What is the difference between hard film rust preventive oil and soft film rust preventive oil?

The anti-rust oil is composed of an oil-soluble corrosion inhibitor, a base oil and an auxiliary antioxidant, and is specifically used as an anti-rust treatment for steel parts. Anti-rust oil is divided into soft film anti-rust oil and hard film anti-rust oil.

The anti-rust treatment of soft film anti-rust oil has a weaker professional ability, but it is easy to remove with organic solvents such as gasoline and kerosene, which is convenient. The hard film anti-rust oil has strong anti-rust treatment ability and long anti-rust treatment time, because the anti-rust film produced has high compressive strength, and the oil film is stable and not easy to eliminate.
