Solvent compositions and their use

摘要

Materials such as pipe dope, thread lubricants and like contaminants are removed from metal surfaces using a nonaqueous solvent composition comprising a surface active agent for breaking up and dispersing the materials, and D-limonene and a mixture of other terpenes including dipentene for dissolving the materials. The preferred surface active agents are alkyl naphthalene sulfonate diisopropyl amine salts, sodium di-2-ethylhexyl sulfosuccinate and blends of coco-diethanolamide and coco-sulfosuccinate. The composition may also contain glacial acetic acid.
