2、Inc. PRIMER, ANAEROBIC ADHESIVES ESW-M2G159-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a surface primer and cleaner. When applied by spray, brush, or dip to metal substrates, it shall cause polymerization of the applied anaerobic adhesive, after assembly o

3、f the parts and normal room temperature cure. 2. APPLICATION This specification was released originally for a material used to accelerate room temperature cure (polymerization) of the anaerobic adhesive. Accelerated cures provide for defixturizing of parts in a matter of minutes rather than several

4、hours. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1 QUALIFICATION REQUIREMENTS 3.1.1 Color Yellow 3.1.2 Specific Gravity 1.12 - 1.28 (ASTM D 2

5、111, Method “C“) 3.1.3 Viscosity at 23 +/- 2 C 0.5 - 2.0 cP (mPa.s) (ASTM D 445) 3.1.4 Solids 1.5 - 2.0% (Using a platinum crucible, heat sample at 102 +/- 3 C for 3 h; save sample for ash test) 3.1.5 Ash, max 0.01% (Place the crucible containing the solids residue in a cool muffle furnace. Slowly h

6、eat to and maintain at 760 +/- 30 C for 1 h. Cool in desiccator and reweigh) ENGINEERING MATERIAL SPECIFICATION ESW-M2G159-A Page 2 of 3 Copyright 2014, Ford Global Technologies, Inc. 3.1.6 Quality On standing at or below room temperature, the material may show slight precipitation. However, on warm

7、ing to 27 +/- 1 C and shaking, the material shall be clear, homogeneous, free from foreign materials and properties detrimental to normal production operations. 3.1.7 Locking Strength, min 100 lb-in (12 N.m) Test Method: Using fine threaded nuts and bolts described in FLTM BV 12-1, apply the primer,

8、 ESW-M2G159-A, to both the nuts and bolts by spray, brush, or dip. Air dry thoroughly, 5 to 10 min. Apply the nuts to the bolts and screw on until approximately 5/8 in (16 mm) of the threaded ends of the bolts protrude. Apply anaerobic compound, ESE-M4G167-A2 by means of the applicator nozzle to com

9、pletely cover the protruding threads of the bolts. Unscrew the nuts over the compound and follow instructions to finalize the assemblies per FLTM BV 12-1. Allow assemblies to rest at 23 +/- 2 C for 30 +/- 1 min. Immediately conduct tests (a) through (c) per FLTM BV 12-1, as follows: Test (a) Test pe

10、r para 3. Test (b) Substitute ESW-M2C33, Automatic Transmission Fluid for the 50/50 water and long life coolant mixture, and reflux for 168 h at 149 +/- 3 C and test per para 4. Test (c) Heat for 2 h at 149 +/- 3 C instead of 88 +/- 3 C and test per para 4. 3.1.8 Storage Stability An increase in vis

11、cosity of 50% or more (para 3.1.3) and/or failure of the compound to meet the locking strength (para 3.1.7) shall constitute excessive deterioration and shall dictate rejection of the material. Test Method: Condition a bottle of the primer in a mechanical convection oven maintained at 49 +/- 1 C for

12、 10 days. After cooling to 23 +/- 2 C re-determine the viscosity (para 3.1.3) and the locking strength (para 3.1.7 test (a) only). 3.2 ACCEPTANCE REQUIREMENTS Of the above qualification tests, material from each batch produced by the manufacturer shall be required to pass only the following tests fo

13、r acceptance: 3.1.1, 3.1.2, 3.1.3, 3.1.4, 3.1.5, 3.1.6, and 3.1.7 test (a). ENGINEERING MATERIAL SPECIFICATION ESW-M2G159-A Page 3 of 3 Copyright 2014, Ford Global Technologies, Inc. 5.
