Abstract
A method for forming a coating composition for coating a substrate comprising: blending an asphalt material; a polymer that is not a polyol; and a polyol wherein the polyol has a molecular weight of about 1000 to about 5000. Also, included are coated articles that comprise a substrate coated with a layer of the coating composition.
Claims24
A process for making a hot melt blend composition to coat substrates comprising forming a hot melt blend of components consisting of
- a. an asphalt material up to about 85% by weight of the total composition wherein the asphalt material is a de-asphaltized grade asphalt;
- b. a polymer that is not a polyol selected from the group consisting of a natural rubber, a synthetic rubber, a thermoplastic rubber, a styrene butadiene styrene (SBS), an ethylene vinyl acetate (EVA), a thermoplastic polymer, an acrylic polymer, a polyurethane polymer, a styrenated-acrylic polymer, a styrene/butadiene copolymer, an EPDM copolymer, atactic polypropylene and mixtures thereof;
- and
- c. a polyol selected from the group consisting of a polyether polyol, a natural polyol, a polyester polyol and mixtures thereof;
- wherein the polyol has a molecular weight of about 1000 to about 5000 and the polyol is present in an amount no greater than about 30% by weight of the total composition.
