SELF-ETCHING CEMENTITIOUS SUBSTRATE COATING COMPOSITION
Described is a method for producing a coating with an aqueous coating composition AC, the method including: a) applying the aqueous coating composition AC to a cementitious substrate; and b) curing the applied aqueous coating composition AC. The aqueous coating composition AC includes at least one amino-functional copolymer VC and at least one epoxy silane ES and the coating composition has a pH in a range of 3 to 6.5. The weight ratio between amino-functional copolymer VC and epoxy silane ES (VC/ES) is in a range from 1.0 to 9.5. The composition can display self-etching properties on concrete surfaces, and thus, cementitious substrates do not have to be mechanically or chemically pretreated before the composition is applied.
