4、 Notice: Revised Table 1 to include porosity; editorial changes. Reference: File 30-13A 1.0 APPLICATION This specification covers the prepaint treatment required for open or closed mold fiberglass reinforced thermosetting plastic parts, or thermoplastic parts that are injection molded or thermoforme
5、d, which are to be subsequently finish painted in NAVISTAR facilities. Typical parts are hood and fender assemblies, headlight panels, radiator grilles, window panel inserts, engine covers, and similar exterior and interior applications. 2.0 SCOPE This specification covers surface appearance and dry
6、 film property requirements of the primer, inspection, KCC, quality control and source approval, repair of primed surfaces, and handling required for prime painted FRP or thermoplastic parts prior to shipment to the using NAVISTAR plant. Parts receiving heat cured topcoats and parts that specify air

11、o specify the exact process and materials to be used in providing plastic parts ready for topcoating in NAVISTAR painting operations. The control of the primer quality and its application shall be the responsibility of the part supplier. All primed parts supplied shall be compatible with the finish
12、painting operations employed by the using NAVISTAR plant. 4.1 Material/Process Approvals The primers used by the supplier must be approved by NAVISTAR Materials Engineering to meet the dry film requirements of Grade -52 and/or Grade -52HS as per CEMS G-5, Part V, prior to their first use in producti
13、on. In addition, parts primed with the materials and application processes/methods to be used by the supplier shall be approved by Materials Engineering and, after approval, no deviation in materials and/or manufacturing processes shall be permitted without written approval by Materials Engineering.
14、 4.1.1 A typical preparation and priming procedure is shown in the General Information Section. This procedure has provided acceptable parts when used with good substrate and the proper materials. 4.2 In-Mold-Coating Priming of FRP parts which use in-mold-coating (IMC) as a sealer to seal the part r
15、equires special treatment. In cases where coverage of the part with IMC is essentially complete, if needed, the use of spot primer will be satisfactory. In cases where coverage of the part with IMC is less than complete, the use of a 1.0-2.0 mil dry film primer-sealer (with oven bake after applicati
16、on of the primer-sealer) will be required to seal the substrate. If the incompletely covered area is less than 2 inches in diameter, no priming may be necessary if the area does not show through the topcoat and does not promote surface defects (e.g., pitting and porosity). Spot priming (and rebake)
17、of these areas is acceptable if there is no show-through of primer boundaries after topcoat . If show-through occurs, the entire part must be primed and oven baked prior to topcoating. 4.3 Surface Quality It is recognized that certain defects, such as substrate porosity, may not be detectable in a p
18、rimed part until after topcoating. Isolated instances of porosity, as defined in Table 1, shall not be considered cause for rejection. Chronic cases of porosity requiring significant rework shall be cause for rejection and the responsibility of the vendor to correct. The supplier has the responsibil
19、ity to provide quality primed parts which will not cause delayed defects after finishing in the using plant. Parts supplied shall be free of dirt, oils, molding flash, sharp edges or other potential contaminants that could cause in-plant rework and negatively impact overall quality. This will requir
20、e close cooperation with the paint facility at the using plant and with Materials Engineering. 4.4 Appearance Requirements Specific appearance requirements are given in Table 1. Appearance requirements are specified for the following zones or locations on the vehicle: NUMBER: TMS-9005 TITLE: Prepain

22、I Primary, exterior, glamour surfaces, such as: hood and fender exteriors, including visible edges; grilles, cab fronts, sides, doors, corners, and lower aerodynamic fairings. II Secondary, exterior, glamour surfaces, such as: cab tops, cab backs (between corner radii) and upper aerodynamic fairings
23、. Also, primary, interior, low gloss painted surfaces, such as: engine covers and instrument panels. III Recessed exterior or interior surfaces, such as: door openings, door ends, and painted grab handles. IV Hidden areas, such as those covered in assembly and backsides, if primed. 4.4.1 Inspection
24、Conditions Parts shall be inspected for appearance requirements at a distance of 2 feet under a light intensity of 100 foot-candles minimum at the part surface. Samples illustrating acceptable appearance and unacceptable appearance defects shall be prepared and displayed in the inspection area. 4.5
