Exposure to the Environment
BumperStops are intended for interior applications where physical properties will remain unchanged. When used externally for extended periods, some discolouration as well as loss of adhesion may occur.
Load Tolerance Information
SuperSoft BumperStops are not recommended for load bearing
applications, as they are manufactured from a softer than usual
polyurethane material and are intended for door dampening applications only.
If customers wish to use this product for such applications they should
be aware that much lower values will be achieved. Please refer to the
chart below before use.

Adhesive Considerations
Please refer to the chart which illustrates the relative adhesion properties of the adhesive systems used in BumperStops.
In general terms, allow time (dwell) to increase the surface contact and adhesion. Please note that acrylic based adhesives generally require longer dwell times than rubber based adhesive.
Applying BumperStops
It is important to remember that, as with any self adhesive product, the surface to which you are applying BumperStops must be clean, dry and free from dust and dirt. Therefore, to gain maximum adhesion, clean the surface with low strength solvent and allow to dry thoroughly. Please
follow solvent manufacturers’ instructions for safety. The information provided above have been gained under laboratory conditions, therefore customers must test BumperStops themselves to ensure suitability for intended applications.
All BumperStops are RoHS and Wee compliant.
