35、ementabilitySeal the treated surface of the material by the application of controlled heat, pressure, and time of dwellto an adhesive-coated strip of aluminum sheet. Measure the peel strength at a peel angle of 180, and a speed of 30.5 cm/min (12in./min).14.6.1 Procedure for Preparation of Adhesive-

36、Coated Aluminum:14.6.2 Coat sheets of aluminum 254 by 254 mm (10 by 10 in.) evenly with No. 68040 adhesive7 using a No. 24 “Draw Down”rod and allow to dry in air for 8 h. The thickness of coating is not critical but it is important that the coating be smooth andbubble-free. Use methyl ethyl ketone t

37、o thin the adhesive if necessary, and for cleaning the equipment.14.6.3 Cut the coated sheets into strips 38.1 by 127 mm (1.5 by 5 in.) and store in a desiccator. It is not advisable to preparemore than a 2 or 3-month supply of coated aluminum at one time, as the adhesive slowly crosslinks in time a

38、nd seal strength valuesare lowered.14.6.4 Cut five 25.4 by 127-mm (1 by 5-in.) sample strips evenly spaced across the width of the film sample. The film mustbe free of fingerprints and contamination.14.6.5 Place each film specimen on a strip of the coated aluminum with the treated surface facing the

39、 adhesive. Seal the stripsin the heat sealer with the aluminum strip facing the heated jaw and the film facing the silicone rubber pad. Set the sealer at 10-sdwell time and 138-kPa (20-psi) jaw pressure. Set the temperature in accordance with Table 3.14.6.6 Make the seal, and after the specimen has

40、cooled to room temperature, determine the peel strength in a tension tester,at a peel angle of 180.14.6.7 Calculate the average seal strength in grams per inch from the five determinations.14.6.8 PrecisionIn a laboratory test, a sample tested by this test method had an average of 1316 g/in. with a 1
