Overview of Surface Treatment Chemicals

Surface Treatment Process means removal of oil, grease, rust, heat treatment scale, and welding scale from metal surface using chemicals. Then application of conversion coating, before painting, powder coating, Rubber to metal bonding and rust preventive application.

Our surface treatment chemical process is easy to operate, operator friendly, consistency in quality environment friendly operate at lower temperature, hence cost and energy saving. All Phosphating chemical passing IS-3618 standards.

Degreasing Chemicals

The First step is De-greasing i.e. removal of dirt, oil, and grease from metal surface by wiping, spraying and dipping. The nature of chemicals to be used depends upon the base metal and oil grease present on surface.

  • Lower alkaline degreasing chemical AK-15/ AK-14
    • Caustic free, lower alkaline powder excellent combination of alkaline builders, water softners solvent and surfactant.
    • Remove soil, grease, from metal surface effectively at 50-60 0C
    • Mainly used in powder coating pre-treatment process because of lower alkalinity carrier over to next bath is low (life of water rise bath increased.)

    • Phosphoric, sulphuric acid, surfactant and solvent unique combination for removal oil, rust, scale, smut from metal surface at room temperature.
    • This cleaner used in powder coating and electroplating. Sometimes, use of only acidic cleaner is sufficient for removal oil and rust for heavy oil and rust must alkaline degreasing chemical and derusting chemicals.
Available in 30 KgHDPF drums.
  • Emulsion cleaner
    • Emulsion cleaner are generally based on either kerosene- emulsifier??
    • Emulsion cleaner is always followed by alkaline cleaner.
    • Almost oil type of oils can be removed by combination of emulsion and alkaline cleaner.
Available in 20 Kg HDPE drums.

Derusting Chemicals

The second step is De-rusting i.e. removal of rust, heat treatment scale, welding scale from the surface. The nature of chemicals to be used depends upon the base metal and oil grease present on surface.

  • AK-DR-31M
    • Mixture of Acid’s Acid Inhibitor Effectively remove rust heat treatment and welding scale from metal surface.
    • Add 10-30% chemical in water at ambient temperature to 60 0C for effective removal of heavy rust and scale.
    • It is used in powder coating for steel component.
Available in 30 Kg HDPE drums.
  • 3IN 1 chemical
    • Several types of 3 in 1 chemical
    • Used in powder coating for removal of oil, rust, scale from steel and iron Phosphating layer form on surface which provide good surface for painting and powder coating
Available in 25kg HDPF drums.
  • Aletch:- [ AK-ALCH-155 / AK-ALCH-154, AK-ALCH-153]
    • Excellent combination of acid, surfactant, and inhibitor solvent
    • Effectively remover smut and oil from Aluminium surface provide very good surface for chromating and anodizing which help painting, powder coating and rubber to metal bounding.
Available in 25kg HDPF drums.

Activation

The third step Activation i.e. activation of metal surface which will help application of conversion coating in short time.

  • Acidic activation :-[AK-34]
    • AK-34 is acidic activation one minutes processing in AK-34 bath prior to Phosphating help in producing smooth & fine crystalline zinc phosphate coating this also reduces processing time.
Available in 5 kg HDPE bags.
  • Alkaline titanic activation :- [AK-35]
    • AK-35 is titanium modified activation salt used prior to Phosphating. It help in producing smooth, dense & fine crystalline zinc phosphate coating on iron, steel and galvanize steel, this also reduces processing time and improve corrosion resistance. It can be applied by dipping and spray.
Available in 5 kg HDPE bags

Phosphating Chemicals

The next step is Phosphating i.e. Conversion coating chemicals are applied on metal surface to provide corrosion protection, promote good adhesion, gives under paint corrosion protection, adhesion for rubber to metal bonding.
