VpCI ®(Vapour Phase Corrosion Inhibitor) as an additive added to cleaning fluids that protects metals against flash corrosion.

ProductProduct DescriptionBenefitsApplication
M-95M-95 is a very low foaming, water soluble corrosion inhibitor concentrate.Versatile water soluble additive for various multi-metal systems requiring vapor phase and contact protection. Causes little to no foam. It provides corrosion protection for steel, copper, brass, magnesium, aluminum, bronze, galvanised steel, and other ferrous and non-ferrous metals and their alloys. M-95 prevents corrosion in both phases: contact and vapor.Protection of distillation towers. Petroleum processing. Synthetic coolants and cutting fluids. Industrial cooling towers. Water based lubricants. Aerosol formulations. Paint additives. Treating baths for copper and copper alloys. Alkaline metal cleaners. Radiator fluid additive. Anti-freeze ethylene glycol/water based formulations.
M-235M-235 is a proven corrosion inhibitor for copper, copper-based alloys and other yellow metals.Prevents corrosion of yellow metals. Functions by reacting with surface copper oxides to form a strong, insoluble polymeric complex. This complex creates a thin layer or film on metal surfaces that provides both a mechanical and electrochemical barrier against corrosive attack. This protective layer has a high degree of thermal and oxidative stability and cannot be easily removed. Direct treatment on rolled copper or brass sheets and coils. Circulating cooling systems such as cooling towers. and air conditioning systems. Functional fluids such as hydraulic fluids, specialty lubricants, automotive coolants and metalworking fluids. Wrapping paper and box board for wrapping, interleaving, shipping and storing copper and brass items. Corrosion protective coatings such as lacquers and waxes. Cleaners such as soaps, detergents and strong alkali or acid cleaners. Fabricated products made from copper and brass. Artifacts, sculptures and decoration items.
M-238M-238 is a solvent-based blend of contact and vapor phase inhibitors.Designed as an additive to aromatic, paraffinic, naphthenic, fluorocarbon and hydrocarbon-based products. Effective vapor and contact corrosion inhibitor for a variety of oil-and solvent-based systems.Solvents. Synthetic formulations. Hydrocarbon formulations.
M-370M-370 is a multimetal, corrosion preventive additive.For alkaline cleaners/degreasers. Prevents flash corrosion on metal surfaces and forms a hydrophobic film that is virtually undetectable when dry. Also available in A (aluminum), NS (non-surfactant), HS (high surfactant), and C (additional protection for cast parts and rough surfaces) versions.For water-based metalworking fluids, lubricants, cleaners and coatings during product manufacturing. 
M-415M-415 is made from FDA and USDA approved corrosion inhibitor additives.Strong vapor phase corrosion inhibitor additive for cleaners. Contains FDA and USDA approved ingredients. It is silicone and surfactant-free and can be introduced to formulations at virtually any step of production. For oils and solvent based paints, sealers, adhesives, fluids, and more.
M-435M-435 is a multi metal organic corrosion inhibitor additive.Versatile, no-VOC flash rust corrosion inhibitor for water-based fluids. Can also be used in solvent-systems. It is silicone and surfactant-free and can be introduced to formulations at virtually any step of production. For water and solvent-based paints, sealers, adhesives, fluids and more.
