Abstract

The influence of high temperature baking on the application performance of silicone modified acrylic resin coatings film was discussed.Through the test verification,it was found that different silicone modified acrylic resin coatings performance presented a great difference in weatherability.The water-based silicone modified acrylic resin was prepared by siloxane monomer,vinyl siloxane,methyl trichlorosilane,polyvinyl siloxane and polydimethyl siloxane respectively.The results showed that the sequence of baking resistance of silicone modified acrylic coatings was polyvinyl siloxane=polydimethyl siloxane > vinyl siloxane > methyl trichlorosilane > siloxane monomer.

Key words
