  • Starch-based aqueous adhesive compositions and uses thereof
    Patent number: 10723922
    Abstract: The invention relates to starch-based aqueous adhesive compositions and uses thereof. Provided is an aqueous adhesive composition comprising highly branched starch (HBS) obtained by treatment of starch or starch derivatives with a glycogen branching enzyme, and further comprising a carboxymethyl (CM) polysaccharide derivative, such as a carboxymethyl ether of starch, cellulose or a combination thereof. Also provided is a method for adhering a first substrate to a second substrate, comprising applying to at least said first or said second substrate said starch-based adhesive, and a glued or glueable product obtainable thereby.
    Type: Grant
    Filed: August 13, 2019
    Date of Patent: July 28, 2020
    Assignee: COÖPERATIE AVEBE U.A.
    Inventors: Pieter Lykle Buwalda, Anna Maria Dijk-van Delden, Anne Margriet Hofman-de Dreu

  • Starch-containing adhesive compositions and uses thereof
    Patent number: 10233362
    Abstract: The invention relates to aqueous adhesive compositions comprising a starch, in particular to starch-based adhesives for bonding paper products. Provided is an aqueous adhesive composition comprising a starch derivative and a clay, wherein said starch derivative is a highly branched starch (HBS) obtained by treatment of starch or starch derivatives with a glycogen branching enzyme (EC 2.4.1.18), and wherein the weight ratio of said HBS to said clay is within the range of from about 1:1 to 1:4.
