10、4.6 Dry Time: The enamel shall air dry dust free in 5 minutes and hard in 16 h. Individual plant conditions may require supplemental heating to achieve faster tack-free conditions. 3.4.7 Repairability: The applied stripe must be removable within 48 h with xylol to permit inplant repair without obje
11、ctionable distortion of the body enamel. 3.5 PREPARATION OF TEST PANELS (FLTM BI 103-02, Method C) Prepare 100 x 300 mm steel test panels using all current qualities of production enamel color coats and bake 17 minutes at 129 C, cool and rebake 17 minutes at 129 C. Wipe the panels with M14J147 Napht
12、ha or equivalent. Remove any residue by wiping with a clean dry cloth. Type I - To one panel, apply three vertical stripes of the striping enamel with a striping tool representative of that used in production. Type II - To a second panel, spray a full covering coat of the striping enamel. All panels
13、 except adhesion test panels, must be allowed to cure one week at room temperature prior to testing. 3.6 FILM PROPERTIES 3.6.1 Adhesion After 24 h air dry at 23 +/- 2 C, the striping enamel shall show satisfactory adhesion to all current production qualities of body enamel. Test Method: Using a sin
14、gle edged razor blade, cut through the striping enamel stripes only. Apply a strip of 3M #898 tape, 25 mm wide, to the Type I panel, prepared per para 3.5, over the razor blade cut and at right angles to the painted stripes. Press down moderately, using thumb pressure only, and then pull upward quic
15、kly. No enamel shall adhere to the tape. Repeat after 72 h air dry at 23 +/- 2 C. 3.7 RESISTANCE PROPERTIES 3.7.1 Water Immersion, min 240 h The striping enamel, when applied in accordance with para 3.5, shall show no blistering or loss of adhesion, and no more than slight dulling.

16、IAL SPECIFICATION WSB-M1J210-A Page 4 of 4 Copyright 2012, Ford Global Technologies, Inc. 3.7.2 Gasoline Resistance The material, when applied per para 3.5, shall not blister or show any evidence of loss of adhesion and shall exhibit no more softening, dulling, color transfer or color change after a
17、 24 h recovery period than the sample originally submitted and approved by Paint and Materials Engineering. Test Method: Place the painted panel in a 600 mL beaker half full of M14J148 Petroleum Naphtha - Aliphatic Type for 1 h at 23 +/- 2 C. Wipe the panel with a soft cloth and examine the cloth fo
18、r evidence of color transfer, and the striping enamel for evidence of degradation. 3.7.3 Weathering The striping enamel, when applied in accordance with para 3.5, shall show no cracking, checking, blistering or peeling, and no more than slight color change or loss of gloss, when exposed as follows:
19、3.7.3.1 Florida Exposure (Miami area) (SAE J1976, Procedure “A“) 12 months at 5 deg facing South. 3.7.3.2 Accelerated Weathering 1000 h (SAE J1960) 3.7.4 Thermal Shock (FLTM BI 107-03) The striping enamel when applied in accordance with para 3.5, Type I, shall show no blistering or loss of adhesion
20、when subjected to the following cycling test. . 4 h water immersion . 4 h minimum exposure at - 29 C . Direct steam blast at 45 deg angle, 50 - 75 mm from panel for 15 s minimum. 5.
