Metal Treatment Chemicals

Phosphating can be regarded as a process of coating a ferrous metal surface with a passive phosphate coating for the prevention of rusting of metal. Phosphating are primarily of two types:- 

• Iron Phosphating - Blackish Color Coating
• Zinc Phosphating - Whitish Color Coating

Chemtex Speciality Limited manufactured product Phosphating Chemicals are used to perform three functions:

• Degreasing
• Derusting
• Phosphating

The Phosphating Chemical for mild steel (crc sheets), cast iron are especially formulated for removal of oil, grease, rust and simultaneously for producing a thin iron phosphate or zinc phosphate coating on the metal surface to avoid further corrosion or rusting.

Chemtex offered product Phosphating Chemical can effectively be used as line deruster and in-process cleaner prior to painting or any other similar metal treatment operations.

Key Features and Benefits:

• Self Curing
• Acts effectively at room temperature
• Extends the life of metal

An acid neutralizer is used to help maintain the pH balance in many water systems.
Acid Neutralizers raise the pH of acidic water to neutralize its acidic/ corrosive characteristics. It is a highly concentrated alkaline tailored to render acidic wash/rinse solutions safe for discharge. This detergent consistently meets the critical standards for the cleaning of goods commonly processed in sterile departments. 

Chemtex’s Metal Finishing Chemicals consist of a whole range of Pickling Inhibitors and Metal Phosphating.

Acid Pickling Inhibitor is a strong foaming inhibitor for use batch pickling method for all kinds of steel and alloys at any concentration.

Metal Surface Treatment Chemicals can be of vital significance in numerous commercial enterprises. Today there can be a few reasons why it is important to change the surface properties of metals. For instance is surface treatment of metals utilized for:

• Beautification
• Enhanced hardness (eg. for imperviousness to wear and tear)
• Anti Corrosion
• Expanding life of metals

There are a few sorts of surface treatment as a part of the surface treatment process.
• Covering with Oxides: Coatings done by the assistance of oxides are generally corrosion products. These treatments are typically done through electrochemical reactions, heat, or chemicals.
• Chromate Covering: Chromate coatings can be connected on cadmium, zinc, magnesium and aluminum as a result of their resistance towards climatic consumption. These coatings are widely utilized for protecting household items.
• Phosphate Covering: Generally, phosphate coatings are connected on cast iron, low-combination steel and carbon steel.

However, it can be coated on cadmium, tin, aluminum and zinc as well.

Chemtex manufactures a wide range of Metal Surface Treatment Chemicals that modifies the metal surface for better surface finish such as derusting, phosphating and passivation. Various procedures are there for the metal surface treatment. Metal surface treatment involving Metal Surface Treatment Chemicals, is a process where metal parts to be painted are prepared. Coatings Pretreatment is the name commonly referred for preparation. The preparation involves creating a barrier for protecting the metal against corrosive environment. For creating a proper metal surface treatment, the Metal Surface Treatment Chemicals or film must impart equal potential to the surface and neutralize the possible anodic and cathodic corrosion areas so that it can provide an absorptive base for adhesion to finishes, like paints.

Pickling is a metal surface treatment used to evacuate impurities, like stains, inorganic contaminants, rust or scale from ferrous metals, copper, valuable metals and aluminum composites. It is usually used to descale or clean steel in different steel making processes. It efficiently removes welding spots and oxide layer from stainless steel.

Chemtex Speciality Limited is an ISO 9001, ISO 14001 and OHSAS 18001 certified company that specializes in the manufacturing of pickling paste products. It has also established itself to be among world's renowned multipurpose chemical exporter having its facility in India. Chemtex's greatest business vitality and strength are its technical and manufacturing knowledge and a well developed technical service team. 

Pickling helps in removing a thin surface layer from the stainless by using an acid solution, which is usually a hydrofluoric and nitric acid mixture. 

Pickling of metals will evacuate embedded iron deposits, heat tin and weld scale. It has quality to expel free iron sullying from the stainless steel surfaces all alone, significantly utilized as a part of steel industry.

The Pickling and Passivation Chemicals are used for preventing corrosion to components made of stainless steel and as a result considerably influences in improving their life and productivity. Pickling helps in removing a thin surface layer from the stainless by using an acid solution, which is usually a hydrofluoric and nitric acid mixture.

In addition, pickling will remove embedded iron, heat tin and weld scale. Whereas passivation is involving nitric acid in the solution, which can take place both in successions and simultaneously. Nitric acid is a strong oxidizing agent used for chemical passivation. It has the required strength to remove free iron from the stainless steel surfaces on its own, majorly used in steel industry. The products which we cater under this category are Pickling Paste, Passivation Gel, Stainless Steel Welding Spot Removing Paste, Acid Neutralizing and Passivating Chemical and Water or Brine System Cleaning & Passivating Agent.

Chemtex's Stainless Steel Pickling Paste is an exceptional formulation for pickling of Stainless Steel surfaces. Application of the same efficiently removes welding spots and oxide layer from SS surfaces.
