Overview

In the present study, vinyltrimethoxysilane was used to modify high-ortho novolac resin (NR) to obtain a vinyl silicone-modified phenolic oligomer (Si-mod NR). Subsequently, this oligomer is polymerized with methyl methacrylate. The mid-products (NR and Si-mod NR) and synthesized silicone-modified phenolic/acrylic resin (Ac/Si-mod NR) were characterized by Fourier transform infrared spectroscopy, and thermal properties were investigated by using thermal gravimetric analysis and differential scanning calorimetry techniques. In addition, the surface coating properties, including drying, hardness, adhesion, impact resistance, gloss, acid, alkaline, water, and solvent resistance of the films prepared from these products, were comparatively investigated. The results showed that the modification reactions yield a novel resin (Ac/Si-mod NR), which can be easily used as a surface coating material with high thermal resistance, flexibility, and excellent film properties.
