10、 free in 5 min 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 objectionable distortion of the body enamel. 3.5 PRE
11、PARATION 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 min at 129 C, cool and rebake 17 min at 129 C. Wipe the panels with M14J147 Naphtha or equivalent. Remove any residue by wiping with a cl
12、ean 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, except adhesion test panels, must be allowed to cure o
13、ne 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 single edged razor blade, cut through the striping enamel s
14、tripes 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 quickly. No enamel shall adhere to the tape. 3.7 RESISTANCE
15、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. 3.7.2 Gasoline Resistance The material, when applied per para 3.5, shall not blister or show any evidence of loss
16、of adhesion and shall exhibit no more softening, dulling, color transfer or color change after a 24 h recovery period than the sample originally submitted and approved by Paint and Materials Engineering.

17、ies, Inc. 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 for evidence of color transfer, and the striping enamel for evidence of degradation. 3.7.3 Weatherin
18、g 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: 3.7.3.1 Florida Exposure (Miami area) 12 months at 5 deg facing South. 3.7.3.2 Accelerated Weather
19、ing 400 h (ASTM G-53, QUV (or equivalent) with a cycle of 4 h UV exposure at 60 C and 4 h condensing humidity at 50 C using FS40 bulbs.) 3.7.4 Thermal Shock (FLTM BI 107-05) The striping enamel when applied in accordance with para 3.5, Type I, shall show no blistering or loss of adhesion when subjected to the following cycling test. 4 h water immersion 4 h minimum exposure at - 29 C 4 h direct steam blast at 45 deg angle, 50 - 75 mm from panel for 15 s minimum. 5.
