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.

树脂稳定剂,可改善阳离子活性成膜胶乳(尤其适用于电沉积涂料)的机械稳定性和涂料特性。"稳定性 "的定义是在使用 Hamilton Beach 搅拌器对胶乳进行 30 分钟的机械剪切后,圆盘离心机光沉降仪显示的胶乳颗粒不团聚。这种经过稳定的胶乳即使在经过泵送和剪切后也基本上不会结块。如果不使用稳定剂,胶乳就会结块。
