METHOD OF PREPARING CASTING AND COATING COMPOSITIONS USING POLYOLS DERIVED FROM HIGH OLEIC ACID CONTENT FATTY ACID MIXTURES

摘要

Polyols which can be obtained by making epoxidized fatty acid esters of monofunctional C 1-8 alcohols react with aliphatic alcohols having a functionality ranging from 2-10. Fatty acid mixtures with mainly 18 carbon atoms represent the fatty acid component in the epoxidized fatty acid esters. The oleic acid content of the fatty acid mixtures is at least 80 wt %. The polyols are suitable for use in the production of isocyanate casting resins and coating compounds with enhanced colour stability.
