摘要： A method of preventing the yellowing of the outermost coating of a multicoat coating system is disclosed. The method comprises initially depositing onto a conductive substrate by cathodic electrodeposition a primer coating comprising at least one layer of an amine-epoxy resin adduct and a cross-linking agent, and then curing said primer to a hard, durable film. Then, depositing a second coating onto the primer layer comprising at least one layer of a pigmented film-forming basecoat. Then depositing a third outermost coating onto the second coating comprising at least one layer of a clear, film-forming topcoat, and then curing the basecoat and topcoat. The primer coating contains a cross-linking agent selected from the group consisting of aliphatic polyisocyanates containing at least six carbon atoms, the isocyanurates of aliphatic polyisocyanates containing at least six carbon atoms, aromatic polyisocyanates having a molecular weight greater than 174, and the isocyanurates of aromatic diisocyanates having a molecular weight greater than 174. The polyisocyanates or isocyanurates are blocked with a blocking agent.

摘要： 0 Mechanical stability and coating characteristics of structurally cation-active, film-forming latex, especially useful in electrodeposition coatings can be improved by the addition of small stabilizing amount of linear cationic amine-modified epoxy resin having tertiary amine functionality and base number in the range of 30-500 and/or glycol mono-substitut ed ether alcohols. "Stability" is defined by the absences of agglomerated latex particles as shown by disc centrifuge photosedimentometer traces after subjecting the latex to 30 minutes of mechanical shear using a Hamilton Beach mixer. Such stabilized latex remains substantially non-agglomerated even after being subjected to pumping and shear. Without the stabilizer, agglomeration of the latex occurs.
摘要翻译：特别可用于电沉积涂层的结构阳离子活性成膜胶乳的机械稳定性和涂层特性可以通过加入小稳定量的具有叔胺官能度和碱值的线性阳离子胺改性环氧树脂在 30-500和/或二醇单取代醚醇。通过使用Hamilton Beach混合器对胶乳进行30分钟的机械剪切后，通过圆盘离心机光刻仪痕迹所示，聚集胶乳颗粒的缺失限定了“稳定性”。即使经过泵送和剪切之后，这种稳定的胶乳仍然基本上不凝聚。没有稳定剂，胶乳发生凝聚。

摘要： Cathodic electrodepositable resin compositions and aqueous electrodeposition coating baths comprising these resins are disclosed. The resin compositions comprise a cationic amine epoxy resin adducts and a cationic polyurethane resin adduct dispersion. The resin compositions when combined with a cross-linking agent and cathodically electrodeposited produce films which cure to durable, flexible, smooth corrosion-resistant, impact and chip-resistant films.

摘要： Oxime blocked polyisocyanate cross-linking agents for use with nitrogen containing epoxy resins in cathodic electrodeposition processes. The oxime blocking agents are the reaction products of carbonyl-containing compounds having at least 4 carbon atoms and hydroxylamine. The oxime blocked polyisocyanates produce cathodic electrodeposited coatings which are smoother than coatings produced by oxime blocked polyisocyanates known in the art.
