    10、ll level with a min of orange peel. The surface of the material under test shall be equal to or better than current approved production material or smoothness when applied and baked under identical conditions. 3.5.3 Holdout There shall be no evidence of dulling or strike-in when enamel color coat is

    11、 applied over unsanded primer. 3.6 FILM PROPERTIES 3.6.1 Adhesion (FLTM BI 106-01) Both primer adhesion to substrate and enamel adhesion to primer shall be satisfactory, with no chipping. 3.7 RESISTANCE PROPERTIES Test panels or parts shall be prepared per paragraph 3.4 and tested with color coat en

    12、amel. Note: Aging of test panels or parts is not mandatory before testing for resistance properties. ENGINEERING MATERIAL SPECIFICATION ESB-M6J128-A2 Copyright 2012, Ford Global Technologies, LLC Page 3 of 5 3.7.1 Water Resistance, min 240 h (FLTM BI 104-01) Test Method: Immerse the part for 240 h i

    13、n distilled or deionized water maintained at 32 +/- 1 C. Remove parts from the water and immediately scribe an X through the finish to the substrate. Dry the scribed area with a paper towel, cloth, or air (oil and moisture free) and immediately apply, with firm thumb pressure, a min of 2 sq in (13 c

    14、m2) of ESF-M3G48 tape. Remove the tape by pulling one end at a 90 angle at moderate speed. The following conditions shall be basis for rejection: Removal of paint beyond 1/16 in (1.6 mm) from any scribe line. Any evidence of blistering or dulling of the paint at the scribe line or elsewhere on the p

    15、art. 3.7.2 Weathering Resistance (FLTM BO 101-01) The finish shall show a min degree of fading, chalking, or dulling, and no cracking when the part is bent over a 2 in (51 mm) mandrel. The flex test is performed at 23 +/- 2 C. No increase of brittleness nor loss of adhesion is permitted, and the fin

Note: Slight circular scratches in the direction of motion are not considered evidence of failure. 3.7.7 Heat Resistance There shall be no ev

    23、idence of cracking, checking, color change, or loss of adhesion after exposure to a time and temperature cycle equal to that required for the original processing of the part. 3.7.8 Chip Resistance (SAE J 400) There shall be no chipping when a finish part is subjected to 10 cycles. 3.7.9 Cold Flexibi

    24、lity (FLTM BN 102-01) Cracking of the paint is permitted provided no loss of adhesion of the paint develops at the cracks. Visible 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 is permitt

    25、ed. Test Method: Condition the sample for 4 h min at -29 C. Bend other samples over a temperature conditioned 1/2 in (13 mm) mandrel at -29 C. The operator should wear temperature conditioned gloves when performing the test. ENGINEERING MATERIAL SPECIFICATION ESB-M6J128-A2 Copyright 2012, Ford Globa
