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.
Claims20
A method of making an article comprising the steps of:
- (a) providing a first substrate having a first and a second side;
- (b) 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;
- (c) applying the adhesive composition onto the first side of the first substrate;
- (d) providing a second substrate having a first and a second side;
- (e) mating the first side of the second substrate directly on the adhesive composition to form the article;
- and
- (f) coalescing the adhesive composition by means of applying heat or radiation.
A method of making a multilayer substrate package comprising:
- (a) providing a first substrate, which is a substantially flat, having a first and a second side;
- (b) 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;
- (c) applying the adhesive composition onto the first side of the first substrate;
- (d) providing a second substrate, which is a substantially flat, having a first and a second side;
- (e) contacting the first side of the second substrate directly on the adhesive to form the article;
- (f) coalescing the adhesive composition to adhere the adhesive composition to the surface of the substrates by means of applying heat or radiation.
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.
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.
