Abstract: FTIR,TG and TBA tochniques have been used to study the curing process of abrasion-resistant organosilicone coatings used for transparent plastics. The dehydration rate of the associated hydroxy groups in the organosilicone colloid was very fast at the initial time,while the dehydration degree was higher at higher curing temperatures,especially at 105~130℃. The absorbtion peak appeared at 1728.9cm-1 is attributed to the acetyl group due to the isomerization of oxirane in KH-560.
