The CAIG Laboratories DN5S-2N 1.4oz DeoxIT DN5 Contact/Connector Treatment is a versatile product that can improve conductivity, reduce intermittent connections, and protect against arcing and RFI on all metal connectors and contacts. This fast-acting deoxidizing solution also rejuvenates and lubricates, reducing wear and abrasion on metal surfaces. With a temperature range of -34 C to +200 C and a non-flammable formula, it can be safely used on a variety of surfaces, including plastics. For severe oxidation and corrosion, it can be used on non-critical metal surfaces. However, compatibility should always be tested, especially on critical or sensitive parts and older equipment with aging ABS plastics.
