The possibility of obtaining a conservation composition with elevated performance properties for protecting metal articles from corrosion in storage between operations in conditions of the humid tropical climate of Vietnam was investigated. It was shown that protective coatings containing atmospheric resid, vegetable oils (palm, soy, sesame, rubber) and Neftekhimeko-2 corrosion inhibitor have higher protective and water-displacing properties and biostability than the existing ZVVS-3 product.
