The Elcometer 99 Adhesion Test Tape offers users of the Permacel P99 ASTM tape which was discontinued in 2009, a close equivalent when used in accordance with ASTM D3359 – the cross cut adhesion test method for measuring adhesion using the tape test.
Under independent testing completed in 2010, using samples of Permacel P99 adhesion tape (both within and outside of the tape’s expiry date) and another two possible alternate ASTM tapes proposed by the ASTM D01.23 Sub-Committee responsible for the D3359 Standard test method, the Elcometer 99 Adhesion Test Tape, unlike the others tested, has been proven to be a very close equivalent to the Permacel P99 tape.

Effectiveness of the Elcometer 99 ASTM Adhesion Paint Test Tape
The testing was carried out using samples of Permacel P99 tape taken from a roll of tape that has a shelf life that expires in July 2010 and a roll of tape that had already expired. The two other tapes in the trial had been proposed as alternatives to the Permacel P99 tape and were the Scapa 8010-B tape and the Intertape LA-26 tape. The samples of these ASTM tapes were taken from rolls that were within their shelf life. Both of these adhesion tapes are established products for uses other than adhesion testing but were said by the suppliers to be near equivalents to the Permacel P99 tape.
The independent test results in Table 1 clearly show that on average the Elcometer 99 adhesion tape has a peel adhesion strength that is within 4% of the average peel strength of the Permacel P99 ASTM tape. The alternative ASTM tapes were 67.8% higher and 21.4% lower than the average for the Permacel P99 tape making the Elcometer 99 tape the closest match for the tapes that were tested.
