2、, Ford Global Technologies, Inc. MOLDED COATING FOR COMPRESSION ESB-M99J331-A MOLDED FRP - ONE COMPONENT NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a thermosetting modified acrylic compound applied to compression molded fiberglass reinforced polyester (FRP)
3、parts during the molding operation. This material is designed to fill porosity, voids, and provide good adhesion and enamel holdout properties when applied to FRP. 2. APPLICATION This specification was released originally for material used as a molded-in primer surfacer on high visibility exterior F
4、RP parts such as hoods, grille opening panels and other body panels. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to the Companys Quality System Requiremen
5、ts. 3.2 PHYSICAL PROPERTIES 3.2.1 Solids, min 65% (FLTM BI 2-1) 3.2.2 Weight per Volume 1.26 +/- .02 kg/L (FLTM BI 2-2) 3.2.3 Viscosity 6 000 - 17 000 (ASTM D 1824, #7 Spindle at centipoises 100 RPM and 30 C) 3.2.4 Gel Time 4 - 20 min (TBD, based on 0.75 to 138 C Peak 1.5 parts per 100 catalyst) Exo

Each FRP formulation must be approved separately for use with these materials. 3.3.2 Mold
7、 Shall be representative of production tooling. Testing of samples from production level tooling is required before final approval to these specifications. 3.3.3 Molded Coating Components ESB-M99J331-A and tertiary butyl perbenzoate (TBPB) 98% pure min, are to be applied in the ratio recommended by
8、the manufacturer to the test specimen by means of an automatic injection system or hand pour (laboratory test panels only). Minimum dry film thickness per FLTM BI 17-1, using the Mark II, Tooke Gage shall be 13 m. Each fabricator must be approved separately to use these materials. 3.3.4 Electrocoat
9、Test specimens shall be prepared both with and without an exposure to a simulated electrocoat bake of 30 min at 205 C ambient on the molded coating. 3.3.5 Primer(s) Apply the current approved production primer(s) at 13 m minimum dry film thickness in accordance with the pertinent engineering materia
10、l specification at both the minimum and the maximum bakes (see para 5). 3.3.6 Topcoat Apply the current approved body production exterior enamel used in the assembly plants in accordance with the pertinent engineering material specification (see para 5). Use white enamel for the following: Adhesion
11、(para 3.5.1). Chip resistance (para 3.6.1). Use black enamel for all other tests requiring topcoated samples. ENGINEERING MATERIAL SPECIFICATION ESB-M99J331-A Page 3 of 6 Copyright 2012, Ford Global Technologies, Inc. 3.4 APPEARANCE 3.4.1 Color Black 3.4.2 Leveling The molded coating as applied per
12、para 3.3.3 shall provide a smooth uniform appearance free from pits, cracks, bubbles, etc. 3.4.3 Gloss 40 min (As Processed on a (FLTM BI 10-1, 60 Polished Chrome Tool) Glossmeter as applied per para 3.3.3) 3.4.4 Distinctness of Image 90 min (FLTM BI 10-3, prepare test specimen per para 3.3 using bl
13、ack high gloss exterior enamel) When it is not feasible to obtain a distinctness of image reading due to the contour and/or size of the part, evidence of dulling or strike-in of the topcoat shall be cause for rejection. 3.5 FILM PROPERTIES 3.5.1 Adhesion Part “A“ No flaking or chipping. (FLTM BI 6-1
14、 Part “B“ Both molded coating adhesion on samples prepared per para 3.3) to substrate and guidecoat adhesion to molded coating shall be no worse than grade 3, figure 1. 3.5.2 Hardness F - 2H (ASTM D 3363, samples prepared per para 3.3.1-3.3.3. Use Eagle Turquoise T 2375 pencils) 3.5.3 Electrical Con
15、ductivity (Type I), min 125 (Ransburg Electro-Coating Corp., Model 236 Sprayability Meter or Equivalent) 3.5.4 Dry Sanding Characteristics The molded coating when applied as outlined in para 3.3.3, shall dry sand (using a new sheet of 280 grit stearate filled paper for each panel) smoothly without c
16、logging the paper and with a minimum of sand scratches. The material shall be equivalent in all respects to current approved production molded coating applied and tested under identical conditions.
