Adhesive N42 Neodymium Magnet - 50mm X 10mm X 2mm Thick - 5.5Kg Pull - Pack Of 4

N42 refers to the grade of the Neodymium magnet, indicating its magnetic strength. Higher numbers generally signify stronger magnets.

The acrylic adhesive requires between 24 to 32 hours to reach its maximum bond strength after application.

Each magnet can support up to 5.5kg vertically when in flush contact with a mild steel surface. Ensure the surface and application method are suitable for the weight.

The adhesive works best on smooth, non-porous surfaces such as finished wood, plastic, metal, glass, and painted surfaces. It may not adhere well to fabric, unfinished wood, or very rough surfaces.

The magnets themselves have a corrosion-resistant coating. However, the adhesive may lose effectiveness if submerged in water for extended periods. They are suitable for dry or mildly damp environments.

The adhesive side is not magnetic. To attract two magnets, you must place the non-adhesive (magnetic) sides of each magnet towards each other, ensuring opposite poles align.

While the coating offers corrosion resistance, prolonged exposure to harsh weather conditions may affect the adhesive's long-term performance. Use in protected outdoor areas is recommended.

Ensure the surface is clean and ferrous. Verify the adhesive has fully cured (24-32 hours). Check that you are using the magnetic face and not the adhesive side against the surface.

Clean the surface thoroughly before application. Ensure the surface is not porous, oily, or excessively textured. Press firmly during application and allow full curing time.

Handle magnets by the edges to slide them apart rather than pulling directly. Keep a barrier like a piece of cardboard between them when storing if separation is difficult.

Handle magnets carefully to avoid impacts. If chipped, the magnetic strength may be slightly reduced, but it should still function if the coating is intact. Discard if significantly damaged.
