Cooling automotive industry

Sodium benzoate is also finding increasing appHcation as a corrosion inhibitor. It is incorporated into paper wrapping materials for the prevention of mst or corrosion in the production of such diverse items as razor blades, engine parts, bearings, etc. It is also used in the automotive industry as a corrosion inhibitor in engine cooling systems (at 1.5%), mainly in Europe and Japan. Unlike in its appHcation as a preservative where free benzoic acid is required to provide antimicrobial action, it appears to be the benzoate ion that provides the corrosion protection. 

Hazardous Decomp. Prods. Decomp, may produce toxic fumes of CO, CO2, NO, fire may produce irritating or poisonous gases Storage Store in a cool, dry place keep tightly closed Uses Colorant, pigment for plastics (vinyls, polyolefins), paints/coatings, automotive, industrial, and architectural finishes, printing inks, enamels, lacquers, textile inks, artists colors colorant in food-contact polymers, hair dyes... 

The fluid is mostly heated and cooled instantly during the process by a heating/cooling unit which also supplies the fluid flow. However, some approaches are trying to separate the heating from the cooling and are therefore isothermal for each station. The isothermal approach is mostly used in high volume production such as the automotive industry, often in combination with the use of thermoplastic CRFP and/or other thermal control units.

Fluid Specifications. The performance characteristics of all antifreeze solutions are governed by fluid specifications, that have been developed over the years by industry standards committees, such as the American Society for Testing and Materials (ASTM) and the Society of Automotive Engineers (SAE). Additionally, most engine and/or cooling system manufacturers have thek own compositional specifications to which the fluids must conform.
