Metal Pretreatment Chemicals

We are offering Metal Pretreatment Chemicals. Metal Pretreatment Chemicals, available with us, are made with accurate formulation of various chemicals. The Metal Pretreatment Chemicals are known for showing excellent results. Various kinds of Metal Pretreatment Chemicals can be availed from us.  
 
Nano pretreatment/conversion coating chemicals products
Nano coating is a dramatic improvement in ecological as well as in economics. These processes are free of heavy metals, such as nickel, magnesium and zinc subject to restriction in the field of worker safety or waste disposal. It can be coated to all type of metals, like steel, aluminum, zinc and its alloys, magnesium substrate, etc
Advantages of Nano coating

• It forms very low sludge, and hence it reduce waste disposal, cleaning and maintenance

 

• It can be operated in ambient temperature

 

• It also reduce process time significantly

 

• It penetrates deeply in to the surface, and hence the coating will give good paint adhesion

 

• It eliminates passivation step, therefore it reduce process time and cost

This pretreatment is suitable for all conventions powder and wet paint coating. It creates an inorganic, extremely high density layer incorporating nano particles. It results in a conversion layer on the order of nanometer thick, whereas phosphate coat gives in the order of microns thick.
Chemicals available for both dip and spray mode of application
Chromatizing chemicals for aluminum surface
Chromating, or chromate conversion coatings, are extremely thin chemical coatings that provide a couple of desirable characteristics to the surface of aluminum and zinc parts such as :

• Enhanced corrosion resistance

 

• Enhanced bonding ability

 

• Electrically conductive

Alchrom
Alchrom is a chromating chemical for aluminum surface and its alloy components. The coating can be painted or left unpainted, as required. Alchrom coating are integral with the metal and will withstand bending and denting of the surface.

• Yellow chrome oxide coating

 

• Greenish yellow chrome phosphate coatings

 

• Colorless chrome oxide coating

 

• Trivalent chrome oxide coating for aluminum surface

Zinchrome
Zinchrome is a chromate conversion coatings for zinc & its alloys and zinc plated components.
Oxidizing salts - blackening and bluing chemicals
The oxide coatings are in fact corrosion products, which are thin, usually less than 2.5 µm (.00001 in) oxide with good adhesion.
 
Advantages Of Conversion Coating

• No dimensional changes

 

• The finish will not chip, peel, flake, or rub off

 

• Reduces light glare (reflection)

 

• Improved lubrication characteristics

 

• It make excellent finished surface for moving parts, such as hand tools and machine parts

 

• Blackening chemicals

 

• Bluing chemicals

Passivation chemicals
In order to obtain maximum corrosion resistance over phosphate coatings, it is necessary to apply a post-treatment in order to seal the parts.
Evercure
It is a passivating chemical for pickled surface. It produces passivating film on derusted surface of iron and steel. It protects iron and steel from rusting in-between surface.
Everfix
Everfix is a passivating chemical for painting surface. In order to obtain maximum corrosion resistance over phosphate coatings, it is necessary to apply a post-treatment in order to seal the parts.

• Chrome passivation

 

• Non-chrome passivation

Surface conditioners
Surfine-surface activation chemicals
Surfine is an additive to additional rinse tank prior to phosphate coating. Surfine bath treatment gives neutralization and grain refiner in derusted surface. Surfine is available for both zinc and manganese phosphating process.
Neutralizer
Neutralizer chemicals are perfect for acidic and alkaline surface. They protect derusted surface of iron and steel.
