SCOPE The material defined by this specification is a two part, no mix, thixotropic adhesive. It is used by
3、 applying the resin to one surface and the activator to the other. The surfaces are brought together and the adhesive cures rapidly with light pressure. 2. APPLICATION This material was released originally as an adhesive to bond permanent magnets in windshield wiper motors. 3. REQUIREMENTS 3.0 STAND

(A) Cover one slide about 25 mm with activator using a brush. Let the solvent flash off for 20 - 30 s. (B) Place a small 3.2 mm diameter drop
9、of adhesive 12.7 mm from the end of the other slide. (C) Press the two slides together with strong finger pressure (the adhesive will spread out and mix with the activator). (D) Carefully and gently test the ends of the slides for movement every 5 seconds. Record the time when there is resistance to
10、 movement. 3.8 TENSILE STRENGTH, min 14 kPa (ASTM D 1002) ASTM D 1002 Tensile Test (A) Scribe 12.7 mm overlap marks on ASTM D 1002 steel test coupons. (B) Apply activator to one steel coupon. (C) Apply a 1.6 mm bead across the middle of the bond area on the mating steel coupon. (D) Assemble and clam

12、ck) Cold rolled steel test coupons are prepared per ASTM D 1002. After a 24 h 24 C cure they are subjected to the following thermal shock cycle: (A) 1 h at 150 C. (B) Immediately drop into ice water. Allow to cool for 10 minutes. (C) Immediately repeat (A) and (B) for a total of 3 cycles. (D) Allow to warm up to 24 C and test for tensile strength on a standard tensile tester at 12.7 mm per minute.
