SPECIAL RECOMMENDATIONS
· Recommended as a replacement for Scotch Tape 467 (same basic properties, but better temperature and solvent resistance). · When used to bond fragile materials such as Second Surface Mirrors (SSM), the tape must be applied first on the structure side. The liner is then removed and a suitable shape SSM bonded. If tape is already applied to the back of the SSM (as in some Sheldahl products), the liner must be removed with the utmost care so as to avoid stresses on the SSM · Availability in Europe is limited when purchased quantity is very small. Maximum width is 122 cm. · Not to be used when peel forces are applied.
