of the stoichiometric amount of hardener. The films cure rapidly at room temperature but can also be dried at elevated temperatures. Grinding of the pigments can be done in Beckocure EH 2260w or as well in shear stable epoxy dispersions (e. g.: Beckopox EP 2384w, Beckopox EP 386, Beckopox EP 387 or Beckopox VEP 2381w). The mill base temperature should not exceed 40 °C. The use of binder-free pigment pastes is recommended when the grinding temperature cannot be controlled. Dilution can be done with Beckocure EH 2260w or an epoxy dispersion.

ADDITOL XW 329 is a paint additive to enhance mar resistance and slip and levelling, particularly of water dilutable paints.ADDITOL XW 329 is a silicone resin supplied as low viscous solvent containing liquid. ADDITOL XW 329 enhances the slip of the film surface and thus protects it from scratching and abrasion. Furthermore, ADDITOL XW 329 improves levelling of the film and prevents film defects. Thus the surface quality ingeneral is improved. In many cases gloss is also enhanced. ADDITOL XW 329 can be employed in water dilutable paints of any type. Reduced intercoat adhesion has not been experienced with the use of ADDITOL XW 329. The effect of ADDITOL XW 329 varies with the formulation of the paint. A level of 0.1 - 0.3 % of ADDITOL XW 329 on the finished paint may serve as a guide.
