2 date : august 2001 double coated polyethylene foam tape 9546 application techniques 1. bond strength is dependent upon the amount of adhesive-to- surface contact developed. firm application pressure develops better adhesive contact & thus improves bond strength. 2. to obtain optimum adhesion, the bonding surfaces must be clean dry and well unified. a typical surface cleaning solvent is isopropyl alcohol. use proper safety precautions for handling solvents. 3. ideal tape application temperature range is 21c to 38c (70f to 100f). initial tape application to surfaces at temperatures below 10c (50f) is not recommended because the adhesive becomes too firm to adhere readily. however once properly applied low temperature holding is generally satisfactory. 3m and scotch-mount are trademarks of the 3m compan y. values presented have been determined by standard t est methods and are average values not to be used f or specification purposes. our recommendations on the use of our products are based on tests believed to be reliable but we would ask that you conduct your own tests to determine their suitability for your a pplications. this is because 3m cannot accept any responsibility or liability direct or consequential for loss or d amage caused as a result of our recommendations. tapes & adhesives ? 3m united kingdom plc 1996 3m united kingdom plc 3m house, 28 great jackson street, manchester, m15 4pa product information : tel 0870 60 800 50 fax 0870 60 700 99 3m ireland 3m house, adelphi centre, upper georges street, dun laoghaire,co. dublin, ireland customer service : tel (01) 280 3555 fax (01) 280 3509
