Product Description

3M Bumpon SJ Series Self-Adhesive Bumpers 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. The plasticizer-free urethane composition of the bumpons exhibit excellent skid resistance, long aging resiliency (will not crack or harden), abrasion resistance and resistance to marring and staining. Use 3M Bumpons almost anywhere slamming, scratching, nicking, scuffing, marring, sliding, vibration, or noise could be a problem for your product.

Uses & Applications

  • Feet on the bottom of blenders, desk top calculators, electronic cabinetry, telephones, keyboards, foot pedals, scales, clocks, speakers, dispensers and computers.
  • Stops for cabinet doors, lids and drawers.
  • Spacers for picture frames to provide alignment; for auto glass as an aid in assembly.
  • Protectors for stacked glass and metal sheets.

The tapered square bumpers are typically used for larger appliances and electronics while the smaller hemisphere and cylindrical shaped bumpons are usually used for phones, speakers and keyboards. The hexagon shaped bumpons are made from soft foam rollstock and are used in woodworking where a softer material is preferred. The quiet bumpons have a hexagonal cone shape and are ideal for use on cabinets and drawer fronts.

Application Instructions

  1. Apply to any smooth, flat surface such as glass, metal, wood, smooth plaster, tile, etc.
  2. For best results surfaces must be clean and dry. Clean with a low strength solvent like isopropyl alcohol (rubbing alcohol) or heptane (white gas) with a clean cloth.
  3. Do not attempt to use on fabric, course concrete walls, rough sand finishes, loose paint or rough wallpaper.
  4. Remove paper liner from back of bumper. Avoid touching adhesive with fingers. Place bumper on desired location and press firmly to insure contact of adhesive.

3M Scotch SJ Series Bumpon Self-Adhesive Bumpers
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
acrylic
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
silicone
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
