Collagen-based adhesives

Quick-setting collagen-based adhesives for furniture and cabinet assembly that would become permanently insolubilized against the effects of high humidity if not actual wetting after normal cold cure.

Protein-Based Adhesives. Protein-based adhesives are normally used as structural adhesives they are all polyamino acids that are derived from blood, fish skin, casein [9000-71-9], soybeans, or animal hides, bones, and connective tissue (collagen). Setting or cross-linking methods typically used are insolubilization by means of hydrated lime and denaturation. Denaturation methods require energy7 which can come from heat, pressure, or radiation, as well as chemical denaturants such as carbon disulfide [75-15-0] or thiourea [62-56-6]. Complexing salts such as those based upon cobalt, copper, or chromium have also been used. Formaldehyde and formaldehyde donors such as hexametliylenetetraamine can be used to form cross-links. Removal of water from a protein will also often denature the material. 

ECM-based hemostatic aids function in both active and passive ways. Collagen or cellulose networks aid in platelet adhesion and organized clot formation. For instance, collagen-based products have gained popularity due to their postulated superior... 

Protein-based adhesives have been used for centuries. The present primary use for these adhesives is as a stmctural material to generate interior-grade plywood. The source of the proteins for these adhesives can be used in their classification. Thus, the proteins for these adhesives come from blood, fish skin, casein (milk derived), soybeans, animal hides, bones, and connective tissue (collagen based). This classification is useful for predicting the durability of bonds made with protein-based adhesives.
