Prevention of rust is the counteractive action or defer of rusting of iron and steel objects, or the lasting assurance against erosion. Depending upon mechanical and environmental conditions, the degradation may not be stopped completely, unless the process is periodically repeated. The term is especially utilized as a part of the vehicles business. Rust Preventive Oil serves as an effective product that prevents the infiltration of rust promoting nuclei into the metal components. This oil forms an effective barrier on the metal surface, between the metal surface and the atmosphere.

Rust Preventive Oil can be applied by dip, brush or spray. It is mostly used in places where corrosion inhibition is required before use.

Benefits of Rust Preventive Oil:
• Self curing and extends the life of metals
• Nontoxic and environment friendly
• Ready to use and easy to apply
• Provides excellent lubrication
• Acts effectively at room temperatures

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 manufactured by Chemtex Speciality Ltd. prevents corrosion of components made up of stainless steel and as a result it improves their life and productivity. Pickling helps to remove a thin surface layer from the stainless by using an acid solution, usually a hydrofluoric and nitric acid mixture.
Pickling removes embedded iron, heat tin and weld scale whereas Passivation involves nitric acid in the solution, which takes place both in successions and simultaneously. Nitric acid being astrong oxidizing agent is used for chemical passivation. It has 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• Water or Brine System Cleaning & Passiv

Polishing and buffing are the last but the most important processes for smoothing metal surface using abrasives. This procedure evacuates surface material which enhance the surface and set it up for buffing. This is for the most part a coarse operation including sandpaper and/or metal polishing compounds. Polishing includes expelling oxidation and enhancing quality of the metal by adding, removing, blurring  water soaked spots, sun spots or shadiness.

Usage/ApplicationDescaling
Sulfamic Acid serves as a descalant that can be used for the removal of process scales and water from industrial equipments. Sulfamic Acid serves as a superior cleaner and a potential descalant. Its aqueous solution shows the tendency to be less corrosive towards metals than other mineral acids. It appears to be odorless, non-hygroscopic stable acid which is mildly soluble in water. For a long time it is being used in the industrial sectors as cleaning agent and descaler due to its remarkable property of solubilizing of hard scale and other deposits. Furthermore, it can be used safely over equipments made of stainless steels as it avoids pitting or chloride induced stress corrosion cracking. It also serves in the elimination of hard water scale, protein deposits, copper corrosion, beer and milk stones and light rust. It cuts through excessive grout from tiling and solubilizing efflorescence from floors and walls. It finds applications in many desalination plants to clean heat exchanger, cooling water system, demisters, etc. It can be safely used on steel, iron, glass, wood equipments and with precaution can be also used on galvanized metal surfaces, copper, and aluminium.
Key Attributes and benefits:• Can be used in Dye and pigment manufacturing• Used as a Coagulator for urea formaldehyde resin.• Ingredient in fire extinguishing media.• Can be used as herbicide and fire retardant material.• Can be used in Pulp and paper industry as a chloride stabilizer• Synthesis of nitrous oxide by reaction with nitric acid

Oil Phase Corrosion inhibitors rely principally on the formation of barrier coatings preventing water from metal surfaces. Since the product is in ready to use form, it can be used directly from the container without any need of preparation.  
The most common problem encountered in crude oil industries is corrosion. It degrades all the metal components of pipelines, drilling bits, etc. With continual extraction of CO, HS, water, oil the equipment undergo corrosion resulting in loss of mechanical properties of the materials and eventually leading to metal loss. Corrosion inhibitors protects both ferrous and non-ferrous metals like stainless steel, copper, aluminium, brass, copper, zinc, tin, bronze, and lead.
For parts that need longer term protection (months to years) or those stored in severe environmental conditions (i.e. outside storage) oil-based inhibitors are preferred due to their heavy film and the water rejecting properties they possess. The protective coating they form varies (semi-hard, soft, oily, transparent, colored) with the specific product.
Attributes & Benefits:
• Good material compatibility• Longer protection• Selective coating on metals• Applied by brush, dip and spray methods

Surfactants are so-called surface-active substances, as they reduce the surface tension of liquids due to adsorption at the surface. Surfactants are categorized according to the nature of the hydrophilic group:• Anionic surfactants • Carboxylates or sulphonatesoften in the form of alkaline metal salts• Cationic surfactants like quaternary amines• Ampholytic surfactants, frequently carboxylate and quaternary amine group• Non-ionic surfactants like Alcohol • Ether or ethoxylate.
Surface Treatment of metals 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
Chemtex Speciality Ltd. manufactures a wide range of 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.
