Neodymium magnets are useful for a wide range of application, however the coating will rust if exposed to rain or moisture for prolong period of time (a week or two).
Titan Magnetics plastic sealed disc neodymium magnet is suitable for use in wet areas as the neodymium magnet is fully encased in plastic. It is much more durable in wet environment compared to our standard triple coating of nickel, copper and nickel, and it can even be fully submerged in water.
4pcs of the same colour in a pack.
Q. Does it last forever?
A. No, although it is definitely more durable due to the added plastic coating, depending on the environment or liquid, plastic coating attached outdoor will get brittle that will results in small cracks that will compromise the coating. This is especially so when subjected to daily sunlight and changes in temperature, the colour will also fade due to natural UV exposure.
Q. Is this magnet as strong as standard neodymium magnets?
A. The strength of plastic coated magnet vs regular neodymium magnets of the same size and grade will be weaker due to the gap caused by the thickness of plastic coating.
Q. What is the maximum operating temperature of plastic coated magnets?
The maximum temperature for the outer plastic coating is 70°c while neodymium max temperature is 80°c.
Hence this plastic coated neodymium magnet max operating temperature is 70°c.
Some common places of usage for plastic coated neodymium magnets:
– More durable
– Easier to handle
– Will not break or chipped when dropped
– Less likely to break on impact with another magnet
– Less likely to scratch or damage gloss or shiny surfaces
– Less noisy
– More costly
– Weaker compared to neodymium magnets of the same shape, size and grade
– Colour may fade over time if used outdoor (due to constant rain, sunlight, temperature changes)
All magnets and small parts should be kept out of reach of children, this is Not a Toy!
Small shiny or colourful magnets may look attractive to toddlers but will cause serious internal injury or death if swallowed.
Do not buy this if you are uncertain of the safety in your environment of usage.
Do not buy this as a gift for children.
