  • 2-component primer composition and method for producing coatings using the primer composition
    Patent number: 9790316
    Abstract: The present invention relates to an aqueous two-component primer composition comprising (1) a paint base component comprising (A) at least one polyurethane resin having an OH number of 5 to 60 mg KOH/g, (B) zinc phosphate, (C) at least one pigment, and (2) a curing component comprising (D1) at least one polyisocyanate which is an isocyanurate based on hexamethylene diisocyanate, (D2) at least one polyisocyanate which is a polyether-modified isocyanurate based on isophorone diisocyanate, where the stoichiometric ratio of isocyanate groups in the curing component to the complementary hydroxyl groups in the paint base component is greater than 2. The present invention further relates to a method for producing a coating on a metallic substrate, by applying the primer composition of the invention directly to a substrate. Moreover, the present invention relates to a substrate coated by the stated method.
