Method of producing epoxy esters. |
摘要 |
<p>Epoxy esters having reduced viscosity and which are curable with aminoplast resins to produce water insensitive coatings are disclosed along with a method of producing them. In this method an organic solvent solution containing a 1% to 20% stoichiometric excess of polyepoxide at least 60% of which is constituted by diglycidyl ethers of a bisphenol having an average molecular weight of less than 500 and a 1,2-epoxy equivalency of from 1.8 to 2.0 is slowly added to a mixture of fatty C6-C22 monocarboxylic acid and esterification catalyst maintained at elevated reaction temperature under conditions appropriate for the reaction of 1,2-oxirane with carboxyl, and the reaction conditions are maintained until the acid number is less than 10.</p> |
