Corrosion Inhibitors

Nothing is more counterproductive to superior surface finish than corrosion. Highly-effective Master STAGES corrosion inhibitors provide excellent protection on metals ranging from cast iron, steels, and other ferrous metals, aluminum and copper alloys, brass, and bronze with protection ranging from several days to a full 12 months and longer. Whether needing indoor corrosion protection during interim steps of the machining process, long-term outdoor protection, or for shipping parts overseas, there is a Master STAGES product to give you the assurance you need.

Master STAGES rust preventatives (RPs) can be applied by dip, flood coating, ambient-temperature or heated spraying, roller, or brush, are easily removed — and most are barium-free with low V.O.C. content. Get cost-effective protection you can rely on with Master STAGES RPs.

Master STAGES ™ CLEAN 2029 "One Step"

Parts Washing Fluid with Corrosion Inhibitor

Master STAGES™ CLEAN 2029 “One Step” is a highly concentrated cleaner/corrosion inhibitor designed for spray washers and immersion tanks. This product will remove heavy soils and provide two-to-four weeks of indoor corrosion inhibition on steel and cast iron parts.

  • Formulated without silicates or other high pH additives, CLEAN 2029 “One Step” is compatible with ultrafiltration systems and bioremediation
  • An excellent choice for cabinet-style spray washers and can be used for washing steel, stainless, cast iron, titanium, and many aluminium alloys
  • Hard water tolerant, it provides long bath life
  • Environmental approvals are simplified because CLEAN 2029 “One Step” contains no nitrites, barium, phenols, or butyl cellosolve
  • This formula has very low V.O.C. content
  • Low foaming for use in high-pressure spray washers with temperatures above 60°C

Master STAGES ™ CLEAN 2115AL

Low Foam Spray Washing Compound

Master STAGES™ CLEAN 2115AL is an aluminium compatible, high performance, low foam synthetic washing compound for use in very high-pressure spray washers, de-burring, and water jet cutting. Advanced surfactant technology provides excellent foam control and tramp oil rejection.

  • Compatible with a wide range of materials including aluminium, cast iron, steels, zinc, plastics, and composites
  • Resists foaming even when contaminated with large quantities of soils or coolant. This makes CLEAN 2115AL an excellent choice where rapid buildup of coolant carryover creates a foam problem
  • Many CLEAN 2115AL applications are in the range of 3,000 to 10,000 PSI (200-700 Bar)
  • Provides short term corrosion inhibition on cast iron and ferrous alloys

Master STAGES ™ NOCOR ™ S2

Water Soluble Corrosion Inhibitor

Master STAGES™ NOCOR™ S2 is a synthetic, water soluble, ferrous corrosion inhibitor for short-term storage or shipment. Effective at concentrations from 3%—10% in water, it provides a very thin, water soluble protective film.

  • The transparent film left by NOCOR S2 is easily removed and will not interfere with additional machining, gauging, or assembly steps
  • Barium-free and contains very low levels of volatile organic compounds as applied

Barium-free, Low Odor, Corrosion Inhibitor

Master STAGES™ RPO 6BF is a barium-free, nonstaining, water displacing, thin-film corrosion inhibitor or rust preventative which can be used on a variety of metals. RPO 6BF provides indoor corrosion inhibition, excellent protection for bearings and other precision parts, in-process parts in storage, as well as parts in transit.

  • Barium free
  • Light film for limited carryoff
  • Excellent corrosion inhibition, generally in excess of six months in dry storage
  • Nonstaining
  • Provides cleaning action
  • Water displacing to help prevent rust due to water trapped under the protective film
  • Oxidation resistant to resist tarnishing over long storage periods
  • Easily removed with detergent cleaners, such as Master STAGES™ CLEAN 2029 “One Step”
  • Humidity Cabinet Test: No rust at 650 hours (ASTM D1748)
