Product Description 3M Bumpon protective products are pressure sensitive adhesive-backed
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 adhesive is protected with a release liner making application fast and easy.
Features Bumpon protective products feature a plasticizer-free urethane composition
which exhibits:
• Excellent skid resistance
• Long aging resiliency–will not crack or harden
• Abrasion resistance
• Resistance to marring and staining

Notes:
1Two 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 expressed
mathematically as follows: Sliding Force = Mkx weight.
2These properties were run on sheet material from the same materials as the individual
Bumpon products.

Adhesive Creep vs Temperature
Adhesive Description Natural Rubber (R-30) - Used in the construction of SJ-5000, SJ-5500, and SJ-5700 series products.
This high tack adhesive provides excellent initial adhesion and 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.
Acrylic (A-20) - Used in the construction of SJ-5200, SJ-5300, and SJ-5400 series products. 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., polypropylene, polyethylene, etc.), acrylic-based adhesives do not perform as well as rubber-
based adhesives.
Synthetic Rubber (R-25) - Used in the construction of SJ-6100 series products. This very high
tack adhesive system provides excellent initial adhesion and 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
Information Application Temperature: 40˚F (5˚C) to 125˚F (52˚C)
Service Temperature: Constant: -30˚F (-34˚C) to 150˚F (66˚C)
Intermittent: Up to 225˚F (107˚C)
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 isopropyl 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 illustration below).
*Note: Be sure to follow the manufacturer’s precautions and directions for use when using solvents.

Environmental
Exposure Colored and transparent Bumpon™ 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.
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.

Considerations Alignment
Alignment is more difficult
with a rectangular shaped
Bumpon product when no
recess is provided.
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.
Profile
The profile is defined by the
height and the diameter (or
width) of the Bumpon product.
Recess
A recess is not necessary;
however, there are several
benefits to providing a recess.
• Increased load capacity • Increased sound dampening
• Better wear resistance • Increased energy absorption
• Provides target area for the Bumpon product during attachment process
• Improves adhesive performance: impact absorption and shear strength
• Provides neater appearance
• Provides uniform location
• Increased load capacity • Better hear dissipation
• Less susceptible to being • Not recommended if sideways
sheared off substrate shearing is possible
