31、, signed test report documenting testing to this specification prepared per TMS-9543. 5.2 Test Samples Test coupons or photographs showing failure modes for each test. 5.3 Test Procedure The complete test procedure including the procedures used for preparing and curing materials for test, including
32、surface preparation and condition of the test coupons. 5.4 Adhesives A description of the adhesive, substrate(s), and any chemicals/primers used for bonding, will be included in the report. 5.5 E-Coat Test Matrix Each new material must be tested with current E-coat substrates using a nine-condition
33、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 390 F, and under-bake conditions of 15 minutes at 325 F. The matrix includes test conditions in which film
34、 thickness is varied at 0.6 mil, 0.9 mil, and 1.2 mil. Ten (10) 4“x12“ panels are tested at each condition. 5.6 Primerless to Top Coat - Full Substrate Test Matrix Each new material seeking primerless approval to top coat must be tested with current top coated substrates at nominal (30min 250F), und
35、er 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 without prior ageing of the top coat and within the nominal manufacturing cycle time. The test matrix is to inc
36、lude 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 include thermoset acrylic monocoats, catalyzed and uncatalyzed urethane monocoats, and re-paint base coat/clear
37、coat panels simulating two and three tone paint jobs. 5.7 Primerless to Top Coat - Screening Substrate Test Matrix In the event of material screening the Full Test Matrix may be truncated to include only the nominal bake, one pass, base coat/clear coat panels on all four colors as described in Secti
38、on 5.6, and omitting the accelerated weathering and cold crack tests. 5.8 Primerless to Top Coat - Manufacturing Validation Test Matrix Manufacturing validation shall consist of a 9 week panel audit at each plant. A total of four colors and four panels per color shall be tested per week per plant by
39、 quick knife adhesion at initial conditions and after 240hrs of humidity exposure. The panels shall be tested as quickly as possible upon receipt from the plant.
