Electrophoretic Polyurethane Coating Required
Q. We are looking for an electrophoretic polyurethane coating system that is UV resistant.
It should be able to be dyed brass, gold, copper etc.
I have heard they exist with very good UV resistance and after approval testing, we would be looking to use large quantities of chemicals.
Polyurethane is chosen from advice, but please correct us if we have been mislead.
The coating should be flexible and suitable for a 10 micron application.

PU lacquer was tarnished by vulcanization

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!
