Self-stick insulation and methods
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.
1. A self-stick insulation, comprising:
an insulation product, the insulation product comprising:
a length;
a width;
a thickness; and
a first major surface and a second major surface that extend the length and the width of the insulation product;
an adhesive coating applied to the first major surface and the second major surface of the insulation product, the adhesive coating comprising:
between about 30-55% by weight of solids of the adhesive coating of at least one of polystyrene-maleic anhydride (SMA) and polyacrylic acid (PAA);
between about 10-15% by weight of solids of the adhesive coating of an alcohol amine; and
between about 30-60% by weight of solids of the adhesive coating of at least one of a polyvinyl alcohol and a starch;
wherein the adhesive coating is activated with an application of liquid water; and
a facer adhered to the second major surface of the insulation product via the adhesive coating.
2. The self-stick insulation of claim 1 , wherein the adhesive coating comprises a non-continuous and non-uniform coating atop the first major surface.
3. The self-stick insulation of claim 1 , wherein the insulation product comprises 1-8% by weight of the adhesive coating after the adhesive coating is applied and dried to the insulation product.
4. The self-stick insulation of claim 1 , wherein the facer comprises at least one material selected from the group consisting of a paperboard material, a cardboard material, a foil, a scrim, and a polymer material.
5. The self-stick insulation of claim 1 , wherein the facer comprises one or more flanges that extend beyond an edge of the second major face of the insulation product.
6. The self-stick insulation of claim 1 , wherein the insulation product comprises at least one material selected from the group consisting of fiberglass, mineral wool, slag wool, rock wool, and foam.
7. The self-stick insulation of claim 1 , wherein the alcohol amine comprises at least one of monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA).
8. The self-stick insulation of claim 1 , wherein the adhesive coating passes a D 903 bonding strength (Ambient) test based on standards of ASTM C 916.
9. The self-stick insulation of claim 1 , wherein the adhesive coating passes a C 916/Dl 151 Bonding Retention (90 days@ 160° F.) test based on standards of ASTM C 916.
10. The self-stick insulation of claim 1 , wherein the adhesive coating passes a C 916 Edge Burning test based on standards of ASTM C 916.
