Q. We manufacture zippers with zinc die cast components. after painting with epoxy, when the zippers attached to the clothes like skirts, cushion covers, etc.. are subjected to domestic laundry, washing process, paint chipping off happens and runnability of pullers also suffers. Can any one suggest a better way or improve the resistance of epoxy paints on zinc die cast components

A. Hi, KP. Proper phosphatization and electrocoat priming would probably go a long way. But I don't know the clothing industry, and am surprised to find out that zinc zippers can survive multiple washing cycles; I assumed they were brass.
