Zinc Phosphating

Zinc phosphating is also well know as 7 tank process.

A high-quality conversion coating is essential for the durability of painted metal goods. The process of applying an inorganic conversion coating(phosphate) to a metallic surface involves removing any surface contaminants, then chemically converting the clean surface into a non-conductive, inorganic conversion coating. Conversion coatings increase the overall surface area and promote adhesion of the subsequently applied paint. In addition, conversion coatings change the chemical nature of the surface(It Forms zinc phosphate or iron phosphate) which increases corrosion resistance. It is these two functions, increasing surface area and changing the surface chemistry, that serve as a base for preparing the substrate material for paint finishes.

The process of Phosphating basically relies on the basic pickling reaction that will occur on the metal substrate if the process solution will come in contact with metal. The biggest benefit that Phosphating can give is corrosion protection and strong adhesion. Just like Phosphate Coating, the process of Phosphating is being used for steel parts.

 

Emulsified Degreasers

Metrite Emulsified degreaser is a phosphoric acid based water soluble emulsified, room temperature degreaser.

It contains surfactants and solvents designed to remove soil, heavy oils and carbonaceous deposits at ambient temperature. It removes toughest grease deposits and is ideal for replacement of alkaline degreasers used in seven stage phosphating of MS articles. Chemical is widely used for the pretreatment of air conditioner cabinets, control panels, refrigerators etc. And degreasing of articles before electroplating and aluminium Chromatising.

Our emulsified degreasers can also be used in process with our Descalers to remove scale of HRCA material in a very effective manner.

Higher concentration and longer immersion time may be required if contaminants to be removed are very heavy, dry oil film etc.

 

Chromatising

Chromatising (chromate conversion coating) Chromatising is used to chemically convert the surface of the aluminium product. This results in a thin oxide layer, what is referred to as a conversion layer, which offers protection. During the chromatising,  a surface layer results which varies in colour from white to gold/brown iridescent. Chromatising is often applied as a coating pre-treatment as it provides high-quality adhesion and excellent protection against corrosion. Moreover, it is often prescribed locally for facings or for electrical conductivity.

Characteristics

• Electrical conducting coating.
• Effective protection against oxidation in the case of products applied internally in machines.
• As a result of the excellent adhesive characteristics, chromating is a suitable pre-treatment for further coating processes.
