4、D FOR NEW DESIGN 1. SCOPE These specifications define the performance requirements for thick and medium film paints used on visible passenger car/commercial vehicle chassis components. WSK-M2P153-A1 For parts requiring minimal corrosion resistance or functional requirements. WSK-M2P153-A2 For parts

5、requiring extra-light corrosion resistance or functional requirements. WSK-M2P153-A3 For parts requiring light-moderate corrosion resistance or functional requirements. WSK-M2P153-A4 For parts requiring moderate corrosion resistance or functional requirements. WSK-M2P153-A5 For parts requiring sever

6、e corrosion resistance or long-time functional requirements. WSK-M2P153-A6 For parts requiring extra-severe corrosion resistance or extra long-time functional requirements. 2. APPLICATION These specifications were released originally to be specified where uniform coverage, good corrosion protection

7、and adequate appearance are necessary. ENGINEERING MATERIAL SPECIFICATION WSK-M2P153-A1/A6 Printed copies are uncontrolled Copyright 2008, Ford Global Technologies, Inc. Page 2 of 3 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDAR

8、D REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.3 SYSTEM COMPONENTS 3.3.1 Substrate As specified on the Engineering Drawing. 3.3.2 Cleaning The surface to be coated must be f

9、ree from oil or alkaline residues, fingerprints, rust, dirt, moisture, and other foreign materials. 3.3.3 Coating Material 3.3.3.1 The quality required is that obtainable with best commercial practice to meet the performance requirements of this specification. Either air dried or stoved finishes are

10、 permitted, and while a crystalline phosphate coating is not mandatory, it is recommended to phosphate coat for adequate adhesion and corrosion resistance. Light weight amorphous iron phosphate is not permitted. Any suitable method of coating application may be used. 3.3.3.2 Coating System Coating m

11、ust be sufficient to meet all performance requirements of this specification. Durability is obtained by a) Quality of materials used. b) Variation in film thickness. 3.4 FILM PROPERTIES 3.4.1 Color (FLTM BI 109-01) Black or dark gray or as specified on Engineering Drawing. 3.4.2 Gloss (FLTM BI 110-0

12、1). As specified on Engineering Drawing. ENGINEERING MATERIAL SPECIFICATION WSK-M2P153-A1/A6 Printed copies are uncontrolled Copyright 2008, Ford Global Technologies, Inc. Page 3 of 3 3.4.3 Initial Hardness The finish shall be sufficiently cured at the time of packing to withstand normal handling an

13、d shipping without damage. The finish shall produce a smooth hard film, free from sagging, dirt, and seed. 3.4.4 Film Thickness (FLTM BI 117-01) Film thickness must be sufficient to meet all the performance requirements of this specification. Parts shall be free from excessive runs, tears or other l

14、ocally heavy build-up which could lead to assembly problems. Production systems painting parts under this specification may be tested periodically by running control panels through the complete system, including metal cleaning, and shall be checked against the thickness recorded when the original pr

15、oduction approval was granted. Control panels shall be flat mild steel of convenient size polished on the significant face to 0.5 micrometre Arithmetic Average finish. 3.5 RESISTANCE PROPERTIES 3.5.1 Paint Adhesion Grade 0 (FLTM BI 106-01, Method B) No chipping 3.5.2 Salt Spray Resistance, min (FLTM

Note: Blistering, corrosion creepage

17、 or loss of adhesion in areas 6 mm or less from upper edges, holes, embossments, lap joints, welds or seam extensions of dipped or flow coated parts shall not be considered as failure. 3.5.3 Hot Oil Resistance The finish shall not blister, lift or show more than a slight softening or dulling after immersion for 1 h at 65 +/- 2 C in currently used factory-fill crankcase oil. 3.5.4 Special Requirements Threads are to be free from paint unless otherwise specified. Critical areas are to be masked as identified on the component drawing.
