The physical, mechanical and thermal analysis on methoxy functional silicone intermediate resin blending with acrylic polyol resin
Silicone modified acrylic polymer dispersion was prepared by blending methoxy functional silicone intermediate resin with acrylic polyol resin in different ratios. The physical, mechanical and thermal properties were investigated. The physical property of the blend has been carried out by using Kruss G40 contact angle measuring system, mechanical property of the blend evaluated by using impact resistance tester and adhesion tester (Cross Hatch- Cutter) and thermal analysis has been carried out by using Metler Toledo thermal analysis system DSC821. It is found that the incorporation of 50% silicone resin with 50% acrylic resin gives good adhesion on metal substrate (mild steel substrate) and optimal cross-linking is achieved.
