Applications of IR Spectroscopy for Two Component Polyurethane Coatings

Dr. J. Tennisanthuvan

Abstract :

Polyurethane coatings are formed from a chemical reaction between a polyol and a polyisocyanate hardener. Two component solvent based polyurethane coatings were prepared by blending of epoxy polyol and Toluene Di Isocyanate (TDI) hardener. The composition was based on the solid contents of the hydroxyl equivalent weights of epoxypolyol and NCO equivalent weight of TDI. After the film coated with the prepared polyurethane coatings, the various physical properties and mechanical properties were measured. The formation of the various functional groups like Hydroxyl group,methylene group was supported by FTIR spectral data. The IR data showed the conformation for the formation of polyurethane and in the thermal product formation.
