Mild Steel & Galvanised Steel

We formulate and manufacture high quality speciality chemicals for the treatment of Mild Steel and Galvanised Steel, to ensure you get the best finish possible.

Derusters & Descalers

Effective for derusting iron and steel before phosphating or descaling to remove any oil, grease, dust and carbon deposits from the surface of aluminum die cast without effecting the base metal.

Cleaners and Degreasers

We formulate and manufacture acid, alkaline and neutral Cleaners and Degreasers for etching and desmutting. They come in the form of liquid and powder or for spraying and immersion. They are for low temperature and low concentration operation.  Cleaners and Degreasers are so very effective as when applied to grease stains, they chemically react with the grease particles and produce a deep clean.

Benefits of using cleaners and degreasers include a simple application, with a variety of applications for all different surfaces. Degreasers are designed to work quickly and be cost-effective, they are highly affordable and we can supply in bulk.


Water Treatment Products
Mild Steel Treatment

Phosphating Processes

  • For Corrosion Protection: class 1 Iron-non-rinsing, heavy manganese, heavy weight zinc, light weight zinc
  • For Paint Bonding: tricationic zinc, calcium modified zinc, high coating weight amorphous iron, light weight amorphous iron, multi-metal cleaner / coaters, low temperature operation.

Dewatering Oils

Dry to touch, pre paint, and temporary protection

Specialised Rinse Additives

Chromate and non-chromate formulations

Chrome Free Conversion Processes

For aluminium and galvanised steel

Film Forming Processes

Chrome polymer resin, non-rinse, low film thickness, and film-forming processes.

In the film formation process, a low-viscosity liquid surface coating is applied to a solid substrate. After curing this surface, it produces a solid, high molecular weight, polymer-based adherent film. This film protects a substrate from the attack of corrosive substances as well as corrosion.

Features of our film forming resin: low film thickness, various coating applications, protects the surface of the material from the environment.

Laser Cut Edge Oxide Scale Removal

Combined degreasing, phosphating and elimination of poor paint adhesion on the cut laser edge.

 Titanium-Zirconium Technology

Gives the corrosion performance of traditional zinc phosphates and chromates on aluminium without the problems associated with effluent treatment.

Chromating Processes

Traditional well proven chromate systems for the pre-treatment of window frames, curtain walling etc. Approved by all major powder coating manufacturers. For galvanised steel and aluminium.
