Binders for use in cathodic electrodeposition coatings, process for their preparation and cathodic electrodeposition coating compositions containing same |
摘要 |
<p>Novel alkaline polymeric binders, preferably amino epoxy binders, for use in cathodic electrodeposition coatings have a number average molecular mass of 1000 to 3000, an amine value of 150 to 250 mg KOH/g binder and 50 to 230 milliequivalents/100 g binder of beta-hydroxyalkyl urethane groups of the formula HOCnH2nOC(O)NH- where n = 2 to 3, as well as processes for making such binders; aqueous compositions, particularly cathodic electrodeposition compositions containing such binders (which provide improved throwing power); and process of using such compositions, particularly on automotive bodies and parts thereof, are disclosed.</p> |
