Rust Preventives

Products designed for two basic functions: to prevent the substrate from being attacked by detergent during the cleaning process, and to prevent oxidation of the metal after cleaning. The DuBois brand range of corrosion inhibitors are for parts that will be stored indoors.

RUST PREVENT SYN 3-X is water soluble and contains no oil. When diluted with water it forms a clear solution. RUST PREVENT SYN 3-X contains no chlorine, sulfur, silicone, phenols, or nitrites.

Benefits:

  • Concentrated formula makes even very dilute 1.5% solutions effective.

  • Non-Nitrite, water soluble synthetic formula.

  • Wets out on the metal surface providing complete coverage.

  • Will inhibit rust for approximately 30 days of indoor storage.

  • Excellent for use as an interim flash rust prevent in paint pretreatment systems.

  • Use when machining or cleaning cast iron to prevent rust.

  • Dilution is clear and easy to see through.


Medium Term - Soluble Oil

Protection against corrosion for 60 to 180 days.

GX PROOF 6151

Synthetic based rust preventative that provides long-term protection with a dry imperceptible film. It was developed to be used on all metals and is environmentally safe.

Benefits:

  • Superior corrosion, humidity protection.

  • Safe on all metals.

  • Provides clear, dry film, easy to apply.

  • Displaces water from metal surfaces.

 

LAB OIL 100

Water soluble emulsion type rust preventative that can be applied over phosphate, black oxide or bare steel. LAB OIL 100 combines the properties of high corrosion resistance, "dry to the touch" (over phosphate), excellent emulsification characteristics and low toxicity.

Benefits:

  • Contains no barium compounds.

  • Emulsions of LAB OIL 100 applied over zinc phosphated steel panels have survived in excess of 240 hours of salt spray exposure (ASTM B-117).

  • Formulated to also offer excellent emulsion stability to alkaline or acid contamination as encountered in black oxide or phosphating processing cycles.

 

Perkote 80-325

Oil-type rust preventive ideal for protecting metal surfaces from corrosion. Perkote 80-325 is an economical, versatile oil that generally has been used in the cold drawn steel industry as a straightener slushing oil or as a final rust preventive for steel bars.

Benefits:

  • Polar additives provide exceptional water displacing characteristics.

  • Humidity test panels exceed 30 days protection which indicates indoor storage protection in excess of 1 year.

  • Black stain inhibitor prevents black metal to metal contact stain.

  • Easily applied by dipping, spraying or brushing.

  • Readily removed with conventional cleaning methods.

  • Contains no materials that are considered hazardous or flammable.

 

RUST PREVENT 100

Water-soluble oil rust inhibitor typically gives 3 to 6 months indoor rust protection. It is extremely easy to clean off using mild alkaline cleaner. RUST PREVENT 100 is easily applied by dipping, brushing, or spraying. It is especially good for dip application on parts whose configuration is such that flooding provides the best or only method of getting RUST PREVENT 100 to the place of contact.
