Solution for pump electrophoretic paint
Product Introduction :
HL-1605LB/HL-1701A Black 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 coatingthat isenvironment-friendly withhigh propertyandlow cost. Such coatingdoesnot 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, andcan adapt galvanized steel sheet perfectly,almost canbe 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 stain less steel sheet etc.
This product features shown below :
| The appearance of the coatingis flat,delicate,smooth | Good stability of bath can adaptable for a longer updating cycle |
| Strong anti-corrosion properties, good salt spray resistance workpiece edge | Excellent leveling coating,good bonding for ceand compatibility with plastic powder |
The main component Matrix resin:
1,Additives: surface active agent, prevent shrinkage cavity agent
2,Pigment: Titanium pigment, carbon black, kaolin, antirust pigment
3,Curing agent: totally enclosed multi-isocyanates
4,Matrix resin:polyurethane modified epoxy resin
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 see the table below for reference:
