Abstract
A method of using a self-stick insulation. The method includes providing a piece of insulation product with an adhesive coating. The adhesive coating includes polystyrene-maleic anhydride (SMA) and/or polyacrylic acid (PAA); an alcohol amine; and at least one of a polyvinyl alcohol and a starch. The adhesive coating is then activated with liquid water. Once the adhesive coating is active, the insulation product is attached to a surface with the adhesive coating.
Claims20
A method of making a self-stick insulation, comprising:
- applying a water-activated adhesive coating to a major surface of an insulation product, the water-activated adhesive coating comprising:
- at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA) having a molecular weight of between 500 g/mol and 5000 g/mol;
- an alcohol amine;
- water;
- and
- at least one of a polyvinyl alcohol and a starch;
- and
- drying the water-activated adhesive coating on the major surface to evaporate the water to form a dry water-activated adhesive coating layer on the major surface.
