Tapping Paste is a type of metalworking oil. That is a lubricant used for cutting.
Using MonoTrap RGPS TD and HandyTD TD265, we conducted a simple screen-analysis of the volatile constituents arising from Tapping Pastes and compared the volatile constituents of new and older Tapping Pastes.
Refresh and fragrance ingredients such as pinene and limonene were detected in the new tapping paste, while these ingredients were not detected in the old tapping paste, and components such as fatty acids, which may be derived from the oxidation of the oils, were detected with high sensitivity.
