3M™ Bumpon™ SJ5780 Adhesive Bumper

3M™ Bumpon™ SJ5780 adhesive bumper: discreet protection and permanent fixing

The 3M™ Bumpon™ SJ5780 adhesive bumper protects your surfaces against impacts, scratches, and vibrations without leaving a trace. Discreet, it blends into any environment.

Its permanent adhesive ensures a reliable hold on metal, plastic, glass, or wood, even with intensive use.

Made of flexible polyurethane by 3M, it absorbs repeated impacts without deforming or peeling off over time.

Presentation of the 3M™ Bumpon™ SJ5780 adhesive bumper

The 3M™ Bumpon™ SJ5780 adhesive bumper is a transparent polyurethane cushioning pad, designed to protect surfaces and reduce impact noise in everyday life.

Its low-profile hemispherical shape allows it to blend discreetly into any surface. Ideal where aesthetics matter as much as function.

The 3M permanent adhesive backing ensures immediate and durable fixation on most smooth surfaces: glass, metal, plastic, lacquered wood.

Materials and adhesive: what makes the Bumpon™ SJ5780 robust

The Bumpon™ SJ5780 relies on two key components: a polyurethane body and a permanent acrylic adhesive developed by 3M.

Polyurethane offers high compression resistance while remaining flexible. It absorbs repeated shocks without permanent deformation or losing its original shape.

The underside is equipped with a high-performance 3M acrylic adhesive. It ensures immediate and permanent attachment to most smooth surfaces: metal, glass, plastic, varnished wood.

This type of adhesive is formulated to withstand temperature variations and humidity. The bumper stays in place even in demanding environments.

The transparency of the material is a discreet but concrete asset: the bumper blends into the decor on light or glass surfaces without masking the aesthetics of the protected product.

Product	Material	Adhesive	Profile	Typical usage
Bumpon™ SJ5780 (3M)	Transparent polyurethane	3M permanent acrylic	Low hemispherical	Protection, anti-slip, discretion
Bumpon™ SJ5302 (3M)	Transparent polyurethane	3M permanent acrylic	High hemispherical	Enhanced protection, larger spacing
Bumpon™ SJ5076 (3M)	Black polyurethane	3M permanent acrylic	Flat cylindrical	Dark surfaces, industrial use
Generic rubber bumper	EPDM / natural rubber	Standard adhesive	Variable	General use, lower adhesive durability

Applications and fields of use of the SJ5780

The Bumpon SJ5780 is a transparent, discreet, and versatile adhesive bumper. Its hemispherical shape and permanent self-adhesive base make it adaptable to a wide variety of surfaces and contexts.

It installs in seconds, without tools, on almost any material: glass, wood, metal, ABS plastic, acrylic. It is a product that fades visually while doing its job.

Here are the most common uses:

• Surface protection: prevents scratches on worktops, shelves, furniture
• Shock absorption: reduces slamming of doors, drawers, electronic housings
• Stabilization: prevents sliding of devices placed on a surface
• Spacing: creates a gap between two surfaces to avoid direct contact
• Consumer electronics: feet for keyboards, remote controls, speakers, housings

In the industry, the SJ5780 is used to protect control panels, equipment lids, or parts in frequent contact. Its transparency makes it invisible on light or translucent surfaces.

It is suitable for both domestic applications and demanding professional environments, provided that temperatures remain within the standard range of the product.

Comparison: SJ5780 versus other 3M™ Bumpon™ adhesive bumpers

The 3M™ Bumpon™ range includes dozens of references. Choosing the right bumper depends primarily on the desired height, diameter, and hardness.

The SJ5780 stands out for its low hemispherical profile and its transparent color, ideal for applications where discretion is a priority.

Comparison table of main Bumpon™ references

Reference	Shape	Diameter (mm)	Height (mm)	Color	Shore A Hardness	Typical usage
SJ5780	Hemispherical	9.5	2.4	Transparent	~45	Electronics, furniture, glasswork
SJ5012	Hemispherical	12.7	5.3	Black	~45	Housings, lids, heavy equipment
SJ5003	Hemispherical	6.4	2.4	Black	~45	Small devices, keyboards
SJ5076	Cylindrical	19.1	3.2	Black	~45	Large surfaces, doors, panels
SJ5516	Conical	15.7	8.7	Black	~45	Enhanced protection, significant shocks

The SJ5780 is the most discreet reference in the comparison: its compact size and transparent shade make it virtually invisible once installed.

For applications subject to repeated shocks or heavier loads, the SJ5012 or SJ5516 will be more suitable thanks to their greater height.

The SJ5003 remains the only direct competitor in terms of height, but its smaller diameter reduces the damping and contact surface.

Installation tips and best practices for optimal adhesion

The SJ5780 adhesive bumper incorporates a high-performance 3M acrylic adhesive. To get the best out of it, a few simple precautions make all the difference.

Prepare the surface first. Carefully degrease with isopropyl alcohol or a suitable cleaner. Any trace of oil, dust, or moisture compromises long-term adhesion.

The surface must be smooth, clean, and dry. The SJ5780 adheres well to most rigid materials: painted metal, ABS plastic, glass, varnished wood, anodized aluminum.

Apply the Bumpon by exerting firm pressure for 5 to 10 seconds. This direct contact activates the adhesive and ensures a uniform bond over the entire base of the pad.

Then, allow a curing time of 24 hours before subjecting the bumper to repeated mechanical stress. The adhesive reaches its maximum strength after this period.

Some points to remember:

• Recommended installation temperature: between +10 °C and +38 °C
• Avoid porous, textured surfaces, or uncured powder coatings
• Do not apply to a freshly painted surface (wait at least 72 h)
• On curved surfaces, choose a bumper diameter adapted to the curvature radius

Once installed, the Bumpon SJ5780 is permanent: removal usually damages the surface or destroys the bumper. Plan the location carefully before pressing.

FAQ - 3M™ Bumpon™ SJ5780 adhesive bumper

1. What is the difference between the SJ5780 and other Bumpon™ references?

The SJ5780 is a transparent low-profile bumpon, ideal when visual discretion is a priority. Other references such as the SJ5302 (black, higher dome) or the SJ5012 (flat square) meet different needs: more pronounced damping or a larger contact surface.

2. Which surfaces does it stick to really well?

The 3M™ permanent acrylic adhesive adheres to most smooth surfaces: glass, painted metal, ABS plastic, varnished wood, anodized aluminum.

On porous, textured, or slightly greasy surfaces, adhesion will be lower. Cleaning with isopropanol before installation significantly improves the result.

3. Does the SJ5780 resist heat and humidity?

The transparent polyurethane of the SJ5780 supports a temperature range from approximately -40 °C to +70 °C. It resists ambient humidity and light water splashes well.

For prolonged exposure to steam or immersion, prefer a solution specifically designed for humid environments.

4. Can it be removed without damaging the surface?

The adhesive is classified as permanent: removal is possible but may leave a slight trace of glue on some delicate supports (matte paint, raw wood).

On glass or metal, a little isopropyl alcohol is usually enough to clean the residue without damage.

5. Is the SJ5780 bumpon suitable for food or medical use?

The SJ5780 is not certified for direct contact with food or for regulated medical applications. For these uses, 3M™ offers other Bumpon™ references with suitable certifications.

If in doubt, consult the official 3M™ technical datasheet available on our site.

6. What are the thickness and diameter for the SJ5780?

The SJ5780 has a very low profile: approximately 1.6 mm in height for a diameter of 9.5 mm. It is this compact format that makes it invisible in use while ensuring effective protection against scratches and light shocks.
