Research on Application of Nano-TiO₂ in Automotive Coating

Abstract:

In this article, the mechanism of the effects of nano-TiO₂ on the properties of automotive topcoat is discussed. Based on the original thought that nano-TiO₂ may improve the aging property, a research is carried out into the effects of nano-TiO₂ on the properties of automotive topcoat, and the formulation design of nano-TiO₂ coating is optimized. The coating properties such as glossiness, adhesion, resisting impact strength, hardness, water fastness and resistance to aging are measured by experiments. The results show that with 1.0~2.0 percent of nano-TiO₂ content, the aging resistance of the coating increases by approxima_{Subscript text}tely 20 percent with higher glossiness, while adhesion, impact strength, hardness and water fastness are not meaningfully improved.
