dc.description.abstractThis study reports the preparation of polyurethane adhesives using polyols obtained from castor oil modified by a transesterification reaction with pentaerythritol and starch modified by glycosylation. The physical properties of the polyols such as hydroxyl value were determined and the infrared spectroscopic analysis of the polyols reported. The effect of varying the hydroxyl value in the polyols on physical properties of polyurethane coatings on wood and steel panels was determined. The characterization of polyurethane coatings carried out by IR spectroscopic analysis, scratch hardness resistance, impact resistance, lap shear strength, T-peel strength measurements, solvent resistance and chemical resistant determination were reported.en
