Solution for the electric vehicle frame electrophoresis paint
Product Introduction:
HL-1607LB/HL-1530G 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.
suchas: coldandhotrolledsteelsheet,galvanizedsteel sheetandstainless steelsheetetc.
This product features shown below:
| The appearance of the coating is flat, delicate, smooth, uniform high gloss. |
| Excellent leveling coating,good bonding for ceand compatibility with plastic powder. |
The main component Matrix resin:
1, Neutralizing agent: organic acid
2, Solvent: alcohol ether
3, Pigment: carbon black, kaolin, antirust pigment
4, Curing agent: Fully enclosed multi isocyanate
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:
