DACROLUB® is an organic finish obtained from water-dilutable products. This finish is applied to the coatings of the GEOMET® range, thus allowing the friction coefficient of threaded parts to be reduced and controlled. DACROLUB® is available in colourless, blue and green versions. The properties are identical, regardless of coloration.
- Dry lubrication film
- Coefficient of friction: 0.08 – 0.14 or 0.12 – 0.18 on GEOMET®-coated® screws measured according to ISO 16047
- DACROLUB® avoids stick-slip problems when screwing (VDA 235-203)
- Salt spray test according to ISO 9227: does not change the strength of the GEOMET® base coating layer
- The GEOMET® / DACROLUB® association is particularly suitable for screws, to which it gives optimal properties of resistance and mountability
- Due to their ease of application, coloured DACROLUB® can be used for workpiece identification
- Competitive cost
DACROLUB® is a technology composed of lubricants in a thermoplastic organic binder. It has been developed to meet the highest industrial requirements and environmental, health and safety regulations. It is water-based and nonylphenol-free.
