2、. ADHESIVE, POLYCHLOROPRENE RUBBER BASE - SEALER ESB-M2G173-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a solvent release type, black, polychloroprene rubber adhesive. It has good resistance to weather with an exceptionally long service life. 2. APPLICATION

3、 This specification was released originally for a material flow applied to seal and adhere neoprene and ethylene propylene rubber grommets to either neoprene and/or ethylene propylene rubber vacuum tubing. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part

4、 producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 COLOR Black 3.3 SOLIDS, min 18% (ASTM D 2046, except heat at 102 +/- 3 C for 3 h in a mechanical convection oven) Save sample for next test. 3.4 ASH, based on solids weight, max 10% Test Meth

5、od: Place the crucible containing the solids residue in a cool muffle furnace. Slowly heat to and maintain at 760 +/- 30 C for 1 h. Cool in desiccator and weigh. 3.5 VISCOSITY at 23 +/- 2 C (FLTM BI 111-01, except use a Ford Viscosity Cup 0.25 in (6.4 mm) orifice) 3.5.1 As Received 75-120 s 3.5.2 Ag

7、.1 72 h at 102 +/- 3 C, min 20 lb (89 N) 3.6.2.2 Environmental Cycling (5 cycles), min 20 lb (89 N) . 16 h humidity (95 - 100% relative humidity at 38 C) . 4 h at -29 C . 4 h at 82 +/- 3 C Test Method: Insert the neoprene vacuum hoses into grommet holes designed for the 1/8 in (3 mm) I.D. single hos

8、e and pull through until at least 4 in (100 mm) of hose length extends on each side of grommet holes. Apply cement into the grommet holes around all surfaces of the vacuum hoses with a Plews oiler or other suitable method. Care must be taken to insure adequate cement contact and coverage. . For norm

9、al adhesion, air dry 7 days prior to test. . For aged adhesion, air dry 3 days prior to heat and environmental cycling. . All tests on aged samples shall be conducted at 23 +/- 2 C. Use a ring test fixture to hold the grommet firm and remove each vacuum tubing from the grommet at a jaw separation ra

10、te of 20 in (500 mm) per minute (pendulum or cross head tensile machine, 200 lb (890 N) capacity). Care must be taken to pull tubing in a straight line from grommets. Maximum values obtained are recorded and a minimum average of 4 adhesion values shall be used. 3.7 COLD FLEXIBILITY No cracks permitt

11、ed Test Method: Apply a 0.010 x 1 in (0.3 x 25 mm) wet film of adhesive to a thin sheet of cellophane, polyethylene, or aluminum foil and air dry for 24 h at 23 +/- 2 C. Then condition the specimen in a cold box at -29 C for 4 h and bend 180 around a temperature conditioned 1/4 in (6 mm) mandrel. EN
