2、ER, BLACK SYNTHETIC DIPPING ESB-M6J72-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a black, synthetic modified, alkyd primer. 2. APPLICATION This specification was released originally for material used as a primer for miscellaneous small parts. It is general

3、ly applied by dip or flow coat, but may be sprayed by use of suitable reducing thinners. 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 COMPOSIT

4、ION 3.2.1 Non-Volatile, min 49% (FLTM BI 102-01) 3.2.1.1 Pigment 6 - 7% of non-volatile, composed of carbon black. 3.2.1.2 Resin Shall be phenolic and/or amine aldehyde oil modified alkyd resin. 3.2.2 Volatile Shall be composed primarily of hydrocarbon solvents, with alcohols added when required for

5、 stability. 3.2.3 Toxicity The material shall be non-toxic and shall not cause skin rash or irritation (dermatitis) to exposed handlers in normal production operations.

6、3.1 Weight Per Volume, min 6.9 lb/gal (83 kg/l) (ASTM D 1475) 3.3.2 Viscosity 30 - 40 s (FLTM BI 111-01) 3.3.3 Stability The material shall not jell or liver on standing or increase in viscosity more than 10 s after being aerated for 150 h. 3.3.3.1 Test Method for Storage Stability Place a sealed, 3

7、/4 full pt (0.5 l) can in an oven for 16 h at 60 +/- 1 C. An appreciable increase in viscosity (approximately 15 s) after thorough agitation, indicates non-stability. 3.3.3.2 Test Method for Resistance to Aeration (FLTM BI 016-01) 3.4 TEST PANEL PREPARATION Apply primer to zinc phosphate coated pane

8、ls as follows: 3.4.1 Dip Application (FLTM BI 103-02, Method “D“) Dry film thickness 0.0003 in (8 m) min at a point 2 in (51 mm) from upper edge of panel, 0.0005 in (13 m) min in lower half of panel. 3.4.2 Spray Application (FLTM BI 103-02, Method “E“) Dry film thickness 0.0005 - 0.0010 in (13 - 25

9、m). 3.4.3 Reduce to 15 - 20 s viscosity with M-14J220 for dip or spray. Bake 15 min at 177 C. 3.4.4 Color Coat For water immersion, salt spray and hold-out tests, spray 0.0015 in (38 m) ESB-M30J100 Quality Black Enamel over unsanded primer. Bake 17 min at 129 C. 3.5 APPEARANCE 3.5.1 Color Black 3.5.

10、2 Gloss, min 25 (FLTM BI 110-01) 3.5.3 Hold-out There shall be no evidence of dulling or strike-in when color enamel is applied over the primer.

11、) No chipping or flaking at primer to metal or enamel to primer interfaces. 3.7 RESISTANCE PROPERTIES 3.7.1 Water Immersion, min 240 h (FLTM BI 104-01) 3.7.2 Salt Spray Resistance, min 240 h (FLTM BI 103-01) 4. GENERAL INFORMATION The information given below is provided for clarification and assista

12、nce in meeting the requirements of this specification. 4.1 PRODUCTION BAKING CYCLES The following optional baking cycles are generally used for this material: 4.1.1 Gas Heated Oven With Forced Air Circulation Max ambient air temperature 204 C. Max metal temperature 190 C. A minimum of 5 minutes abov

13、e 163 C metal temperature on exterior surfaces. A minimum of 5 minutes above 121 C metal temperature on interior surfaces. Total time in oven is not critical, providing these requirements are met, but experience indicates that 14 20 min is generally sufficient. 4.1.2 New Gas Heated Oven with Increas

14、ed Forced Air Circulation 10 minutes minimum in an oven giving 204 C peak metal temperature, including 5 minutes minimum at 177 C metal temperature. Air velocity parallel to and 2 in (50 mm) from body surface at 250 ft/min (76 m/min) average determined by a Hastings Probe Velocimeter. 4.1.3 Infra-Red Lamps, min 15 minutes Metal temperature of 149 - 176 C.
