We offers Metal Pretreatment Chemicals like degreasing chemicals, derusting chemicals, activation chemicals, accelator chemcials, passivation chemicals, lubrication chemicals, etc
Degreasing chemcials have a significant bearing on the nature of the phosphate coating & the type of cleaner used determines the crystal size. Alkaline Degreasing chemicals are cleaner for removel of oil & grease prior to phosphating. It can be applied by dip or brush & suitable for degreasing both ferrous & non ferrous metals.
CLEANER ST- 30
Synthetic detergent base, removes all kinds of oils.
Derusting chemical removes rust & destroys corrosive agents, and retards further rusting. It is far superior to ordinary mineral acids. It is available in different types & grades for various cleaning jobs.
Ecellent for removel of thin heat scale & rust from steel tubes.
The Activation rinse is desirable for Zinc phosphating as it increase the corrosion resistance of the zinc phosphated & painted component. The coating achieved by treating the components, through a properly designed & maintained bath, is more compact and refined.
A phosphate-based lubricant soap system is superior to all other lubricants for severe extrusions because of the ability of the coating to flow with the metal as it is deformed, reducing metal to metal contact. This characteristic is the result of strong metal-to-phosphate bonds, which are formed during coating and the excellent extreme-pressure properties of the soap used as a supplementary treatment. Phosphate-soap coatings extend tool life, permit faster drawing speeds, allow for maintenance of closer dimensional tolerances, and produce a smooth, glossy surface on the finished parts. Zinc phosphate coatings are typically used in this application.
