    Industrial applications of tungsten disulfide spray

    Application / processHow MK-WS2-SP is usedSelection note
    Automotive components Forms a thin dry lubrication layer on appropriate engine parts, pistons and piston cylinders. Check the substrate, operating temperature, component fit, and clearance.
    Bearings and precision gears Provides low-friction dry-film lubrication for suitable bearings, machinery parts and gears. Check load, speed, contact conditions and coating compatibility.
    Sliding and rotating parts Support for coating cams, rollers, spindles, shafts, seals, valves and actuators. Test adhesion and performance on the part it will go on.
    Plastic molds and extrusion dies Provides a low-friction coating for release applications indicated in the booklet. Check the appropriate surface finish and release action.
    Aerospace, defence and marine parts Forms a dry WS2 coating on compatible high-value parts. Complete all essential engineering, safety and compliance evaluation.
    Tools, punches and dies Ideal for low friction coating applications on cutting instruments, blades, slitters, knives, punches and dies. Validate tool geometry, coating life and processing conditions.

    Choosing tungsten disulfide aerosol spray

    Apply ready-to-use tungsten disulfide coating in aerosol format on components, tools, molds, dies or hard-to-reach places where powder-based or custom coating solutions are not practical. The appropriateness of the product depends on the substrate, load, speed, operating temperature, clearances, and the required coating performance.
