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 [CH&#x2014;C(R)(R)], where Ris hydrogen or C-Calkyl; Ris hydrogen, cyano or &#x2014;COOR; and R is a linear or branched hydrocarbon containing 1-22 carbon atoms, with the proviso that Rand Rare both not hydrogen. The method includes applying this acrylic latex water based composition to a granule embedded substrate.

Method for coating granulated products to improve granule adhesion, staining, and tracking

Coating for granulated products to improve granule adhesion, staining, and tracking

Methods of making a single ply protective covering and of installing such a covering are disclosed. The method of making includes (a) providing a single ply thermoplastic roofing membrane, and (b) coating the single ply thermoplastic roofing membrane on its bottom surface with a 1-50 mil layer of a pressure sensitive adhesive mixture consisting essentially of polyisobutylene and at least one polymer comprising conjugated diene monomers. The method of installing includes (a) providing a single ply thermoplastic roofing membrane, (b) cutting the single ply thermoplastic roofing membrane to a selected size, (c) positioning the single ply thermoplastic roofing membrane on a portion of a roof, and (d) bonding the membrane to the roof.

Thermoplastic single ply protective covering

Improved single ply, water proof roof coverings having an extruded pressure sensitive rubber-based adhesive backing for attachment to a substrate such as the roof of a building or a transport vehicle, the adhesive consisting of polyisobutylene and at least one polymer comprising conjugated diene monomers.

Improved single ply, water proof roof coverings having an extruded pressure sensitive rubber-based adhesive backing for attachment to a substrate such as the roof of a building or a transport vehicle, the adhesive comprising a thermoplastic rubber containing at least 25% butyl rubber in combination with polyisobutylene and low molecular weight polybutene.
