2、POWDERED, THERMOSETTING EPOXY ESF-M70J1-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines the performance requirements for a thermosetting epoxy powder applied by the electrostatic method to a metal part. 2. APPLICATION This specification was released originally for coating extreme

3、ly corrosive environments within the emission system. This coating does not possess the ultraviolet stability which would permit exterior decorative applications. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Sta

4、ndard Requirements For Production Materials (WSS-M99P1111-A). 3.1 TEST PANELS Chemically cleaned low carbon steel panels shall be electrostatically sprayed with epoxy powder and cured at 205 C for 5 min. 3.1.1 Hardness, Knoop 10 - 15 (ASTM D 1474, Method “A“) 3.1.2 Adhesion No flaking or chipping (F

Remove and quench in cold water. Dry and immerse in an alcohol-dry ice solution at -75 C for 10 min. Remove and insp

6、ect for signs of cracking, crazing, or loss of adhesion. Repeat above cycle 9 more times. At the end of the 10 cycles there must be no cracking, crazing, or signs of adhesion loss. 3.1.5 Thickness, min 0.001 in (30 m) (ASTM D 1186) ENGINEERING MATERIAL SPECIFICATION ESF-M70J1-A Copyright 2011, Ford

8、les, undercoating voids or mechanical damage. 3.2.2 Adhesion No flaking or chipping (FLTM BI 106-01) 3.2.3 Salt Spray, min 240 h (FLTM BI 103-01) 3.2.4 Thickness, min 0.001 in (30 m) (ASTM D 1186) 3.2.5 Cure There must be no softening of coating or evidence of color rubbing off when a cloth dipped i

9、n MEK or acetone is rubbed over the surface of the resin. 3.3 TOXICITY This material shall be considered as relatively non-toxic compared to liquid epoxies. However, since it is an epoxy, care should be taken to avoid prolonged exposure to the skin. This material should be used in a closed system to reduce the possibility of breathing the powder. 3.4 EXPLOSION HAZARD As stated, the material should be used in a closed system because of the possibility of dust explosion present in powdered material.
