CRC SP 350 Corrosion Inhibitor

Product Description

1. GENERAL DESCRIPTION

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.

2. FEATURES

• Heavy-duty corrosion protection up to 2 years indoors

• Excellent long-term lubricant for metal parts subjected to heavy duty and constant wear

• Thin, non-drying penetrating and protecting film

• Displaces moisture

• 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

3. APPLICATIONS

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

4. DIRECTIONS

• 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.

Effective Corrosion Protection

CRC SP 350 acts as a powerful barrier against rust and corrosion, ensuring metal surfaces remain intact during storage and transit. Its thin film minimizes material waste while delivering dependable protection, making it ideal for industries dealing with sensitive metal components.


Simple Application and Removal

Packaged in a convenient aerosol spray can, SP 350 offers effortless and uniform application. When re-coating or further cleaning is required, the protective film can be quickly removed using a CRC cleaner, streamlining maintenance procedures and reducing downtime.


Wide Coverage and Longevity

A single 16 oz (454 g) aerosol can covers up to 1,600 sq. ft., making it highly economical for large-scale operations. When stored unopened in a cool, dry place, CRC SP 350 maintains its efficacy for up to two years, meeting professional standards for reliability.
