SCOPE The material defined by this specification is a paint system for organic zinc rich base coat with a black thermoset sealer topcoat. The two coat paint system is applied by imme

3、rsion to L.C. steel. Prior to application of the paint system, the base steel is cleaned and pretreated with an iron phosphate immersion process. 2. APPLICATION This specification was released originally for use on L.C. steel fuel filler tubing requiring corrosion protection and fuel/alcohol resista

4、nce. The two coat paint immersion system is suitable for internal and external use in the fuel system. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A)

5、. 3.4 APPEARANCE (Actual production parts are to be used in testing unless otherwise specified) After each paint/cure exposure the part shall be uniform in appearance exhibiting no localized buildup on tube ends, free of blisters, bubbles, foreign material and similar imperfections. 3.5 COLOR Black

6、unless otherwise specified on Engineering drawing (FLTM BI 109-01) 3.6 CURE TEST No softening or color transfer Test Method: The finished paint film shall withstand a minimum of 50 double rubs using a 100% cotton cheesecloth saturated with MEK or acetone. 3.7 DRY FILM THICKNESS Total 20 - 30 m (FLTM

7、 BI 117-01 or an approved equivalent) 3.8 DRY FILM COMPOSITION, Base Coat 76 80% (Weight, metallic zinc content) 3.9 SALT SPRAY, min 336 h (ASTM B 117) The finished part shall have a rating of 6 or better per ASTM D 1654, Procedure A & B.

Page 2 of 2 3.10 CHIP RESISTANCE, min After completion of 336 h salt spray cycle there shall be no corrosion spreading beyond damaged or adjacent areas. Test Method: Section filler tube longitudinally and subject sample to 1 cycle of

9、gravelometer damage per SAE J400. Expose sample to salt spray. 3.11 ADHESION No chipping, flaking, or rust Test Method: “X“ scribe tubing with carbide tip tool through paint coatings to base steel. Place tube into salt spray for 336 h duration. No creepage permitted beyond scribe lines. 3.12 FUEL RE

10、SISTANCE No softening or peeling Test Method: The finished part shall withstand a minimum of 2000 h when tested in a soxhlet extractor at 89 +/- 1 C or when immersed at room temperature. The paint film shall not soften, peel or show any signs of defect when tested in any fuel/methanol alcohol blend

11、ratio containing 20 ppm formic acid, 2 ppm chloride ion and 1000 ppm distilled water. 3.13 SURFACE RESISTANCE, max 10E6 ohms (ASTM D 4496, ASTM D 257 tube specimen) Measurement of the finished coated product shall be tested to ensure adequate conductivity to discharge any static electricity that may be generated. 5. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 A hot alkaline cleaning system is suggested prior to immersion in an iron phosphate bath (ESF-M3P3-A).
