Borax Decahydrate is the refined form of natural sodium borate. Composed of boric
oxide (B2O3), sodium oxide, and water, it is a mild, alkaline salt, white and
crystalline, with excellent buffering and fluxing properties. Available in powder or
granular form, Borax Decahydrate is an important multifunctional source of B2O3,
particularly for processes in which the simultaneous presence of sodium is

Antifreezes (engine coolant)
Glycol-based antifreezes can oxidize to produce corrosive organic acids in automotive coolant systems. The buffering action of borates keeps the pH above 7 – preventing acid formation and inhibiting corrosion.
Borate polyols and polyamines in lubricants form an extremely resilient film on metal load-bearing surfaces. This film improves load capacity and protects from wear and tear. Potassium borates are used in high pressure lubricants due to their stable dispersion of microspheres.
Brake fluids are moisture sensitive. Absorbtion of water by the system reduces the boiling point of the fluid and can cause vapor-lock. Borates in brake fluids act to prevent vapor-lock.
Borates act as bacteriostatic agents in metal cutting emulsions. They are also corrosion inhibitors.Boric acid esters have led to high quality water-miscible cutting fluids with longer emulsion charge life.
