VERFAHREN ZUM BESCHICHTEN ELEKTRISCH LEITFAEHIGER SUBSTRATE, WAESSRIGER LACK, EPOXID-AMINADDUKT UND VERWENDUNG DES EPOXID-AMINADDUKTES ALS REIBHARZ ZUR HERSTELLUNG VON PIGMENTPASTEN |
摘要 |
The resistance of automobile enamels to impact from stones is increased by the use of aqueous electrophoretic enamels prepared from a pigment paste containing a friction resin in the form of epoxide amine adduct which is at least partially protonized. The epoxide amine adduct is obtained by reacting (A) a glycidyl ether of a polyphenol which, on a statistical average, contains at least one epoxide group per molecule, or a mixture of such glycidyl ethers, (B) a polyglycidyl ether of a polyol which, on a statistical average, contains more than 1.0 epoxide group per molecule, or a mixture of such polyglycidyl ethers, (C) a compound which contains one primary amino group per molecule or a mixture of such compounds, in a stoichiometric ratio such that, on a statistical average, at least 2.0 primary amino groups of the constituent (C) are incorporated in the epoxide amine adduct obtained, forming chain-lengthening tertiary amino groups, and the epoxyde amine adduct obtained is at least partially protonized.
