*Bumpon SJ5300 series identifies transparent products.
Note: All dimensions ±0.02 inches or ±0.5 mm measured without the adhesive liner.
Note: Dimensions for Bumpon SJ6115 and Bumpon SJ6125 ±0.005 inches (±0.13 mm) for diameter ±0.015 inches (±0.38 mm) for height measured without
adhesive liner. Bumpon Top Hat products were created as an optional, non-skid foot shape, to be used in a recess (see page 7). They provide high
resistance to removal, knock-off or shearing, when used in conjunction with a recessed location.
*Continuous molded strip can be cut by the customer to a specific length. The surface has lines that appear every 9" on the strip.

Typical Physical Properties and Performance Characteristics
Note: The following technical information and data should be considered representative or typical only and should
not be used for specification purposes.
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 expressed
mathematically as follows: Sliding Force = Mk x weight.
2
These properties were run on sheet material from the same materials as the individual Bumpon products
3
Reference test for 24 hours. Results may vary for different product application conditions.
4
When ASTM method is listed, data was collected in accordance with ASTM test method.

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 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 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.

Storage and Shelf Life
The shelf life of 3M™ Bumpon™ Protective Products is 18 months from the date of manufacture when stored in the
original packaging materials and stored at 16-27°C (60-80°F) and 50% relative humidity.
Product Selections Considerations
Alignment
Alignment is more difficult
with a rectangular shaped
3M™ Bumpon™ Protective
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.
