Patent Images
1. A process of preparing a composite structure comprising:
- applying to one or more substrates an adhesive composition comprising a) a protein component, b) an azetidinium functionalized polymer selected from the group consisting of amine-epichlorohydrin polymer and polyamidoamine-epichlorohydrin polymer, and c) one or more viscosity-modifying components; and
heating and pressing two or more of the substrates together to form the composite structure;
wherein the composition has a pH of from about 4.5 to less than 7.5;
a Brookfield viscosity of between about 1,000 cps and about 200,000 cps; and
a solids content of from about 5% to about 75%.
