Waterproof Magnets FAQ
What are waterproof magnets?
Waterproof magnets are designed to withstand moisture and prevent corrosion by utilising protective coatings. Our products are treated with high-quality epoxy or PTFE coatings, ensuring long-lasting performance in damp or harsh conditions.
What coating options are available?
Our waterproof magnets are available with either epoxy or PTFE coatings. Both options provide excellent resistance to water and corrosion, with the epoxy coating offering a rugged, durable finish and the PTFE coating delivering low friction and additional chemical resistance.
What are the typical applications for these magnets?
Our epoxy and PTFE coated waterproof magnets are widely used in marine environments, outdoor signage, electronic devices and various industrial settings. They are particularly effective in applications where moisture, high humidity, or frequent cleaning might otherwise compromise magnet strength.
How do I choose the right waterproof magnet for my project?
Consider factors such as the specific coating required (epoxy for extra durability or PTFE for low friction and chemical resistance), the magnetic strength needed, and the size that suits your application. Reviewing detailed product specifications or consulting with our UK support team can help ensure you select the perfect magnet for your project.
