Abstract

The paper describes the history, characteristics, uses, and limitations of soya-bean glue, or generically of seed-residue glue. This is the newcomer in the glue field, its use practically dating from 1923. The adhesive base of the seed-residue glues is the cake or meal resulting from the oil-pressing of soya beans, peanuts, cotton seed, etc. In the manufacture of plywood it is stated that the tonnage of the oil-seed-residue glues equals that of any other type of glue. In connection with the soya-bean glues there has been developed the use of carbon bisulphide as an agent to increase water resistance.
