*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 Protectiv e 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 surfaces, including many low surf ace 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., polypropylene,
polyethylene, etc.), acrylic-based adhesives do not perform as well as rubber-based adhesives.
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.
