Features
✅ Durable White Epoxy Coating
These high performance rectangular neodymium magnets are coated with a smooth, bright white epoxy layer. Unlike bare or nickel-plated magnets, this epoxy coating ensures long-lasting durability even in humid, outdoor, or corrosive industrial environments. The white coating is cleaner and more aesthetically pleasing than standard black epoxy coatings, making it ideal for aesthetically pleasing applications such as home organization, office supplies, or consumer products.
✅ Single-Sided Adhesive for Easy Installation
These white epoxy coated magnets come with high quality adhesive (such as 3M adhesive), allowing for quick and secure attachment to both metal and non-metal surfaces without the need for screws, drilling, or additional tools. This saves installation time and prevents damage to vulnerable surfaces. The strong adhesive ensures a strong and reliable bond for a long time under normal use conditions.
✅ Versatile Applications
These white block adhesive neodymium magnets are versatile and suitable for a variety of applications. The single-sided adhesive makes them easy to attach to flat surfaces, while the durable epoxy coating ensures long-lasting functionality and appearance. These are perfect for designers, makers, and engineers who need compact solutions that combine strength and convenience.
