    摘要: A roofing repair system including a multi-part primer and a water-activated overcoat composition. The multi-part primer includes a first part including a hydroxyl-functional (meth)acrylic (co)polymer, and a second part including a mixture of a hydrophilic polyfunctional aliphatic polyisocyanate and a hydrophobic polyfunctional aliphatic polyisocyanate, wherein a molar ratio of hydroxyl functionality in the first part to isocyanate functionality in the second part is less than 1. The water-activated overcoat composition includes at least one compound selected from polyketimines having amino groups attached to secondary carbon atoms, polyenamines, and oxazolidines. In some exemplary embodiments, the volume ratio of the multi-part primer to the water-activated composition is from 5:1 to 7:1. In certain exemplary embodiments, the multi-part primer is substantially free of organic solvents. A method of using the roofing repair system to repair the weathered surface of an elastomeric roofing membrane is also described.

    摘要: Methods for improving one or more surface properties of a sheet of paper or paperboard, which method comprises (a) coating at least one side of the sheet of paper or paperboard with a dispersion having a cationic zeta potential formed by combining (1) a mixture containing one or more anionic pigments with (2) one or more polyamine- epihalohydrin cationic wet strength resins at a coating weight of from about 0.1 g/m to about 20 g/m; (b) drying the coated sheet of paper or paperboard; (c) applying a functional barrier top coating that resists one or more of the following: liquid water, water vapor, gas permeability, oil and grease, slip, and static or an anionic latex based pigment coating that imparts improved opacity, brightness, or printability. The invention also includes the dispersions as well as paper or paperboard coated with the dispersion.
