Long-term indoor corrosion inhibitor. CRC SP 350 Corrosion Inhibitor is a heavy-duty indoor corrosion inhibitor providing extended protection for all metal parts and assemblies both in storage and during shipments. Its unique formulation, to resist run-off and flow, easily covers planed surfaces and sharp edges, making it particularly effective on precision machined surfaces.

Excellent long-term lubricant for metal parts subjected to heavy duty and constant wear
Thin, non-drying penetrating and protecting film
Protects equipment and parts in storage, shipment and in process
Promotes easy start-up
Suited for all metals and alloys, included copper and brass
Can be easily removed with solvent cleaners
Equipped with the 360° (upside-down) spray valve for added convenience
Pressurised with non-flammable CO2 propellant
Active product content of 97 %
Specifications : NSN 8030-25-100-4662
Final film for completed assemblies
Protective coating for assemblies in storage, shipment and process
Precision machined surfaces
Aircraft faying surfaces
Seasonal ‘moth balling’ of marine engine blocks, pistons and components
Protection of cutting tools, workbench tops, fixtures, gears and shafts.
Maintenance and storage of weapons
Start-up lubricant for stored machinery
Shake aerosol can well before use. Stir or mix bulk product to break its gel structure before dipping applications.
Spray a light, even coat to surfaces to be protected. Use extension tube for hard-to-reach areas and for spot lubrication. For electrostatic spraying, addition of a polar solvent may be necessary.
To be removed by solvent cleaners (CRC Industrial Degreaser, CRC Fast Dry Degreaser, ...), alkaline cleaners or steam before surface treatment.
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.

Typical corrosion protection results will depend mainly on surface conditions and indoor environment. It may be less than 3 month or more than 2 years.The first application therefore should be checked periodically for signs of corrosion. Once the time of protection under any specific condition is determined, CRC SP 350 may be re-applied at intervals to maintain protection.
