Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...

Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O.This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.
