Pres-On PB7 Adhesive Backed Hemispherical Polyurethane Molded Bumpers have a rounded, dome-like shape that absorbs shock, protects against vibration, and prevents slipping, sliding, and skidding. Made of 100% polyurethane coated with an aggressive rubber adhesive, Pres-On’s bumpers do not contain plasticizers, oils or fillers, and will not mar, scratch, or stain surfaces. Plus, they’re easy to apply. Simply peel away the disposable backer paper and place the bumper where protection is needed.

Application Notes

To obtain a maximum bond, surfaces need to be smooth, non-porous, clean, dry and free of all debris, oils and solvents. Clean the surface with a low strength solvent such as isopropyl alcohol (rubbing alcohol) or heptane. Follow solvent manufacturer’s precautionary warnings and suggested handling procedures when using solvents. Bend pad slightly grasping bumper on sides without touching the adhesive. Apply to surface with enough pressure to ensure a complete bond. Allow a dwell time of 24 hours before exposing to heavy force or weight. The composition of this product contains no migratory plasticizers of any kind, which would mar surfaces of contact. Users should evaluate the suitability of our Bumpers for a specific application under actual conditions.
