High solid alkyd polymers based on soya have been developed

Tuesday, 9 February 2010

Air-drying high solid coatings meeting the requirement of low VOC have been successfully synthtesised at 80 % solids.

A series of high solid alkyd polymers from soya and dehydrated castor oil fatty acid (SOFA and DCOFA) combination with varying percentage of Dipentaerythritol (DPE) have been synthesised and characterised for their physico chemical, optical, thermal and mechanical properties. Results of 500 hours of QUV exposure revealed higher gloss retention for DP based systems. When compared for the anticorrosive properties, the EIS spectrum reveals that alkyd film containing 100 % DPE has the higher value of impedance. You can read more about the different properties in the November issue of Paint India, pages 61-74.
