CRC SP-400 provides long-term corrosion protection for all metals, effectively resisting rain. It can be removed using any petroleum solvent. SP‐400 is a waxy, petroleum-based corrosion inhibitor designed to protect unfinished (non-painted) metal parts from corrosion during storage or general use.
Features
- Long-term corrosion protection.
- Displaces and seals out water and moisture.
- Safe for all metal surfaces; does not stain.
- Compatible with most rubbers, plastics, and coatings (test on sensitive materials before use).
- Removable or adjustable film thickness with petroleum solvents.
- Meets salt spray resistance criteria of MIL-C-16173E grade 4.
Applications
- Long-term outdoor corrosion protection.
- Corrosion protection during overseas transport.
- Seasonal corrosion protection.
- Protection for all ferrous materials.
- Brine or chloride resistance in refrigeration plants.
Directions
- Shake well before use.
- Stir or mix bulk products well before application.
- Apply only with adequate ventilation; do not use on energized equipment.
- Ensure the surface is clean and dry before application.
- Clean the aerosol valve by turning the can upside down and spraying until only propellant escapes.
- Film thickness can be adjusted by thinning with petroleum solvents, although corrosion resistance varies with thickness.
- For very humid conditions, apply CRC 3-36 first to ensure moisture displacement. Allow 2 to 4 hours for solvent evaporation before applying SP-400.
