Adhesive having insulative properties

Abstract

An improved adhesive composition having increased insulative properties is provided. The adhesive composition having improved insulative properties includes a starch component; an alkaline component; sodium tetraborate; water; and a plurality of expandable microspheres. Products having improved insulation capabilities and methods of making the products having improved insulation capabilities are also provided. The present adhesive and products including the adhesive is environmentally friendly.

What is claimed is: 
     
         1 : A multilayer substrate package comprising:
 (a) a first substrate, which is a substantially flat, having a first and a second side;   (b) a second substrate, which is a substantially flat, having a first and a second side; and   (c) preparing an adhesive composition having improved insulative properties, comprising (i) a starch component; (ii) an alkaline component; (iii) sodium tetraborate;   (iv) water; and (v) a plurality of expandable microspheres;   wherein the adhesive composition is coalesced onto the first and the second substrates.   
     
     
         2 : The multilayer substrate package of  claim 1 , wherein the adhesive composition has greater than 10% moisture content. 
     
     
         3 : The multilayer substrate package of  claim 1 , wherein the adhesive composition contacts the first and the second substrates in a pattern of dots, stripes, waves, checkerboards, or a polyhedron shape that have substantially a flat base. 
     
     
         4 : A multilayer substrate package comprising:
 (a) a first substrate, which is a substantially flat, having a first and a second side;   (b) a second substrate, which is a substantially flat, having a first and a second side; and   (c) a set adhesive composition, sandwiched between the first substrate and the second substrate, comprising preparing an adhesive composition having improved insulative properties, comprising (i) a starch component; (ii) an alkaline component; (iii) sodium tetraborate; (iv) water; and (v) a plurality of expandable microspheres;   wherein the set adhesive composition contacts the first and the second substrates in a pattern of dots, stripes, waves, checkerboards, or a polyhedron shape that have substantially a flat base.
