2、ATALYST, ACCELERATOR - ELASTOMERIC REPAIR ENAMELS ESB-M99J299-A (DIBUTYL TIN DILAURATE) NOT TO BE USED FOR NEW DESIGN 1. SCOPE The materials defined by this specification are catalyst solutions for ESB-M2J121 Elastomeric Enamels. 2. APPLICATION This specification was released originally for catalyst
3、s used to convert standard high bake ESB-M2J121 Elastomeric Enamels to low bake enamels for repairing elastomeric fascia on passenger vehicles in the assembly plants. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys
4、 Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 SPECIFIC GRAVITY, 15.56/15.56 C 0.676 - 1.076 (ASTM D 891) 3.3 FLASH POINT, C 1.7 C (ASTM D 93) 3.4 COMPOSITION, WT% Aromatic hydrocarbon(s) 98.0 Dibutyl tin dilaurate 2.0 3.5 PERFORMANCE Appearance, gloss, hardness, flexibility a
5、nd intercoat adhesion of a catalyzed enamel applied over a high bake uncatalyzed enamel shall be satisfactory. 3.5.1 Panel Preparation, Initial Qualification Determine performance of catalyst in ESB-M2J121 Elastomeric Enamels using 1 solid and 1 metallic color (ZWFAXXA White and SPLCXXA Silver Metal
6、lic preferred). Prepare 2 panels per color of uncatalyzed enamel per para 3.3 of the appropriate elastomeric enamel specification. On the right half of one test panel per color, sand through the enamel exposing an approximately 3 cm2 circular area of the primer film. Reduce the appropriate catalyzed
7、 enamel to spray viscosity. Apply 31 - 38 m (dry film thickness) of catalyzed enamel to the right one-half of the panel, lengthwise, so that the catalyzed enamel is applied over sanded and unsanded portions of the high bake enamel. Bake panels under IR lamps to obtain a minimum surface temperature o
8、f 72 C for 10 minutes. ENGINEERING MATERIAL SPECIFICATION ESB-M99J299-A Copyright 2012, Ford Global Technologies, LLC Page 2 of 2 3.6 FILM PROPERTIES Catalyzed and high bake films shall meet the following requirements: 3.6.1 Initial Hardness, 23 +/- 2 C The catalyzed film shall be sufficiently hard
9、to withstand normal handling. 3.6.2 Appearance The color and gloss shall match to provide a uniform visible appearance. 3.6.3 Flexibility, 23 +/- 2 C No cracking when bent over a 1 in (25 mm) mandrel. 3.6.4 Intercoat Adhesion (FLTM BI 106-02) No pull away at the scribed line when taped. 5. GENERAL I
10、NFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 FLAMMABILITY AND/OR TOXICITY This material represents a potential fire and/or health hazard. The Manufacturing Engineering Department shall notify both the Plant Security and the Safety Units of its presence in the Plant to assure that proper fire and/or health precautions are provided. The location in which it is used or stored shall be included in the notifications.
