Everlube-coated magnets have advantages such as corrosion resistance and wear resistance. This allows high-performance magnets, such as neodymium magnets, to be used in harsh external environments. This article will provide you with some information about Everlube-coated magnets.
Meaning of Everlube
Everlube is a thermoset solid lubricant containing polytetrafluoroethylene (PTFE), molybdenum disulfide, and a high-molecular phenolic adhesive. Everlube has excellent wear life, abrasion resistance, good chemical stability, and performs particularly well in high-load applications. Everlube is widely used in the coating and lubrication of high-end products.
Why Use Everlube Coating For Magnets
Magnet coating is an important application direction for Everlube, such as Everlube 6155 and Everlube 10047. Everlube coating has many advantages over other types of magnet coatings. It can prevent wear and corrosion, and also improve assembly with other parts. Everlube coating facilitates the use of magnets in complex environments, therefore many high-end magnets use Everlube coating.
Physical Properties of Everlube Used For Magnet Coating
| Volatile Organic Compounds (VOC) | 575 g/L |
| Hardness | >4H |
| Temperature Range | -100° to 375°F (-73°C to 191°C) |
Advantages of Everlube-coated Magnets
| Everlube coating is a PTFE-based organic thermoset dry film lubricant. PTFE gives Everlube-coated magnets good corrosion resistance and chemical resistance.
| Everlube coating is also a dry film lubricant coating mixed with molybdenum disulfide and organic binder, which gives Everlube-coated magnets very good wear resistance, improves the life of magnets, and also provides good lubrication performance in high-load environments.
| Everlube coating can also be provided in different colors according to customer requirements.
Technical Information on Everlube-coated Magnets
Is Everlube coating resistant to strong acid corrosion?
Everlube coating has good chemical corrosion resistance and a certain tolerance to many chemicals. However, it cannot withstand strong acid corrosion.
Is the processing technology for Everlube-coated magnets spray coating, electroplating, or other?
Everlube coating mainly uses spray coating technology. This process allows the coating to adhere evenly to the substrate surface, ensuring good adhesion and performance.
Is nickel plating required as a base layer when using Everlube coating for magnets?
Nickel plating can be used as a base layer before applying the Everlube coating to improve its adhesion and wear resistance. This process can enhance the surface’s smoothness and adhesion, thereby improving the coating’s overall performance.
How long can Everlube-coated magnets generally last in a salt spray test?
The specific duration depends on the magnets’ structure and shape. Generally, they can achieve over 120 hours in salt spray tests. However, Everlube-coated magnets with holes generally have more difficulty passing salt spray tests.
