TECHNICAL DATA SHEET 1/2 CRC RUST REMOVER Ref. : 10460 1. GENERAL DESCRIPTION Scale and rust remover concentrate.CRC Rust Remover is a phosphoric acid based concentrate used to remove rust and toclean metal surfaces. It cleans tarnish, oxidation, stains, fingerprints and scale from iron,steel, copper, brass and aluminium. 2. FEATURES • Excellent wetting capacity on both ferrous and non-ferrous metals. • Contains an inhibitor to reduce the attack of the metal surface and to prevent the formation of hydrogen. • Economical concentrate.• Can be diluted with water to any concentration needed (see Directions for detailed information). • Specifications : meets the performance requirements of Mil-C-10578 (type III). 3. APPLICATIONS • Rust and scale removal from : ferrous metals non-ferrous metals • Oxidation and stains removal from : aluminium copper brass, ... • Metals preparation prior to painting • Cleaning of : in-process parts and assemblies sheet metal • Restoration of rusted parts. • Removal of metal and rust stains from porous materials. 4. DIRECTIONS • Heavy rust and scale (ferrous metals) : dilute concentrate with 3 parts water. Metal should be immersed 20 minutes to 1 hour. Remove and rinse metal with water and treat immediately with CRC 3-36 for water displacement and corrosion protection. • Heavy corrosion (non-ferrous) : dilute concentrate with 7 to 10 parts water. Metal should be immersed 20 minutes to 1 hour. Periodically check non-ferrous metals. Remove and rinse with water. Treat immediately with CRC 3-36 for water displacement and corrosion protection.
As a metal cleaner (ferrous and non-ferrous) : dilute concentrate with 15 to 20 parts water. Metal may be immersed, brushed or wiped until the desired brightness is obtained. Rinse with water and treat immediately with CRC 3-36 for water displacement and corrosion protection. • Heating (up to 65°C max.), agitation or wiping will speed up cleaning action. • Quicker results are obtained by prior removal of oil and grease, using CRC Industrial Degreaser or CRC Fast Dry Degreaser. • CRC Rust Remover is mildly acidic; therefore, reasonable care should be taken. Rubber gloves and protective goggles are recommended. • Equipment used must be made of acid resisting material such as stainless steel, wood, rubber, plastic, glass or ceramic. • A safety data sheet according EU directive 93/112 is available for all CRC products. 5.
