IATF16949 Protective Auto Parts ED Painting Corrosion Resistance

Passenger cars and commercial vehicles seat Black electrophoresis paint

Product Introduction:

 HL-1607LB/HLS-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 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 and stainless steel sheet etc.

This product features shown below:

The appearance of the coating is flat, delicate, smooth, uniform high gloss. 

Good stability of bath can adaptable for a longer updating cycle. 

The bath has strong anti-shrinkage and anti-pollution ability. 

Strong anti-corrosion properties, good salt spray resistance workpiece edge.



Coating fullness of good, better substrate hiding . 

The main component Matrix resin:

polyurethane modified epoxy resin

Curing agent: totally enclosed multi-isocyanates

Neutralizing agent: organic acid

Solvent: alcohol ether

Additives: surface active agent, prevent shrinkage cavity agent

Pigment: Titanium pigment, carbon black, kaolin, antirust pigment

Product quality data:

Note: pH, conductivity measurement in the resin/pure water = 1:1 dilution

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:

Product film performance:

* Note: The substrate use the Bonder standard phosphating steel panel, crossed out unidirectional expansion eclipse ≤ 2mm.

Construction equipment:

Cathodic electrophoretic coating construction in the electrophoresis tank, so need to have the following equipment: 

Electrophoresis tank 

Circulation devices (including filter, fill the paint device) 

DI water equipment 

DC power supply and the power supply unit 

Anode box (tube) and circulation device 

Ultrafiltration device 

Cleaning devices 

Heat exchanging equipment 

Curing device
 

Storage, packaging and transportation:

This product is a water-borne industrial coatings, non-hazardous, non-inflammable and explosive products; transportation to prevent direct sunlight, avoid freezing (>5℃ ); Packaging for 50/60/200L Plastic barrel; in the transport and storage of drums should be maintained clean, avoid charging the dirt brought in on drums during filling tank, again checked and confirmed that the quality of products, including paste resin, emulsions and additives should be indoor storage, good ventilation, dry, protect against freezing and overheating, the storage temperature should be controlled at 5～35℃, products from the date of production, over shelf, experimentation is required to determine whether can continue to use.

Specification statement:

This manual contains information and recommendations are based on our current knowledge and experience, accurate to the date of publication so far. It cannot be used as a guarantee or commitment, in any case, responsibility for users to decide on the use of this product is intended availability. We remain in the process or new development within the scope of the right to change product specifications. Because we cannot control the construction conditions, hope through customers own experiments to determine satisfaction with the final results.
