Silver Tarnish Prevention - New Dain Silver
Silver tarnish inhibitor
Silver, silver alloys, or silver-plated products are widely used in tableware and jewelry due to their beautiful silver color. Furthermore, they possess excellent electrical properties such as solderability and contact electrical resistance, making them useful as contact materials in electronic components. However, silver generally tarnishes easily, particularly through sulfide formation, changing to yellow, purple, and in severe cases, black. The tarnishing of silver not only detracts from its aesthetic appeal and reduces its commercial value but also adversely affects solderability and contact electrical resistance. New Dain Silver prevents silver tarnishing for an extended period with a very simple room temperature, short-duration immersion treatment. The protective film formed by the New Dain Silver treatment is an extremely thin organic chelate film. The treatment does not alter the appearance of silver or degrade its solderability or contact electrical resistance.
