MANUFACTURE OF WATER-DILUTABLE RESIN, RESIN MANUFACTURED THEREBY AND USE TO THERMOSETTING SURFACE COATING |
摘要 |
<p>Resinous compounds suitable for aqueous thermosetting coating dispersions or solutions after neutralization, are prepared by reacting a diglycidyl ether of a dihydric phenol with a hydroxyalkane monocarboxylic acid and dimerized unsaturated fatty acids, with epoxy equal to or in slight excess over carboxyl, below 150 DEG C. in the presence of an epoxy/carboxyl esterification catalyst to produce a non-acidic intermediate, and then reacting the intermediate at a temperature below 150 DEG C. with a polycarboxylic acid anhydride in amounts to provide an acid value from 5 to 35. Aqueous dispersions are prepared by at least 50% neutralization of such compounds having acid value 5-15.</p> |
