          CRC SP 350 Corrosion Inhibitor
          CRC SP 350 Corrosion Inhibitor
          Product Code : CRC SP 350
          Brand Name : CRC
          Product 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.
