Dry film coating! Fasteners for vacuum environments with "baking prevention function."
"Tungsten disulfide (WS2)" is a product that excels in lubrication and demonstrates a low friction coefficient, solving issues of "seizing" and "galling" in vacuum environments. It alleviates troubles arising from machinery and equipment, reducing downtime. It addresses difficult friction, wear, sticking, galling, and erosion caused by various extreme environmental conditions, particularly ultra-high vacuum. 【What is WS2 Dry Film Coating?】 - Maintains dimensional accuracy with a coating thickness of less than 1μm and durability - Reduces the burden on personnel involved in maintenance work and lowers costs - Decreases the accumulation of deposits on sliding surfaces - Cleans the environment - Enhances safety *For more details, please download the PDF or feel free to contact us.
