Protect your products! Silver tarnish inhibitor New Dine Silver S1
Silver is generally prone to sulfide formation, which has the drawback of reacting with hydrogen sulfide to produce blackening. This discoloration can progress beyond superficial changes to internal corrosion, leading to issues not only in aesthetic appeal and product value but also negatively affecting surface functions such as solderability and contact electrical resistance. This is an important product that can improve those effects. This product is a general-purpose item with good water repellency. [Usage Scenarios] - Prevention of silver discoloration [Effects of Introduction] - Can be used on silver and silver-plated surfaces without color change.
