All test specimens shall be injection molded plaques or parts having a nominal thickness of 2.5 +/- 0.2 mm or as specified on the engineering document. 3.3.3 Plastic

11、 Preparation The surface to be painted shall be cleaned by an acceptable process, e.g. power wash, to remove mold releasing agents, fingerprints, oils, dirt and moisture. 3.3.4 Primer When necessary in order to meet the requirements of this specification, an adhesion primer, primer surfacer or seale

12、r may be needed. Surface enhancements, such as flaming or plasma treatment that modify surface tension, surface resistivity may also be required in order to meet the requirements. This must be noted in the initial submission package and recorded on the Ford Approved Source List (ASL). 3.3.5 Cure Sup

13、plier shall define Cure Window as described in Paragraph 3.6. This should be included in the submission package and DFMEA. ENGINEERING MATERIAL SPECIFICATION WSS-M15J17-A2 Copyright 2013, Ford Global Technologies, LLC Page 3 of 5 3.3.6 Aging Test panels or test specimens prepared for investigations

14、according to this specification must be aged for at least 72 hours at 23 +/- 2 C or 16 hours at 45 +/- 1 C prior to testing. 3.4 APPEARANCE 3.4.1 General Color, gloss, grain, tactile effect and surface finish shall match master Trim Sample and/or Master Appearance Sample as approved by Corporate Des

15、ign The coating shall exhibit no craters, pinholes, solvent popping, seediness, abnormal roughness, or excessive flow. 3.4.2 Color (FLTM BI 109-01, Visual Assessment) (SAE J1545, MA58 Three-Angle CMC) Shall match the Master Approved Sample. 3.4.3 Gloss (FLTM BI 110-01, ASTM D 523) As released by Eng
