SCOPEThe material defined by this specification is a rubber based, moisture resistant, adhesion primer.2. APPLICATIONThis specification was released originally for materials used for prim

3、ing the painted surfaces of thepinch weld flange prior to the application of ESB-M3G95 Elastomeric Bonding Tape for windshield andbacklite installations.3. REQUIREMENTS3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requi

4、rements For Production Materials (WSS-M99P1111-A). 3.2 COLOR Black 3.3 HIDING POWER The primer when applied in a 0.003 - 0.005 in (76 - 127 micrometre) film thickness shall completely black-out the color of the painted metal surface. 3.4 BRUSHABILITY The primer when hand brushed on painted surfaces

5、shall level with no evidence of brush marks, voids or bare spots to the extent that the painted metal undersurface is visible. The material under test shall be equal to or better than the current approved production material for smoothness when applied under identical conditions. When acrylic lacque

6、r is employed as the color coat, the same procedure is required. 3.5 VISCOSITY (FLTM BI 111-01, #4 Ford Cup) 3.5.1 Normal 40 - 60 s 3.5.2 Aged (2 weeks at 49 +/- 1 C) 40 - 60 s NOT TO BE USED FOR NEW DESIGN2014 12 08 N Status No replacement named L.

Save sample for next test.) 3.7 ASH CONTENT (Solids Weight), max 25 % The tolerance for any one supplier shall be +/- 2 % based

8、on the result obtained from his original approved production sample. Test Method: 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 a desiccator and weigh. 3.8 WEIGHT/VOLUME The weight tolerance for any one supplie

9、r shall be +/- 0.2 lb/gal (0.024 kg/L) based on the recorded weight of the original approved production sample. (See para 4.3) 3.9 DRYING RATE, max 5 min Test Method: Apply a 0.003 - 0.005 in (76 - 127 micrometre) film of primer to a steel panel coated with white or light blue ESB-M32J100 quality en

10、amel. Determine the drying rate of primer by applying light finger pressure at 23 +/- 2 C. Prior to testing, clean oils from fingers by using denatured ethyl alcohol ESF-M8B12-A. The primer surface may be tacky, however, there shall be no transfer to the finger. Where acrylic lacquer is employed as

11、the color coat, the same procedure is required. Save panel for next test. 3.10 MIGRATION STAIN No Migration Stain Test Method: Expose the painted panel prepared in para 3.9 for a total of 96 h in the fluorescent sunlamp cabinet described in FLTM BO 115-01. 3.11 YIELD STRENGTH, 100 % Cohesive Failure

16、eds the 72 h limit, apply a second coat of primer over the original coat. 3.14 STORAGE STABILITY This adhesion primer must be stored away from all sources of heat such as ovens, direct sunlight, etc. This fluid primer when stored in excess of 3 months must be recirculated or agitated prior to initia

17、l use. The storage period for this adhesion primer shall not exceed 9 months at 49 C maximum. If this adhesion primer is stored at temperatures below 19 C, it must be conditioned at 23 +/- 2 C for 48 h prior to usage. 3.15 QUALITY The material shall be a smooth, homogeneous mixture, free from foreig
