Abstract

The hard coatings on the polycarbonate plate were performed with the object of substitution the glass in the car to the polycarbonate plate. In this research, (3-glycidoxypropyl)trimethoxysilane (GPTMS), (3-aminopropyl)triethoxysilane (APS), and diethylenetriamine (DETA) were used to prepare the coatings by a sol-gel process. The optimum conditions and formulation to achiere the excellent physical properties of the coating were determined. In the case of using GPTMS and DETA, the smooth coating which had the 2 H class in pencil hardness was formed. In the case of using GPTMS and APS, the coating which had the 2 H class in pencil hardness was also formed. And the coatings with GPTMS and DETA showed an excellent abrasion resistant.
