| Résumé : |
Interpenetrating polymer networks (IPN) are novel types of polymer blends and they possess excellent physicochemical properties suitable for high performance coatings. In the present work a novel siliconized-epoxy coating system was developed by interpenetrating technique. The effect of siloxane introduction into epoxy resin and nature of curatives on the corrosion resistance characteristics towards steel specimen were studied by weight loss and electrochemical potential measurements. It was observed that, the siloxane incorporation enhances the corrosion resistant properties and reduce moisture absorption. It was also observed that the aromatic polyamineadduct cured siloxane modified epoxy coating system with 25% zinc powder exhibits better corrosion resistance than the polyamidoamine cured system. |

- Status quo
- Siloxane polymeric component is suitable to modify epoxy resin
- Experimental: - Surface preparation of test specimen - Preparation of siloxane modified epoxy coating system - Preparation of prepolymer mix - Siloxane introduction into epoxy coating system - Application of coating over test specimen - Weight loss method - Calculation of weight loss a raw specimen (x) - Electrochemical potential measurement
- Minimum weight loss and maximum corrosion protection with siloxane modified epoxy
- Cured by aromatic polyamineadduct better than polyamidoamine cured system
- Incorporation of siloxane as well as zinc powder enhances corrosion protection behaviour
- Aromatic nature of the curative minimizes the oxidation of steel specimen |
