REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Produc
5、tion Materials (WSS-M99P1111-A). 3.2 PHYSICAL PROPERTIES 3.2.1 Viscosity (FLTM BI 111-01) The enamel viscosity value by color shall be established at I.S.I.R. Tolerance on subsequent batches shall be +/- 6 s #2 Ford Cup or +/- 3 s #4 Ford Cup. 3.2.2 Solids, min 27% (FLTM BI 102-01) The solids conten
6、t is to be run on unreduced paint if its viscosity is lower than 26s #4 Ford Cup at 26 +/- 1 C. If the paints viscosity is higher, adjust the paint viscosity to 26 s #4 Ford Cup at 26 +/- 1 C with a solvent blend agreed to by the manufacturer and user.

The viscosity of the material shall not increase more than 10 s. 3.3 PREPARATI
8、ON OF TEST PANELS Prepare according to the following procedure. 3.3.1 Panels Use RIM or microcellular urethane panels of any convenient size, representative of production material. A smooth surface with no pits or blow holes is required. Solvent wipe panels clean before applying primer. 3.3.2 Painti
9、ng Prepare panels according to paras 3.3.2.1 and 3.3.2.2. 3.3.2.1 Primer and Enamel - Uncatalyzed System Reduce ESB-M6J123-B1 primer surfacer to spray viscosity as recommended by the supplier. Spray sufficient paint to obtain 20 - 30 m dry film thickness. Bake panels approximately 20 min at 121 C to
10、 obtain a surface temperature of 116 C for 10 min. Do not sand. The primer requires the color coat bake for complete cure. Apply ESB-M2J121 elastomeric enamel to one-half of the test panel(s). Bake panels at 121 - 132 C ambient oven temperature for sufficient time to obtain a minimum surface tempera
11、ture of 116 C for 20 min with 15 min at 121 C. Surface temperature shall not exceed 20 min at 121 C. The dry film thickness of the enamel shall be 46 m minimum. 3.3.2.2 Primer and Guide Coat - Catalyzed System (Refer to ESB-M99J307) Apply sufficient ESB-M6J123-C primer reduced per supplier recommend
12、ations to obtain 13 - 20 m dry film thickness. Flash off 3 - 5 min then apply ESB-M6J123-B2, reduced per supplier recommendations, wet on wet over the ESB-M6J123-C primer to a dry film thickness of 15 - 20 m. Bake panels approximately 12 min at 121 C to obtain a minimum surface temperature of 96 C f
13、or 7 min. Cool, then rebake panels at 121 - 132 C ambient oven temperature for sufficient time to obtain a minimum surface temperature of 116 C for 20 min including 15 min at 121 C. Surface temperature shall not exceed 20 min at 121 C. The total dry film thickness shall be 33 m min. ENGINEERING MATE

15、 Center. 3.4.2 Leveling The primer film shall level with a minimum of orange peel. The surface of the material under test shall be equal to or better than current approved production material for smoothness when applied and baked under identical conditions. 3.4.3 Holdout There shall be no evidence o
16、f dulling or strike-in when enamel color coat is applied over unsanded primer. 3.5 FILM PROPERTIES 3.5.1 Adhesion (FLTM BI 106-01) There shall be no chipping, flaking, or loss of adhesion of primer to substrate, primer to primer or primer to enamel. 3.6 DURABILITY PROPERTIES In addition to the follo
17、wing weathering requirement, enameled panels must meet all requirements of ESB-M2J121, Elastomeric Enamel Exterior specification. 3.6.1 Weathering Resistance Panels prepared in accordance with paras 3.3.2.1 and 3.3.2.2 and exposed as follows shall show a minimum degree of fading, chalking or dulling
18、 and shall be completely free from evidence of cracking, checking, blistering or peeling. In addition, no cracking is allowed when the painted substrate is bent over a 50 mm mandrel at 23 +/- 2 C. Florida Direct Weathering 12 months at 5 (Miami area) facing south Accelerated Weathering 1000 h (FLTM
19、BO 101-01) Atlas XW weatherometer is required for initial paint qualification on typical approved production substrate.
