2、, SOLID FILM - MEDIUM ESA-M99C38-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a type of solid film lubricant described as molybdenum disulfide bonded to a phosphate treated metal surface by a thermosetting resin, plus additions of other dry lubricants such a

3、s graphite. It is intended for the coating of metallic parts to materially lower the coefficient of friction and minimize adhesion of parts operating dry. It is also intended to produce a coating on mild steel parts which have corrosion resistance in addition to lubricity. 2. APPLICATION This specif

4、ication was released originally for lubricant used to coat brake adjusting screws, sockets, and nuts. 3. REQUIREMENTS (When applied to phosphate treated surfaces.) 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requireme

5、nts For Production Materials (WSS-M99P1111-A). 3.1 FILM CHARACTERISTICS This material shall form a continuous, homogeneous coating of uniform thickness, free of cracks, blisters and foreign material. 3.2 APPLICATION CHARACTERISTICS This material shall be suitable for application by spraying or dippi

6、ng at room temperature. 3.3 TOXICITY The coating shall not contain chlorinated solvents or other compounds of known high toxicity under normal conditions of usage. 3.4 COLOR Dull charcoal gray to black 3.5 FILM THICKNESS, min 0.0001 in (0.003 mm) 3.6 DRYING TIME 15 min, non-tacky ENGINEERING MATERIA
