DOT 3 brake fluid is polyethylene glycol-based fluid that has been designed to withstand very cold temperatures without thickening and to endure high temperatures without boiling. The typical boiling temperature of DOT 3 brake fluid is around 250° C. This product usually has a yellow to amber appearance and a mild glycol odour. This product is slightly soluble in water however this does degrades the quality of the fluid if water mixes with the product. All DOT brake fluids must meet an industrial standard to be allowed for sale in the market place.
DOT-3 brake fluid is a mixture of glycerin and alcohol, otherwise known as glycol, with extra additives to give it the robust characteristics that are required.
Storage and Distribution
A chemical wholesaler would have a bulk petrochemical storage facility to maintain the product. Storage is normally in a cool, dry and well ventilated facility. DOT 3 brake fluids should be kept out of direct sunlight and exposure to moisture. Solvents such as DOT 3 brake fluid should be stored in drummed containers such as isotanks made of stainless steel, aluminium or carbon steel.
A bulk solvent exporter would normally distribute this solvent in bulk vessels or tank trucks. For transportation purposes, DOT 3 brake fluid is classed as only moderately flammable with a flammability rating of 1. A full bulk chemical distributor would export the solvent throughout regions such as the UK, Europe, Africa and America.
Brake fluid is used in braking systems of automobiles (commercial and industrial). Due to its viscosity, the fluid is able to transfer a manipulated force through hydraulic lines to the braking mechanism at the wheels.
