Metallic anti-static additives

It is believed that to avoid any risk of explosion, the electrical conductivity of jet fuel should fall between 50 and 450 pS/m. This level is attained using anti-static additives which are metallic salts (chromium, calcium) added at very low levels on the order of 1 ppm. 

Metal Box has developed a copolymer polypropylene container. Poly-can, which has an anti-static additive and is suitable for water-based paints and coating products. Another development is the first bag-in-box paints from Ashwell Paints. A smooth flow is obtained in this system by the use of an open bung and screw top rather than a tap. 

Some additives used as anti-wear agents can also have anti-corrosion properties such as TCP, sebacic acid and azelaic acid. However, corrosion inhibition is a fine balance of competition with the anti-wear/load-carrying capability of the lubricant. Like the anti-wear additive, the corrosion inhibitor is designed to react with the metal surface. Some corrosion inhibitors specifically aimed at preventing static water corrosion of ferrous metals compete with the anti-wear additive for the metal surface to the extent that the resulting lubricant has poorer anti-wear properties than non-corrosion-inhibited lubricants.
