28、s submitted for approval to this specification shall include a detailed, signed test report per MPAPS P 9543, test coupons or photographs showing failure modes for each test, the complete test procedure, and a description of the adhesive, substrate(s), and any chemicals/primers used for bonding. 5.1

29、 E-Coat Test Matrix Each new material must be tested with current E-coat substrates using a nine-condition test matrix. The matrix evaluates the adhesion of the urethane to E-coated panels that have been exposed to nominal oven conditions of 30 minutes at 350 F, over-bake conditions of 60 minutes at

30、 390 F, and under-bake conditions of 15 minutes at 325 F. The matrix includes test conditions in which film thickness is varied at 0.6 mil, 0.9 mil, and 1.2 mil. Ten (10) 4“x12“ panels are tested at each condition. 5.2 Primerless to Top Coat - Full Substrate Test Matrix Each new material seeking pri

31、merless approval to top coat must be tested with current top coated substrates at nominal (30min 250F), under bake (20min 200F), and over bake conditions (40min 260F). Paint film build shall be nominal as recommended by the paint manufacturer. The adhesive shall be applied to the fresh top coat with

32、out prior ageing of the top coat and within the nominal manufacturing cycle time. The test matrix is to include the current base coat/clear coat system at catalyzed and uncatalyzed clear coat conditions in the following colors: NAV0001, NAV9219, NAV2503, and NAV4587. The test matrix is also to inclu

33、de thermoset acrylic monocoats, catalyzed and uncatalyzed urethane monocoats, and re-paint base coat/clear coat panels simulating two and three tone paint jobs. 5.3 Primerless to Top Coat - Screening Substrate Test Matrix In the event of material screening the Full Test Matrix may be truncated to in

34、clude only the nominal bake, one pass, base coat/clear coat panels on all four colors as described in Section 5.6, and omitting the accelerated weathering and cold crack tests. 5.4 Primerless to Top Coat - Manufacturing Validation Test Matrix Manufacturing validation shall consist of a 9 week panel

35、audit at each plant. A total of four colors and four panels per color shall be tested per week per plant by quick knife adhesion at initial conditions and after 240hrs of humidity exposure.
