High weatherability electrophoretic paint for engineering machinery
Product Introduction :
HR-4000LB/HR-4010 Epoxy acrylic Gray Cationic Electrocoat is HLS
Paint (Shanghai) Co., Ltd., the eighth generation of independent
research and development of electrophoretic coating.
This coating by epoxy acrylate modified, the film also has
excellent corrosion resistance and weatherability, smooth
appearance and full, suitable as a base topcoat system. In
addition, the lead, cadmium, chromium, mercury and other heavy
metals, two-component, water dispersible resin, at the same time,
previous generations of the product characteristics, have good
adaptability to the galvanized steel, almost can be applied to all
metal coating
such as: cold hot rolled steel, galvanized steel, aluminum, zinc
Aluminum Alloy plate, stainless steel plate
This product features shown below :
Good stability of bath can adaptable for a longer updating cycle
| High penetration and good uniformity of internal and external. | Good weather resistance, very suitable for car body, car chassis,
electric, three wheeled motorcycle frame and other industries. |
The main component Matrix resin :
1,Matrix resin: Acrylic modified epoxy resin
2,Neutralizing agent: organic acid
3,Additives: surface active agent, prevent shrinkage cavity agent
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
