Solution for the Car doors electrophoresis paint.
Product Introduction
HS-6060LB/HS-2568G Gray Cationic Epoxy Electrocoat for auto is a
new generation electrophoretic coating researched and developed by
HLS Paint (Shanghai) Co., Ltd. It represents modern technology of
cathodic electrophoretic coating that is environment-friendly with
high property and low cost. Such coating does not contain heavy
metal like lead, tin, cadmium and mercury etc. It is a
two-component, water-dispersed resin,meanwhile, it took in features
of previous products, and can adapt galvanized steel sheet
perfectly, almost can be applied to foundation coating of all
metal, such as: cold and hot rolled steel sheet, galvanized steel
sheet, aluminum products, zinc-aluminum alloy sheet and stainless
steel sheet etc.

Bath on site management project
Good bath data and coating quality, from the strict parameters
management and maintenance of equipment, production line according
to its own reality time situation, can have different management
project and specifications, recommend the construction parameters
