12oz Aerosol Can - Non-Hazmat, Non-Flammable & Non-ToxicCorrosion Block is a clean fluid that actively protects metal using advanced polar bonding chemistry. Synthetic additives in Corrosion Block completely penetrate corrosion cellsa |replacing the salt water which is then allowed to evaporate. Corrosion Block's hydrophobic film remains to further protect the metal acting like an "OFF SWITCH" for corrosion. Unlike waxy products Corrosion Block then leaves a clean clear moisture proof/hydrophobic film to prevent new corrosion formation. deeply penetrating into joints, connectors and around fasteners. Features:Formulated to KILL CORROSION ON CONTACT from completely submerged, to equipment affected by high moisture content in the airCorrosion Block is a clean fluid that actively protects metal and electronics using advanced polar bonding chemistrySynthetic additives in Corrosion Block completely penetrate corrosion cells...replacing the salt water which is allowed to evaporateA hydrophobic film remains to further protect the metal acting like an OFF SWITCH for corrosionCorrosion Block is safe; it is non-toxic and non-flammable, also the propellant used in our aerosol products is non-flammableUsed worldwide to protect electrical and mechanical equipment in Safety First situations such as Mining, Power Generating Stations, Fuel Depots, Gas and Petroleum refineries and moreProtects:SwitchesPressure GaugesMotor Operated ValvesTerminal StripsCircuit BreakersLocks ElectronicsBattery TerminalsRunning LightsFuel TanksFuse PanelsConnectorsAlternator LeadsReefer Unit Wheels & HubsEngines GPS Systems
