2、 PLASTIC - INTERIOR- AIR DRY ESB-M6J121-A OR BAKING COLOR COAT NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a primer with good adhesion to polypropylene surfaces. The primer may be either clear or pigmented. 2. APPLICATION This specification was released origi

3、nally for primers used as thin flash coats on interior polypropylene parts, followed by primer surfacer and/or color coats. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Mater

4、ials (WSS-M99P1111-A). 3.2 COMPOSITION The non-volatile portion shall be composed of resins with good adhesion to polypropylene, and may be pigmented as a guide to visual coverage if desirable. The volatile portion shall be balanced to provide good application properties and complete surface wetting

5、. The material shall be compatible as a flash primer with enamels or primer surfacers normally used in production. The material shall be non-toxic and shall not cause skin rash, or irritation (dermatitis) to exposed handlers in normal production operations. 3.3 PHYSICAL PROPERTIES 3.3.1 Non-Volatile

6、 Solids (FLTM BI 102-01) Shall be established by the vendor on the initial approved production batch. Tolerance shall be +/- 2.0%. 3.3.2 Viscosity (FLTM BI 111-01) Shall be established by the vendor on the initial approved production batch. Tolerance shall be +/- 5 s. ENGINEERING MATERIAL SPECIFICAT

7、ION Copyright 2012, Ford Global Technologies, LLC Page 2 of 3 3.3.3 Stability The material shall not liver or jell and shall retain its normal application and working properties after 30 days shelf storage at 23 +/- 2 C. 3.4 PREPARATION OF TEST PANELS (FLTM BI 103-02, Method “A“, with exceptions as

8、noted below) 3.4.1 Substrate Conduct tests on both high impact grade polypropylene and filled polypropylene. 3.4.2 Surface Preparation Wipe plastic with M14J148 Petroleum Naphtha. 3.4.3 Primer Spray as received, without reduction, 1-2 passes completely wetting the panel (film thickness 0.1 mil (2.5

9、m) max). 3.4.4 Color Coat Apply 1.0 mil (26 m) min as follows: ESB-M99J264-A, Air Dry, for both natural (unfilled) and filled polypropylene plastic. ESB-M99J265-A, Baking for filled polypropylene plastic. (Bake 17 min at 129 C) 3.4.5 Aging All panels shall be aged 24 h min at 23 +/- 2 C before testi

10、ng. 3.5 APPEARANCE When properly applied per paragraph 3.3, the system shall dry to a presentable, serviceable film showing no craters, pinholes, seediness or abnormal roughness. There shall be no evidence of dulling or enamel strike in to the primer. 3.6 ADHESION No chipping or (FLTM BI 106-01) fla

11、king 3.7 RESISTANCE PROPERTIES 3.7.1 Water Resistance, min 24 h Test Method: Immerse the panels in distilled or deionized water maintained at 32 +/- 1 C per FLTM BI 104-01. Remove from water and immediately scribe an X through the material to the substrate. Dry the scribed area with a paper towel, c

12、loth or air pressure and immediately apply, with firm thumb pressure, a min of 2 sq in (13 cm2) of ESF-M3G48 tape. Remove the tape by pulling one end at a 90 angle at a moderate speed. The following conditions shall be basis for rejection: ENGINEERING MATERIAL SPECIFICATION Copyright 2012, Ford Glob

13、al Technologies, LLC Page 3 of 3 Removal of paint beyond 1/16 in (1.6 mm) from any scribe line. Any evidence of blistering after tape removal. 3.7.2 Weathering Resistance Panels prepared in accordance with paragraph 3.3 shall show no increase of brittleness nor loss of adhesion and panels shall be c

14、ompletely free from evidence of cracking, checking, blistering, or peeling when exposed as follows: Florida Exposure (Miami area) 6 months min at 45 under glass facing south. Accelerated Weathering (FLTM BO 101-01) 200 h in Atlas Weatherometer. 3.7.3 Water Resistance After Weathering After panels ha

15、ve been subjected to either Florida or Weatherometer exposure as specified in paragraph 3.6.2, they shall be tested for 24 h water resistance as described in paragraph 3.6.2. Peeling of the paint film in excess of 1/8 in (3 mm) from the scribe mark shall be cause for rejection. Examine for blisterin

16、g. Blistering in rinse pattern obviously due to panel preparation shall not be cause for rejection provided adhesion is satisfactory. General blistering is considered failure. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements

17、of this specification. 4.1 FLASH POINT Below 26 C 4.2 FLAMMABILITY This material represents a potential fire 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 precautions are provided. The location in which it is used or stored shall be included in the notifications.
