Article's abstract:

An improved aqueous electrocoating composition containing an anticrater additive which is a reaction product of silane component based on glycidoxy propyl tri methoxysilane and poly oxy propylene diamine. Materials were studied by infrared spectroscopy and particle size analyzer. Crater number of electrocoated sample was evaluated by GM9532p standard. The final electrocoat contains anticrater agent produces coating having a smoother appearance with fewer craters.
