Aquacer 840 Oxidised polyethylene wax(HDPE) BYK Chemie Flow / Levelling agent >> Wax Wax >> Polyethylene wax Coatings >> Waterborne Automotive OEM >> Top coats >> Clearcoat Automotive refinishing >> Clearcoat General Industrial /Maintenance >> Topcoat / One-coat finishes >> Clearcoat water Aquacer® 840 is cationic aqueous emulsion of an oxidized polyethylene wax (HDPE). Wax emulsion to improve the surface properties of aqueous automotive coatings. Short wave defects (mottling, Bénard cells) are minimized and the flip-flop effect is improved. In addition to this, flow and leveling of the subsequent clearcoat is enhanced. The additive is also suitable for other aqueous industrial coatings. Cationic aqueous emulsion of an oxidised polyethylene wax (HDPE). Used in automotive and industrial coatings. Offers improved flip-flop effect, flow and levelling. Reduces short wave defect (mottling, Bernard cells).
