Abstract
A self-stick insulation includes an insulation product and an adhesive coating applied to a major surface of the insulation product. The adhesive coating includes between about 5-15% by weight of the adhesive coating of at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA), between about 1 and 8% by weight of the adhesive coating of an alcohol amine, between about 25 and 50% by weight of the adhesive coating of a polyvinyl alcohol, and between about 20 and 40% by weight of the adhesive coating of a starch paste. The adhesive is activated with the application of liquid water.
