A solvent free, aqueous emulsion of special polyester resin. It is used to promote the adhesion of coatings on critical substrates and the intercoat adhesion of multicoat systems. It works well on metallic, mineral and various other plastic substrates. The resin has been proven effective in improving gloss, flexibility, and corrosion protection. It is also highly stable against light, weathering and saponification. The resin is used in water soluble coating systems based on air-drying and heat curing binders. |
