ADDITOL VXW 6386 Easy emulsifable defoamer, espacially for high quality waterborne sytems, at there conventionally mineral-oil or silicon based defoamers cause decrease the surface quallity of the film (orange peel, craters). At forced and stoving drying paints it can observed a higher cissing free filmthickness. ADDITOL VXW 6386 is qualified for following waterborne systems: stoving enamel based on alkyd- or acrylic-melamine resin, 2 component acrylic-isocyanate paints, paints based on waterdilutable alkyd resin and gloss and semigloss dispersion paint.

ADDITOL VXL 4950 is a product without special pre-treatment of plastic materials such as polyethylene, polypropylene and polyamide (e.g. corona discharge, roughening, flame or chromic acid treatment) good adhesion of coatings can be obtained after applying a thin adhesion promoting layer of ADDITOL VXL 4950 to the surfaces. For plastic substrates made of polyethylene a short period of additional UV-irradiation of this film is recommendable. In general irradiation of ADDITOL VXL 4950-coatings can further improve adhesion .

ADDITOL VXL 6237 N improves the wetting of very difficult-to-disperse pigments, specially in aromatic free solventborne highgrade automotive series, car repair and industrial paints. Shortens the dispersing time. Prevents the reflocculation of the pigments. Improves gloss and levelling. ADDITOL VXL 6237 N permits a higher pigmentation of the mill base without increasing viscosity and shortens the dispersing time. The ready pigment pastes and paints are distinguished by a high colloidal stability and do not tend to a reflocculation of the pigments. By using ADDITOL VXL 6237 N in solvents containing acrylate systems, a stabilizing effect on the binder can be observed.

ADDITOL VXW 4973 is an easily emulsifiable defoamer with very good incorporating ability. It is suited for defoaming of coarse-disperse to fine-disperse (plastic) dispersions on the basis of PVAC, PVC, acrylates and their copolymerisates. Also low-viscous products may be defoamed with ADDITOL VXW 4973.
