|Due to the unforeseen discontinuation of the Permacel 99 tape used in the ASTM D3359 Measuring Adhesion by Tape Test, the industry is forced to find a replacement tape for this method. Within the next several months, ASTM will begin testing to qualify a tape “suitable” to be used in place of the Permacel 99. One of the tapes ASTM will be testing is the PA-280630 (51596) manufactured by Interpolymer Group. Because the testing will take time, we have asked some of our customers to do some testing of their own using the PA-280630 (51596). The findings from our customers so far have been favorable. Therefore, the PA-280630 (51596) tape is what we, The Paul N.Gardner Co., will be selling in place of the Permacel tape until such time as the ASTM testing is complete.
Although we have found the PA-280630 (51596) tape to be “suitable” for this test, users should report in their documentation any differences in the results of their testing compared to past results. Your feedback would be most appreciated.
