Abstract
Methods of making and using adhesive compositions based on oilseed solids are provided. Also provided are adhesive compositions made using the methods. The adhesive compositions are made by mixing defatted oilseed solids with a polyisocyanate to form a non-aqueous adhesive composition and, subsequently, mixing the non-aqueous adhesive composition with water to form an aqueous adhesive composition.
Claims20
A composition comprising:
- defatted oilseed solids;
- and
- a polyisocyanate, wherein the composition is a particulate solid, and the defatted oilseed solids and the polyisocyanate make up at least 90 weight percent of the composition.
A method of making an adhesive composition, the method comprising:
- mixing a particulate solid composition comprising defatted oilseed solids and a polyisocyanate to form a non-aqueous adhesive composition;
- and
- mixing the non-aqueous adhesive composition with water to form an aqueous adhesive composition.
A method of bonding substrates, the method comprising:
- mixing a particulate solid composition comprising defatted oilseed solids and a polyisocyanate to form a non-aqueous adhesive composition;
- mixing the non-aqueous adhesive composition with water to form an aqueous adhesive composition;
- applying the aqueous adhesive composition to a surface of at least one of the substrates;
- and
- pressing the applied adhesive composition between the substrates.
