Presentation of the 3M™ Bumpon™ SJ5302 adhesive bumper

The 3M™ Bumpon™ SJ5302 adhesive bumper is a urethane shock-absorbing pad with an integrated permanent acrylic adhesive. It protects surfaces against impacts, scratches, and vibrations, without the need for screws or tools.

Its low hemispherical profile allows it to blend discreetly into any type of equipment. It is suitable for industrial applications as well as electronic products, furniture, or household appliances.

Adhesive technology and constituent materials

The translucent urethane body absorbs repeated impacts without suffering permanent deformation. This material offers good resistance to light oils, moisture, and common temperatures.

The 3M™ high-performance acrylic adhesive ensures an immediate and durable bond on most clean and smooth surfaces: metal, plastic, glass, lacquered wood.

Main benefits of the SJ5302:

• Translucent urethane body, discreet on all surface colors
• Permanent acrylic adhesive, tool-free application
• Good resistance to repeated impacts and vibrations
• Compatible with painted, lacquered, metal, and plastic surfaces

Technical characteristics and specifications of the SJ5302

The Bumpon™ SJ5302 is a transparent polyurethane adhesive bumper, designed to protect surfaces while remaining virtually invisible.

Its shape is hemispherical, with a diameter of 9.5 mm and a height of 3.2 mm. A compact format, ideal for applications where space must be kept to a minimum.

The back is equipped with a 3M permanent acrylic adhesive, ensuring a reliable bond on most smooth surfaces: metal, glass, plastic, lacquered wood.

Polyurethane offers good compression resistance and abrasion resistance. The bumper absorbs shocks, reduces vibrations, and protects contact surfaces from scratches.

The product is resistant to oils, common solvents, and UV rays, allowing it to maintain its properties over time, even when exposed to light.

Product	Shape	Diameter	Height	Material	Color	Typical usage
SJ5302	Hemisphere	9.5 mm	3.2 mm	Polyurethane	Transparent	Discreet protection, electronics, furniture
SJ5303	Hemisphere	12.7 mm	4.8 mm	Polyurethane	Transparent	Larger surfaces, doors, housings
SJ5012	Hemisphere	9.5 mm	3.2 mm	Polyurethane	Black	Industrial equipment, drawer bottoms
SJ5076	Square	19.1 mm	6.4 mm	Polyurethane	Transparent	Large panels, display cases, heavy doors

Comparison: SJ5302 versus other references in the 3M™ Bumpon™ SJ5300 range

The 3M™ Bumpon™ SJ5300 range includes several references that share the same base: a transparent polyurethane elastomer, a hemispherical profile, and an integrated permanent adhesive.

What changes from one reference to another is primarily the size of the bumper: diameter, height, and therefore contact surface area. The SJ5302 is positioned as a compact and discreet format, ideal for applications where visual clutter must be kept to a minimum.

Reference	Diameter (mm)	Height (mm)	Typical usage
SJ5302	9.5	3.2	Electronics, housings, small equipment
SJ5303	12.7	4.8	Furniture, panels, medium equipment
SJ5307	19.1	7.9	Machines, heavy equipment, large surfaces
SJ5308	25.4	9.5	Heavy loads, industrial applications

The SJ5302 is particularly suitable for small-sized surfaces where a larger bumper would overlap or detract from the aesthetics of the finished product.

Its 3.2 mm height offers sufficient cushioning for light impacts and common vibrations, without unnecessarily raising the placed part.

For heavier loads or larger contact surfaces, references SJ5307 or SJ5308 will be more suitable. The choice therefore depends directly on the weight to be supported and the space available on the part.

Applications and fields of use for the SJ5302 bumper

The 3M™ Bumpon™ SJ5302 adhesive bumper is a transparent, discreet, and versatile hemispherical pad. It sticks in seconds to almost any surface.

Its permanent acrylic adhesive ensures a solid bond on metal, plastic, glass, lacquered or melamine wood. It resists vibrations and repeated impacts without peeling off.

In electronics and computing, it protects the bottom of housings, keyboards, monitors, and office equipment. It prevents scratches on work surfaces and dampens impacts.

In furniture and interior design, it is used on cabinet doors, drawers, flaps, and lids. It reduces closing noise and protects contact surfaces.

It is also suitable for household appliances, measuring instruments, medical equipment, and any product requiring stable and silent support.

Here are the main application sectors:

• Consumer electronics: computers, speakers, chargers, routers
• Office and home furniture: drawers, doors, shelves
• Industry and equipment: control boxes, covers, panels
• Medical and laboratory: measuring devices, trays, sensitive equipment
• Retail and mass distribution: displays, POS advertising, commercial furniture

Its transparency makes it almost invisible on light or dark surfaces. It does not alter the aesthetics of the finished product, making it a preferred choice for industrial designers.

Application tips and best practices for optimal adhesion

The SJ5302 adhesive bumper is simple to install, but a few precautions make all the difference between a hold of a few days and a long-lasting bond.

Prepare the surface first. Carefully degrease with isopropyl alcohol or a suitable solvent. Any trace of oil, dust, or moisture significantly reduces the adhesive strength of the 3M acrylic double-sided tape.

The surface must be smooth, clean, and dry. On porous or highly textured surfaces, adhesion will be lower: perform a prior test.

Apply the bumper by exerting firm pressure for 5 to 10 seconds. This prolonged contact properly activates the adhesive and ensures uniform bonding across the entire base.

Then, allow a curing time of at least 24 hours before subjecting the bumper to mechanical or vibratory stress. The final strength of the 3M acrylic adhesive is reached gradually.

Points to remember:

• Ideal application temperature: between 15 °C and 35 °C
• Avoid freshly painted surfaces or those treated with waxes
• Do not apply under stretching stress or at a forced angle
• On stainless steel or glass, adhesion is excellent without special preparation

Once properly installed, the SJ5302 resists impacts, vibrations, and temperature variations without peeling off or leaving residue on most surfaces.

FAQ - 3M™ Bumpon™ SJ5302 adhesive bumper

1. What is the SJ5302 adhesive bumper concretely used for?

The 3M™ Bumpon™ SJ5302 is a self-adhesive shock-absorbing pad. It is stuck under an object to absorb shocks, reduce vibrations, and protect contact surfaces.

Typical applications: electronic housing feet, appliance covers, drawers, cabinet doors, light industrial equipment.

2. On what surfaces does the SJ5302 adhere well?

The back of the SJ5302 is equipped with a high-performance 3M acrylic adhesive. It sticks effectively to most smooth and clean surfaces: metal, plastic, glass, lacquered wood.

On porous or dusty surfaces, the bond will be less reliable. Prior degreasing is recommended to ensure holding power.

3. Does the SJ5302 resist heat and humidity?

Yes. The polyurethane material of the SJ5302 offers good resistance to moderate temperatures and ambient humidity. It is suitable for demanding indoor environments.

For prolonged exposure to extreme temperatures or water, other references in the Bumpon range may be more suitable.

4. What is the difference between the SJ5302 and other Bumpons like the SJ5012 or SJ5523?

3M™ Bumpons are distinguished primarily by their shape, height, and hardness. The SJ5302 is a hemispherical bumper of compact size with medium hardness.

The SJ5012 is lower and firmer, suitable for tight clearances. The SJ5523 is higher and softer, for more pronounced cushioning. The choice depends on the gap to be filled and the level of damping required.

5. Does the SJ5302 leave marks if removed?

The SJ5302 is designed for permanent bonding. Forced removal may leave adhesive residue or mark delicate surfaces.

If you need a repositionable solution, this product is not the right choice. The Bumpon™ range offers versions with less aggressive adhesive for this purpose.

6. At Dagobert Industrie, is this product suitable for intensive industrial use?

Yes. We offer the SJ5302 precisely because it meets the requirements of industrial environments: reliable mechanical hold, durable material, quick tool-free application.

It is used in production, maintenance, and equipment integration. It is a simple technical consumable, but its 3M quality makes a real difference in the long run.
