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 comprising at least one of fiberglass, mineral wool, slag wool, rock wool, or foam, 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, the first major surface and the second major surface forming opposite surfaces of the insulation product;
an adhesive coating applied to the first major surface, the 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, 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 using an adhesive, the facer comprising a foil, a scrim, and a kraft paper.
2 . The self-stick insulation of claim 1 , wherein:
the adhesive coating is activatable by between 5% and 15% water by weight of the insulation product.
3 . The self-stick insulation of claim 1 , wherein:
the adhesive coating remains inactivated in up to 100% relative humidity.
4 . The self-stick insulation of claim 1 , wherein:
in a dry state the adhesive coating makes up between 1% and 8% by weight of the insulation product.
5 . The self-stick insulation of claim 1 , wherein:
in a dry state the adhesive coating has a thickness of between 0.01 inch and 0.02 inch.
6 . The self-stick insulation of claim 1 , wherein:
the adhesive coating is applied in a wavy pattern, in a parallel line pattern, in a crossing line pattern, in a honeycomb pattern, in a dot pattern, or a splat pattern.
7 . The self-stick insulation of claim 1 , wherein the adhesive and the adhesive coating have a same composition.
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/D1 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.
