Dry lubricant – SV-BNP has excellent lubricating properties due to its low Coefficient of Friction.Non-abrasive: The smooth molecular structure of SV-BNP does not let the interiors of the vacuum chamber get scratched or grazed while removing the stuck aluminum.Chemically Inert: Since SV-BNP is chemically inert, it releases neither any gases nor harms the vacuum chamber walls even at very high temperatures.
