摘要： 1 Process for producing a catalyst paste for cathodically separable electrophoretic dipping lacquers.2.1 Use was made of dibutyltin oxide by way of a catalyst paste for electrophoretic dipping lacquers, dispersed in pasting binders. An object is to provide a new process for producing such catalyst pastes while saving time and energy.2.2 A process is provided for producing a catalyst paste for cathodically separable electrophoretic dipping lacquers, wherein the dibutyltin oxide is first pre-dispersed with an organic solvent and an organic acid such as is commonly used for neutralizing cathodically separable electrophoretic dipping lacquers, whereupon it is dispersed with the pasting binder and water and ground.2.3 Cathodic electrophoretic dip lacquering making use of catalyst pastes containing dibutyltin oxide.

摘要： Cathodic electrodeposition coating compositions containing, in addition to conventional self-cross-linking or external cross-linking film-forming binders as well as optionally cross-linking agents, pigments, extenders, additives conventionally used in coating agents and solvents, from 0.1 to 5 wt-%, based on the resin solids content of the coating compositions, of one or more sulphonamides, when coated on a galvanized surface, produce coatings that are substantially free of pinholes.
摘要翻译：阴极电沉积涂料组合物除了常规的自交联或外部交联成膜粘合剂以及任选的交联剂，颜料，增量剂，常规用于涂料和溶剂中的添加剂中还含有0.1至5 当涂覆在镀锌表面上时，基于涂料组合物的树脂固体含量，一种或多种磺酰胺的重量百分比产生基本上没有针孔的涂层。
