Soybean glue

Description

A vegetable glue made from the soybean cakes, i.e. the products left after the oil extraction. Developed in 1922, soybean glue is made from the alpha protein fraction. Additives can include, clay, nut shell flour, wood, flours, deformers, limes, sodium silicate, starch, borax, or dispersing agents. Soybean glue is marketed dry, then activated with water. It provides stronger adhesion that other vegetable pastes (Brady 1971). Soybean glues are used for interior plywood and millwork as well as for sizing and coating paper.
