Long-term outdoor and indoor corrosion inhibitor. CRC SP 400 ANTI RUST COATING is a long-term, outdoor and indoor corrosion inhibitor for machined surfaces and assemblies subjected to long periods of storage or adverse shipping conditions.The amber, dry, waxy film never becomes brittle and is highly resistant to humidity and severe corrosive atmospheres.
Long-term protection (up to 1 year outdoors) for all metals during shipment or extended storage
Waxy film seals out moisture effectively
Highly resistant to humidity and salt spray
Can be removed or diluted, for film thickness variation, with petroleum solvents
Aerosols use hydrocarbon propellant for controlled application and film thickness
meets Mil-C-16173, grade 4
Protection of finished components, in-process parts, in-transit goods, raw materials, structural steel.
Effective corrosion shield for overseas shipments, ‘winterising’ of farm machinery, outdoor storage.
Protection of equipment, tools, dies, molds, jigs, pipes, shafts, housings, wire ropes, valves, gears.
To be used for brine and chloride resistance in refrigeration plants.
In paper and pulp plants.
As a cable end sealer and pipe joint protector in utilities .
Protection of air conditioning and electrical equipment in hospitals and educational institutions.
In airport and aircraft maintenance and construction.
Shake aerosol can well before use. Stir or mix bulk product to break its paraffin structure before dipping or brushing applications.
Mask area not to be treated. If necessary, remove by solvent cleaners (CRC Fast Dry Degreaser, CRC Industrial Degreaser,...).
Film thickness may be adjusted by thinning with petroleum solvents, but corrosion resistance varies with film thickness (see typical properties).
When finished spraying, clean aerosol valve by turning can upside down and pressing actuator until only propellant escapes.
Do not use on energised equipment. Use in well ventilated areas.
A Safety data sheet (MSDS) according EU directive 93/112 is available for all CRC products.
