It is important that the GLEITMO HMP-film does not change when it comes into contact with water, as the ambient air always contains a certain amount of moisture, and screws may also come into contact with splash water.

In the water resistance test it can be proven for the GLEITMO HMP-film that even after being stored in water for several hours, there is no deterioration in the lubricating performance.
