Abstract
This article reports on an investigation of the protective properties of resinous substances that are waste materials in the production of deresined wax. The protective properties of the resins extracted by BR-2 naphtha at 20/sup 0/C, 0/sup 0/C, and 5/sup 0/C, and also the ethanol-soluble and ethanol-insoluble components of these resins are examined. The results indicate that the peat wax resins do not show any corrosivity with respect to copper. At elevated temperatures, the resins are as good as the commercial additive Akor-1 in protective efficiency, and their alcohol-soluble components are better than the Akor-1. It is concluded that the good compatibility of the resins with mineral oils and their high level of protection make them suitable for use in liquid preservative formulations for the temporary corrosion protection of metal items.
