Coating pretreatment / lubrication type phosphating


High-quality paint, electrostatic powder and electrophoretic coating cannot be separated from high-quality pretreatment.Modern coating more emphasis on environmental protection, energy efficiency and other production costs and social environment-friendly indicators of painting pre-treatment chemicals. WECAN provides the most comprehensive cleaning and conversion film products for plastics, steel, stainless steel, aluminum alloy, magnesium alloy and zinc alloy, so that the coating is more firmly combined with the workpiece to prevent corrosion under the coating and prolong the service life, realizing continued add-value for your products.

Zinc Phosphating is a modified ternary low zinc phosphating process agent that can be used for phosphating treatment of steel plates and galvanized sheets. The dense phosphating film crystals are excellent in paint, powder coating and electrophoresis processes to meet the processing requirements of automobile body and various components.

Electrolification
It is an electroless phosphating product that does not contain heavy metals and is suitable for wire production processes that require cold forming, meaning, phosphating while online drawing. Steel wire substrate can be high, low carbon steel wire, fastener wire, or stainless steel wire.

The thickness of the phosphating film can be precisely adjusted by the strength of the current and the processing time.
