GENERAL INFORMATION This infor

23、mation given below is provided for clarification and assistance in meeting the requirements of this specification. Contact for questions concerning Engineering Material Specifications. 4.1 RE-WORK Wheels to be processed through coating operations a maximum of 2 times (initial and one re-work). Subs

24、equent rework after 2 coatings requires that the wheels be stripped prior to coating. Re-worked wheels must match the master samples originally approved by the Design Center and meet all of the specification performance requirements. 4.2 STRIPPING Wheel stripping processes must not degrade the mecha

25、nical properties of the wheel. Recommended processes are listed below: Kolene Corporation - Kolene Recover 5000 Process 12890 Westwood Avenue, Detroit, MI 48223 (313) 273-9220 or Henkel Corporation P3 Stripper 3000 32100 Stephenson Highway, Madison Heights, MI 48071 (248) 583-9300 or 4.3 RECOMMEND

26、ED TESTING REQUIREMENTS FOR DESIGN VALIDATION, PRODUCTION VALIDATION, AND SREA. Paint performance is a function of material selection, surface preparation, and paint application. For established coatings and coating lines, this may permit a reduced test schedule to validate compliance to this specif
