Customized High-Quality 3M Adhesive Magnets

Stanford Magnets can supply a wide range of customized 3M Adhesive backing Magnets according to requests.

* 3M 486 adhesive backing for best adhesion;

* Quick release tab for fast and effective liner removal;

* Strongest magnet material available;

* Maximum operating temperature 80°C.

3M Adhesive Backed Magnets Description

The 3M Adhesive Magnets are magnets with a protective backing strip – simply remove the protective backing strip and press the sticky back magnets neodymium disc magnets onto the item you want to adhere to.

The adhesive layer is placed on one magnetic pole. So a North described adhesive-backed NdFeB disc magnet has the magnetic North pole visible and the magnetic South pole has the adhesive backing.

A South-described adhesive-backed Neodymium disc sticky magnet has the magnetic South pole visible and the magnetic North pole has the adhesive backing.

How to Use 3M Adhesive Backed Magnets

Clean the surface where you will apply the magnet (e.g., walls, plastic, glass, metal cabinets) with alcohol or a mild cleaner to ensure it is oil-free, dust-free, and dry. Rough surfaces should be lightly sanded smooth.
Expose the 3M adhesive surface.
Press the adhesive side firmly against the target surface for 10–20 seconds. Avoid applying any force or load for 24 hours to allow the adhesive to fully cure.

Precautions

Although 3M adhesive has strong holding power, it requires a smooth, clean, dry, and flat surface to achieve the best results. Applying it to uneven or chalky lime walls will significantly reduce adhesion. Strong adhesive backed magnets are made of neodymium, which is not bendable and can break or chip upon impact.

3M Adhesive Magnets Applications

3M adhesive magnets are used more and more in our daily life.

Home and Office: For hanging signs, mounting tools or kitchen utensils, and organizing cables.
Retail and Display: For attaching signage, nameplates, and displays to various surfaces without damaging them.
Automotive: For mounting accessories or decorations inside vehicles.
Electronics: In devices where a secure closure is needed without screws or mechanical fasteners.

It is made up of a neodymium magnet and high-quality 3M self-adhesive tape.

Neodymium magnet, as the most powerful magnet so far, really makes a difference. it is strong and flexible.

Flexible means it can be machined into different shapes, and sizes, with counter holes, or edge and corner processing.

We can do custom magnets to meet your requirements.

FAQ

What are 3M adhesive backing magnets?

3M adhesive backing magnets are permanent magnets (often neodymium, ferrite, or flexible rubber magnets) that have a layer of 3M brand adhesive tape applied to one side. This allows the magnets to be easily attached to non-magnetic surfaces.

What types of magnets come with 3M adhesive backing?

Neodymium Magnets: High-strength magnets ideal for applications requiring a compact and powerful magnet. Ferrite Magnets: Cost-effective magnets suitable for a wide range of applications, offering decent strength and resistance to demagnetization. Flexible Rubber Magnets: Versatile and can be cut to size, perfect for lightweight attachments and crafts.

What are the benefits of using 3M adhesive backing magnets?

Easy to Use: No need for drilling or screws, making installation quick and clean. Strong Adhesive: 3M adhesives are known for their high quality, ensuring a secure bond to various surfaces. Versatility: Can be used on a wide range of surfaces, including metal, plastic, wood, and more. Flexibility: Available in various shapes, sizes, and magnet types to suit different applications.

What is the difference between flexible adhesive backed magnets and rigid strong adhesive backed magnets?

Flexible magnets are like rubber – they can be bent and cut, but have weak magnetic force, making them suitable for holding lightweight items. Rigid magnets are made of neodymium – they are hard and brittle, have strong magnetic force, and are suitable for hanging heavy objects.

Are both sides of a 3M adhesive backed magnet equally magnetic?

No. The side with the adhesive has very weak magnetism (about 50 Gauss), which is designed to make it easy to stick to non-metal surfaces without attracting randomly. The other side without adhesive is strongly magnetic (about 380 Gauss) and is used to attract iron objects or another magnet. When using, be sure to use the non-adhesive side to attract the target object.

Can 3M adhesive backing magnets be removed?

While 3M adhesive is designed for a strong and lasting bond, it is possible to remove the magnets with careful effort. You can use a hairdryer to apply hot air to the adhesive area for 30–60 seconds to soften the adhesive. Then, slowly separate the magnet from the edge using a plastic pry tool or a thin string.

Are there any surfaces that 3M adhesive backing magnets should not be used on?

It's best to avoid applying these magnets to surfaces that are porous, highly textured, or subject to frequent moisture exposure, as these conditions may weaken the adhesive bond. Additionally, some plastics or painted surfaces may be damaged upon removal.

How strong are 3M adhesive backing magnets?

The strength of the magnet itself depends on the type of magnet and its size. Neodymium magnets offer the highest strength, followed by ferrite and then rubber magnets. The adhesive strength will depend on the surface quality and how well the adhesive is applied.

I want to stick two non-metal plates together using adhesive backed magnets. How do I do it?

You will need two adhesive backed magnets to work together. Place the non-adhesive sides of the two magnets facing each other, and stick each magnet onto one of the non-metal plates you want to join.

Can 3M adhesive backed magnets be used outdoors or in humid environments?

Not recommended. Under long-term exposure to high temperatures (above 60°C), humidity, rain, or direct sunlight, the 3M adhesive tends to age and lose its holding power. If outdoor use is necessary, we recommend using specialized weather-resistant VHB tape magnets or adding mechanical fasteners.

Can small sticky back magnets be customized?

Yes, they can be customized in terms of size, shape, thickness, color, magnetic strength grade, etc., but there are minimum order quantity requirements.
