Surface Preparation: The surface on which the tape is to be used must be clean, dry and free from grease and dust. Remember that pressure sensitive adhesive must be applied with the maximum possible pressure in order to achieve maximum adhesion levels. The recommended application temperature is between 15ºC and 25ºC.

Storage: Tapes stored below the minimum application temperature will require warming up to that level before use. Up to 24 hours may be required for this to take place.

Note: The above figures represent average values. Actual figures can vary. The selection and application of a tape is the responsibility of the buyer. Tape should be stored at room temperature and should not be exposed to sunlight. We reserve the right to make changes without notice to our products and specifications.
