Iron, the main component of neodymium magnets, is easy to be oxidized, so neodymium magnets are not waterproof and corrosion-resistant. If you want to use neodymium magnets outdoors or in other places with high air humidity, it is best to choose neodymium magnets with special waterproof coating. Here we introduce neodymium magnets with different waterproof coatings. they are called waterproof (coated) neodymium magnets.
The waterproof layer of the waterproof magnet is by no means an ordinary electroplated coating, but a durable protective layer is added to the electroplated magnet, such as plastic, rubber, etc. The colors of strong waterproof magnets are more diversified. You can buy neodymium waterproof magnets with plastic and rubber coating in different sizes and colors. The waterproof neodymium magnets also have the advantages of wash-ability and scratch resistance.
Different applications will require other coatings. According to the classification of coatings, our neodymium waterproof products are available in the following types:
Plastic-coated waterproof neodymium magnets with complex coating layers are known as unbreakable magnets.
Rubber-coated waterproof neodymium magnets that have soft surface to increase the friction.
Teflon coated magnets of waterproof neodymium that have an environmentally friendly waterproof coating.
PVC-coated waterproof neodymium magnets that have soft and sewable coating,they are used as washable magnetic buttons.
Neodymium disc magnets with waterproof coating are used as button magnets,you can use them on whiteboard.
Neodymium rod magnets with waterproof coating can be well embedded in the round holes..
The China neodymium ring magnet has a hole in which you can drill screws, for example, as an additional fixture. Magnets can also be attached to non-magnetic surfaces.
Block magnets with waterproof coating are widely used as magnetic holding application.
The countersunk holes varies depending on the magnet dimension. Waterproof magnets with countersunk holes are used as outdoor mounting.
The NdFeB magnet is composed of iron which is easy to oxidize, so the NdFeB(neodymium)magnets are not waterproof.
To make neodymium magnet waterproof, it is necessary to coat the surface with materials other than electroplated coating, which can isolate moisture.
Rubber or plastic coated neodymium magnets and pvc sewing magnets have characteristic of waterproof.
The nickel plated neodymium magnet can only be used outdoors for a period of time, and it will still be oxidized after long use.
