Synthesis and Characterization of Castor Oil based Polyurethane Adhesive for Wood Substrates

Abstract: This project gives the idea about use of raw materials from renewable sources to synthesis polyurethane adhesive which is important from social, environmental and economic view as compared to those produced form petrochemical sources. Polyurethanes based on castor oil were synthesized with polyols and toluene diisocyanate, and amine as a catalyst. The degree of swelling, mechanical properties, and polymerization kinetics was greatly affected by the diisocyanate nature. The aim of this paper is to give a fundamental description of castor oil and various application of polyurethane adhesive like wood, metal, etc In the beginning of the 21st century, the increasing concern over environmental pollution has forced the industry to develop environmentally friendly adhesive. Castor oil based polyurethane adhesive from renewable sources are greatly appreciated by the research since they can be produced at low prices and can be biodegradable, as compared to those produced from petrochemical sources. By use of this method biodegradable castor oil based polyurethane adhesive made.
