Improving the corrosion resistance of metal-evaporated tape using dicarboxy acid as a lubricant

To improve the corrosion resistance and frictional durability of ultra-thin metal-evaporated (ME) tape, we have developed a new lubricant with two carboxyl groups that can improve corrosion resistance and frictional durability. The storage life of the ultra-thin ME tape with the new lubricant was evaluated using the Battelle Class II test and estimated to be more than 50 years.
