11、n Of Paint/Primers 4.1.1 Material/Process Approvals The primers used by the supplier must be approved by Materials Engineering to meet the dry film requirements of MPAPS G-5 and/or MPAPS G-9009, prior to their first use in production. In addition, parts primed with the materials and applications pro
12、cesses/methods to be used by the supplier shall be approved by Materials Engineering and, after approval, no deviation in materials and/or manufacturing processes are permitted without approval by Materials Engineering. 4.2 Qualification Of Paint 4.2.1 Material The initial qualification tests of pai
13、nt shall be performed on parts molded from the same material and by the same molding process in which the finished parts are specified. These panels shall be coated with the paint to be tested using the procedure listed below. In cases where a primer is specified in addition to the topcoat, the pane
14、ls shall contain both coatings applied by the intended production process. These panels shall be submitted to Materials Engineering for approval with the vendors test results. Final qualification shall be performed on the finished part prior to production release. 4.2.2 Sample Preparation 4.2.2.1 A
15、minimum two (2) parts shall be submitted for qualification for each test. 4.2.2.2 Prior to painting, the samples shall be cleaned with solvents or cleaners as necessary. This operation shall simulate production procedure. 4.2.2.3 The paint/primer shall be applied to a minimum dry film thickness to p
16、rovide black/grey hiding (Morass chart) per the manufacturers recommended process. 4.2.2.4 The painted samples shall be cured by means which simulate production procedures. Baking cycles shall not be detrimental to the base plastic. 4.3 Testing Finish painted parts, primed or unprimed, when topcoate

No suffix will be used when full gloss is required (83 minimum) or when specifying primers and casting sealers. Suffix letter
23、s and their respective gloss levels are as follows: Suffix 60 Gloss Suffix 60 Gloss Suffix 60 Gloss Suffix 60 Gloss Suffix 60 Gloss A 85 5 D 55 5 G 25 5 K 15 - 20 N 2 - 5 B 75 5 E 45 5 H 15 5 L 10 - 15 C 65 5 F 35 5 J 10 5 M 5 - 10 5.0 QUALITY Painted parts shall be adherent and uniform in color and
24、 texture, with no thin spots, runs, wrinkles, porosity, pits, blisters or nodules. 5.1 Porosity In instances where porosity is not detectable until after the primed substrate has been painted, isolated cases of porosity as defined in Table 1 shall not be cause for rejection. Porosity that is chronic
25、 and requires significant amounts of rework shall be cause for rejection and it is the responsibility of the supplier to correct this condition. The supplier has the responsibility to provide quality primed parts which will not cause delayed defects after finishing in the using plant. This condition
26、 will require close cooperation with the paint facility and with Materials Engineering. 5.2 Appearance Requirements Specific appearance requirements are given in Table 1.
