Corrosion inhibitor

Cosmoline PTC (for pipe, tubing and concrete), is a new water-based coating that inhibits rust and corrosion on pipes and tubing. When applied during the manufacturing process, it improves the ability of pipes and tubing to resist general or uniform corrosion and localized pitting corrosion. General corrosion is caused by water and gases in the air, while pitting corrosion can occur from acids produced by bacterial action on organic materials on the surface of the pipe. Cosmoline PTC is formulated with organic materials that show resistance to this type of bacterial action, the company reports. Houghton International www.houghtonintl.com
