Phosphate Coatings

Phosphate coating is the treatment of Iron, steel, galvanized steel, or aluminum with a dilute solution of phosphoric acid and other chemicals in which the surface of the metal, relating chemically with the phosphoric acid media, is converted to an integral, mildly protective larger of insoluble crystalline phosphate.

Degreasers

These compounds are used primarily for removing mill oil, soil, forming lubricants, etc. from metal surfaces. Most modern cleaners in this group are made up of synthetic surfactants or detergents, water conditioning chemicals, and caustic or other alkaline materials. The synthetic surfactant emulsifies petroleum. Oils, so they can be removed. The alkaline portion reacts with animal or vegetable oils and converts to soap which is solvable. They also have a regenerating effect on some of the surfactants. The water conditioning material makes the rinsing easier. Heat is used to soften the various greases and oils, so they can be emulsified more rapidly. Synthetic surfactants have a definite temperature range where they work well, so follow the instructions on the data sheet.

Acidic Cleaners and Descalers                 

In metal working, It is sometimes necessary to remove rust, scale, corrosion, oxidation or other material that is not soluble in alkalis. For this, we have a full line of liquid. Each has its own place in the line. All acid react with mist common metals and dissolve them to a certain extent. Some of our acid compounds are inhibited. They work rapidly on rust, scale, silica and corrosion products, but have very minimal effect on the base metal.
