发明名称 Coating for granulated products to improve granule adhesion, staining, and tracking
摘要 A building material product and a method of making building material products, having increased resistance to granule rub off and staining. The building material product comprises a substrate having embedded granules and an acrylic latex coating positioned on the granules, where the polymer of the acrylic latex coating has the repeating structural unit [CH2—C(R1)(R2)], where R1 is hydrogen or C1-C8 alkyl; R2 is hydrogen, cyano or—COOR; and R is a linear or branched hydrocarbon containing 1-22 carbon atoms, with the proviso that R1 and R2 are both not hydrogen. The method includes applying this acrylic latex water based composition to a granule embedded substrate.
