Dry the scrib

16、ed area with a paper towel, cloth or air pressure and immediately apply, with firm thumb pressure, a min of 13 cm of ESF-M3G48 tape. Remove the tape by pulling one end at a 90 angle at a moderate speed. The following conditions shall be basis for rejection: . Removal of paint beyond 1.6 mm from any

17、scribe line. . Any evidence of blistering or dulling of the paint at either the scribe or any other area of the panel. 3.6.2 Weathering Resistance Panels prepared in accordance with paragraph 3.3 shall show a min degree of fading, chalking, or dulling. No cracking when bent over a 51 mm mandrel on 6

18、.4 mm thick elastomeric substrate. No increase of brittleness or loss of adhesion is permitted and panels shall be completely free from evidence of cracking, checking, blistering, or peeling when exposed as follows: . Florida Exposure (Miami area) 12 months at 5 facing south . Accelerated Weathering

19、 1600 h (FLTM BO 101-01) Required for initial paint qualification on typical approved production substrate. 3.6.3 Thermal Shock Resistance (FLTM BI 107-05) The enamel shall exhibit no blistering or loss of adhesion when subjected to the following cycle. . 4 h water immersion . 4 h min exposure at -2

24、ence of loss of adhesion. Test Method: Place the painted panel in Rotunda Motor Oil (SAE 10W30). After 1 h at 21 C min, remove the panel and wipe the painted surface with a soft cloth and examine the cloth for evidence of color transfer and the paint film for evidence of degradation. 3.6.8 Heat Resi

25、stance There shall be no evidence of cracking, checking, or color change after exposure in a mechanical convection oven for 30 min at 88 +/- 2 C. 3.6.9 Cold Flexibility (FLTM BN 102-01) Cracking of the paint coating is permitted provided no loss of adhesion of the paint develops at the cracks. Visib

26、le hairline paint cracks are acceptable when the test piece is restored to its normal plane. Cracks in the elastomeric substrate, up to 10% of the part thickness are permitted.
