Product Description
3M™ Bumpon™ Protective Products are pressure sensiti v e adhesi v e-back ed polyurethane
products that can be used as feet, stops, spacers, and protectors in many applications.
The urethane is a durable, resilient elastomer. The aggressive, high tack pressure
sensitive adhesi ve is protected with a release liner making application fast and easy.

exhibits:
• Excellent skid resistance
• Long aging resiliency – will not crack or harden
• Abrasion resistance
• Resistance to marring and staining
Application Ideas
Use almost anywhere slamming, scratching, nicking, scuffing, marring, sliding,
vibration, or noise could be a problem for your product.
• Feet on the bottom of blenders, desk top calculators, electronic cabinetry, telephones,
keyboards, foot pedals, scales, clocks, speakers, dispensers, and computers.
• Stops for cabinet doors, lids, and drawers.

Notes:
1
Two important laws of friction applicable to Bumpon products are: (1) Friction is independent of the area of contact
between solids and (2) friction is proportional to the load between solid surfaces. Thus, if the load (weight) is doubled the
force required to cause sliding is also double. This is e xpressed mathematically as follows: Sliding Force = Mkx weight.

These properties were run on sheet material from the same materials as the individual Bumpon products

*Some Bumpon SJ-5700 Series custom products may use other adhesives in their construction.
1) Natural Rubber (R-30) - Used in the construction of 3M™ Bumpon Protective Product Series SJ-5000,
SJ-5500, and SJ-5700, this high tack adhesive provides excellent initial adhesion. The adhesive has the
capability of providing excellent adhesion to a wide variety of surf aces, including many low surface energy
surfaces such as polypropylene, polyethylene, and powder coated paints. This adhesive system shows
reduced shear properties at elevated temperatures.
2) Acrylic (A-20) - Used in the construction of 3M™ Bumpon Protective Product Series SJ-5200, SJ-5300, and
SJ-5400, this high strength adhesive system provides excellent shear strength properties. The adhesive has
the capability of providing excellent adhesion to many high surface energy substrates such as metals, ABS,
polycarbonate, and acrylic. When adhesion is required on low surface energy/substrates (e.g., polyprop ylene,
polyethylene, etc.), acrylic-based adhesives do not perf orm as well as rubber-based adhesiv es.
3) Synthetic Rubber (R-25) - Used in the construction of 3M™ Bumpon Protective Product Series SJ-6100,
this very high tack adhesive system provides excellent initial adhesion. The adhesive has the capability of
providing excellent adhesion to a wide variety of surfaces, including many low surface energy surfaces such
as polypropylene, polyethylene, and powder coated paints. This adhesive system shows reduced shear
properties at elevated temperatures.

Application Techniques
To obtain maximum adhesion, surfaces must be unified, dry, and free of
contaminants. Surface contact is essential to adhesive performance. To maximize
contact on a substrate:
• Clean surfaces with low strength solvent such as isoprop yl alcohol (rubbing
alcohol) or heptane.*
• Apply firm pressure to help increase the cold flow and contact of the adhesive with
the substrate.
• Allow time (dwell) to increase the surface contact and adhesion (see illustrations
below).
*Note: Be sure to follow the manufacturer’s precautions and directions for use when
using solvents.
Environmental
Exposure
Colored and transparent 3M™ Bumpon™ Protective Products are intended for
interior applications where resilience and other physical properties will remain
unchanged. When exposed to UV light for extended periods some slight
discoloration or yellowing may occur.
Bumpon products may be used outdoors in a protected area with some discoloration
possible; colored Bumpon products may chalk.
Simultaneous exposure to high humidity and temperature may degrade (soften) the
Bumpon product urethane.

Considerations
Alignment
Alignment is more difficult
with a rectangular shaped
3M™ Bumpon™ Product
when no recess is provided.
Circular shaped product
Rectangular shaped product
Point of Contact
The point of contact
provides either a large
contact area or a very
small (point) contact area
depending on the shape
of the Bumpon product.
Flat
Hemisphere
• Increased load capacity
• Better wear resistance
• Increased sound dampening
• Increased energy absorption
(side view) (side view)
Profile
The profile is defined
by the height and the
diameter (or width) of
the Bumpon product.
Low Profile
High Profile
• Increased load capacity
• Less susceptible to being
sheared off substrate
• Better hear dissipation
• Not recommended if sideways
shearing is possible
Recess
A recess is not necessary;
however, there are several
benefits to providing a recess.
• Provides target area for the Bumpon product during attachment process
• Improves adhesion performance: impact absorption and shear strength
• Provides neater appearance
• Provides uniform location
(top view) (top view)
Shelf Life
Shelf life is 18 months from date of manufacture when stored in original cartons at
60-80°F (15-27°C) and 40-50% relative humidity.
