TWO-PACKAGE POLYMERIC EPOXY COMPOSITIONS HAVING IMPROVED POTLIFE |
摘要 |
<p>Two-package polymeric compositions which form cured products having excellent stain and solvent resistance and having improved potlife comprise a polyepoxide and an addition interpolymer containing pendent salt groups formed by reacting carboxyl groups with a hindered amine and pendent amine groups formed by reacting carboxyl groups with an alkylenimine. The addition interpolymer when mixed with the polyepoxide reacts to form a cured, hard, stain and solvent resistant material. The stability of the mixed compositions, i.e., its potlife, is lengthened by utilizing a sterically-hindered tertiary amine to form the salt groups of the interpolymer. Stability of the addition interpolymer prior to mixing is improved by utilizing therein monomers which provide aminolysis-resistant groups in the interpolymer.</p> |
