Powder coating pretreatment compositions, and methods of using and making the same

摘要

The present document describes a composition which comprises about 25% to about 40% (v/v) plasticizers such as 2-ethylhexyl benzoate and butyl benzyl phthalate, about 0.5% to about 2% (v/v) of monoethanolamine as degasser, about 5% to about 20% (w/w) of pH adjusting agents such as calcium carbonate and ammonium carbonate, and from about 30% to about 45% (v/v) of a phenol formaldehyde resin based adhesive comprising an epoxy consisting of epichlorohydrin. The document also describes processes of making the composition as well as methods of using the composition for the pretreatment of surfaces, for example wood surface, metal rock or plastic surfaces prior to further treatment.
