2、ROCKER ARM COVER ESE-M2J60-B 1. SCOPE The material defined by this specification is a synthetic pigmented gloss baking enamel. 2. APPLICATION This specification was released originally for enamel used on engine valve rocker covers where gasoline, oil, water, salt spray and humidity resistance is req
3、uired. It is available in either a spraying grade or a dipping grade. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 COMPOSITION 3.2.1 Vehicle T
4、he fixed vehicle shall be an oil modified polybasic acid, polyhydric alcohol resin suitably modified with melamine and/or urea resins to meet the resistance requirements. The proportions of the hydrocarbons are to be so arranged that the enamel will level satisfactorily on spray applications. 3.2.2
5、The pigment shall be balanced and blended so that the finished enamel matches the Ford Motor Company master panel in color and luster and meets the requirements of this specification for durability. 3.2.3 Toxicity The enamels shall not contain any benzol (benzene), chlorinated or other toxic compoun
6、ds, or hydrolysable chlorine derivatives, or have an obnoxious or objectionable odor. 3.3 PHYSICAL PROPERTIES 3.3.1 Viscosity 26 - 40 s (FLTM BI 111-01) ENGINEERING MATERIAL SPECIFICATION ESE-M2J60-B Printed copies are uncontrolled Copyright 2008, Ford Global Technologies, LLC Page 2 of 4 3.3.2 Hidi
