                    Brand Name : CRC
                    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

                    • 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.
