DeoxIT® GOLD (formerly ProGold), is a unique conditioning solution that improves conductivity and provides long-lasting protection on gold, base metals and other precious metal contacts and connections (gold, silver, rhodium, copper, bronze, nickel, etc.). Use on plated connectors, contacts and metal surfaces for maximum performance and protection. Recommended for critical applications where only slight cleaning action is necessary. If the surface looks clean, applying DeoxIT contact cleaner first is usually not necessary. DeoxIT® GOLD is designed to dissolve small amounts of oxidation. Apply DeoxIT® GOLD after DeoxIT® contact cleaner on plated metal surfaces, except where noted with DeoxIT® SHIELD below. The more critical the connection or part, especially low current applications, DeoxIT® GOLD should be the final step. For reference, DeoxIT® GOLD has approximately 0.5% cleaning action.

Physical and chemical changes in the surface condition of electrical or electronic connectors are primary causes of degraded performance of components and equipment. When contact surfaces are exposed to dust, smoke, gases, soot, and other solids suspended in the atmosphere, nonmetallic films form, inhibiting conductivity. Added resistance and friction between metal surfaces can also cause abrasion, noise, freeze-up, and in some cases, increased power consumption.

A common problem with plated surfaces, especially gold, is the "whiskering" (dendrite corrosion) of base metals on the surface due to gold's soft and porous nature. Once exposed, base metals oxidize causing a "blistering" of the surfaces, adding unwanted resistance that impedes electrical performance. The contact surfaces are actually separated by this blister, thereby reducing the effective contact area. Since gold plated surfaces are thinly coated, they are susceptible to scratching and abrasion, further exposing the base metals.

Conduction through a ProGold coated surface takes place in three ways. First, ProGold can be displaced by electrical arcing, shock wave or simple mechanical pressure and will redistribute itself along the surface when the disturbance is removed. Second, a thin insulating film of ProGold can be dispersed by an electrical field. Finally, conduction takes place through a very thin film of ProGold by means of a quantum- mechanical phenomenon called "tunneling." To avoid detoring into a discussion in physics, simply stated, electrons travel from one side of a thin film of ProGold to the other without passing through. (This is the same effect that gave the tunnel diode its name). ProGold fills the gaps in the contact surfaces, increasing the surface area and current flow (conductivity). ProGold penetrates the plated surface and molecularly bonds to the base metals to seal and protect it. Unlike other products, ProGold provides long lasting protection (1-10+ years) and will not gum-up, evaporate, varnish, char or breakdown.

ProGold coats the entire contact surface, providing superior protection from abrasion (insertion resistance), dendrite corrosion, arcing, RFI, wear, and atmospheric contamination. ProGold will significantly increase the performance and reliability of all electrical components and equipment.

Non-abrasive, non-corrosive, non-flammable, non-toxic and now even safer for the enviroment.
