Liquid Pump Spray - 4oz - Non-Hazmat Non-Flammable & Non-Toxic Corrosion 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 air Corrosion Block is a clean fluid that actively protects metal and electronics using advanced polar bonding chemistry Synthetic additives in Corrosion Block completely penetrate corrosion cells..replacing the salt water which is allowed to evaporate A hydrophobic film remains to further protect the metal acting like an OFF SWITCH for corrosion Corrosion Block is safe; it is non-toxic and non-flammable also the propellant used in our aerosol products is non-flammable Used worldwide to protect electrical and mechanical equipment in Safety First situations such as Mining Power Generating Stations Fuel Depots Gas and Petroleum refineries and more Protects: Switches Pressure Gauges Motor Operated Valves Terminal Strips Circuit Breakers Locks Electronics Battery Terminals Running Lights Fuel Tanks Fuse Panels Connectors Alternator Leads Reefer Unit Wheels & Hubs Engines GPS Systems.
