Dry film lubricants are coating materials in which solid lubricant particles are dispersed within a binder system. After application, they can cure at room temperature or under heat, forming a solid lubricating film with specific functional properties. These products combine the advantages of lubrication technology and surface engineering, making them an essential part of modern high-performance lubrication materials, and they are widely used across various industrial sectors.
To ensure that dry film lubricants deliver optimal performance, proper surface preparation and application procedures are crucial. The specific steps are as follows:
Before coating, it is essential to thoroughly remove oils, dust, and oxides from the substrate surface. Inadequate cleaning will directly affect the adhesion strength and service life of the coating.
The substrate should undergo chemical conversion (e.g., phosphating, passivation) or physical treatment (e.g., sandblasting, roughening) to significantly enhance the bonding between the film and substrate. This step is indispensable in the application process.
After surface pretreatment, any residues must be removed, and the substrate must be completely dry to prevent moisture or contaminants from compromising the coating quality.
Depending on the operating conditions and functional requirements of the components, an appropriate application method—brushing, spraying, or dipping—should be selected. The coating is then cured under the recommended conditions, forming a uniform and stable dry lubricating film.
Dry film lubricants are suitable for a wide range of materials, including metals, plastics, and rubber, and perform exceptionally well in situations where conventional lubricants are insufficient. They can be used in combination with conventional lubricants for synergistic effects or applied alone as a permanent or corrosion-resistant lubrication solution.
Their applications span office equipment, household appliances, automotive manufacturing, and general machinery, and extend to high-tech sectors such as aerospace. They are suitable for trial assembly, friction control, corrosion protection, and long-term lubrication requirements.
