"PU lacquer was tarnished by vulcanization"



July 6, 2016

Q. Hello Sir,

I'm working in an accessory garment company which is facing a big problem with lacquering on brass zippers. We are using 2-part PU lacquer to finish our product which be required polished and protection from corrosive. Our customers sewed the brass zippers on shoes then it was vulcanized for 90 mins, 120 °C. Hence the zippers were tarnished.

I'm trying to use another lacquer ( Nitrocellulose ) to solve it but I need some advice which one is suitable with our process to protect the bright brass surface and chemical coating surface (patina, Tin, oxidation coating, etc.)

I greatly appreciate your advice. Thank you!
