Abstract: The present invention provides methods of making block resistant coated substrates, such as boards, sheets, panels, tiles, assemblies or membranes for use in building and construction, such as for exterior use, the methods comprising coating a substrate with a coating composition of one or more aqueous emulsion polymers and one or more photoinitiators, such as a hydrogen abstraction initiator, onto the substrate to form a coated substrate, at least partially curing or drying the coating, and exposing the at least partially cured coating on the coated substrate to UV light to cause the photoinitiator to react with itself or with the coating composition. In the methods, the wavelength of the UV light used preferably matches or at least overlaps the spectral activation or excitation window of the one or more photoinitiators.

Abstract: A formulation contains an anionically stabilized dispersion of polymer particles, a polymeric polyamine and an inorganic filler has a pH in a range of 6.0 to 8.5, viscosity greater than 15000 centipoise, and is free of volatile base, aminosilanes, and quaternary poly(allylamine).
