Adhesive Choices
Natural Rubber (R-30) – Used in the construction of 3M™ Bumpon™ Protective Product 5000, 5500, and
5700 series. 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 3M™ Bumpon™ Protective Product 5300, and 5400 series. 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 3M™ Bumpon™ Protective Product 5200, 6100,
6300, 6500 and 6700 series. 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, and powder coated paints. This adhesive system shows reduced
shear properties at elevated temperatures.

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.

(side view)
• Increased load capacity
• Better wear resistance
• Increased sound damping
• Increased energy absorption
• Increased load capacity
• Less susceptible to
being sheared off substrate
• Provide target area for the Bumpon product during
attachment process
• Improve adhesive performance, impact absorption and
shear strength
• Provide neater appearance
• Provide uniform location
• Better heat dissipation
• Not recommended if
sideways shearing is possible
(top view)
Profile
The profile is defined by the
height and the diameter or
width of the Bumpon product.
Recess
A recess is not necessary.
It can be beneficial to:

Considerations
Feet have a low coefficient
of friction allowing them to
be used as glides for use
under computers and small
appliances.
