SPECIAL RECOMMENDATIONS

          All tapes are a standard length of 105 ft 5%. (Maximum length available is ca. 160ft.).

          All tapes are wound on a 3 0.5 in. diameter core.

          Recommended shelf life is a period of one year after date of manufacture, when tape has been stored properly at normal room temperature.

          Kapton HN / Y966 acrylic pressure-sensitive tapes can be perforated.

          This product is also available with Dunmore's 'corrosion-resistant coating'.

          'Y966' acrylic P/S release liner can also be applied to the metallised surface to provide second-surface mirror capabilities, if desired.

          'Y966' acrylic P/S release liner can also be applied to 51, 76 and 125 mm thick films.

          The full Dunmore part number must be designated for precise material description.

          'Y966' high~temperature acrylic tapes are primarily used when high-temperature performance and excellent bond strength are required.

          Solar absorptance value is measured on the aluminised side only.
