Synthesis and Application of Silicon-Alkyds in Stoving Paint and Zinc-Rich Primers

Alkyd resins which are used in the organic coating industry have various properties with different applications which include flexibility, resistance to stroke, high adhesion property and resistance to breakage. Nevertheless, it has some shortcomings as well, which should be removed by combination of other resins and polymers. One of the properties which need correction is weak thermal properties that can be removed by combining with silicon resins. In the present study manner of preparing silicon - alkyd copolymer, it’s properties, specifications and it’s thermal application range have been explained. Thermalresistance of alkyd based coating is improved with silicone effect in resin and flexibility of ethyl silicate primer increased by alkyd effect in silicon modified resin. Silicone-alkyd based of primer is comparable with ethyl silicate primer in mechanical properties and has lower price. J. Color Sci.
