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 Testing performed by 3M; SJ-5300 series Bumpon products are not UL listed.

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 rubberbased 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.

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.

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 60-80F (15-27C) and 40-50% relative humidity. 3M Bumpon Protective Products TM TM FOD# 1537 Molded Shapes SJ-5000 * SJ-5200 * SJ-5300 * SJ-5400 * SJ-5500 * SJ-5700 * SJ-6100 Series Product Selections 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. Technical Information and Data Product Use page 7 of 7 * Increased load capacity * Better wear resistance * Increased sound dampening * Increased energy absorption * Increased load capacity * Less susceptible to being sheared off substrate * Better hear dissipation * Not recommended if sideways shearing is possible * Provides target area for the Bumpon product during attachment process * Improves adhesive performance: impact absorption and shear strength * Provides neater appearance * Provides uniform location The technical information and data, recommendations, and other statements provided are based on tests or experience which 3M believes to be reliable, but the accuracy or completeness of such information is not guaranteed.
