2、f 2 POLYVINYL CHLORIDE (PVC) COPOLYMER, HOT DIP ESB-M4D148-A PLASTISOL 1. SCOPE The material defined by this specification is a vinyl chloride copolymer base, hot plastisol dip. 2. APPLICATION This specification was released originally for material used as a hot dip coating over metal components suc
3、h as the glove compartment door check to reduce metallic noise and can be used as a decorative coating as well. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M9
4、9P1111-A). 3.2 COLOR As specified on engineering drawings 3.3 SOLIDS CONTENT, min 98% (ASTM D 2834, except heat at 102 +/- 3C for 3 h in a mechanical convection oven.) 3.4 VISCOSITY 15 - 25 s (FLTM BV 103-01, 69 kPa line pressure) 3.5 WEIGHT PER VOLUME 1.14 - 1.26 kg/L (ASTM D 816) The weight tolera
5、nce for any one supplier shall be +/- 0.02 kg/L based on the recorded weight of his original approved production sample. 3.6 TENSILE STRENGTH, min 10.3 MPa (ASTM D 412, Die C) Elongation, min 300% 3.7 HARDNESS, DUROMETER A 50 - 60 (ASTM D 2240) ENGINEERING MATERIAL SPECIFICATIONESB-M4D148-APrinted c
6、opies are uncontrolled Copyright 2005, Ford Global Technologies, LLC Page 2 of 2 3.8 ADHESION The adhesion of the cured plastisol coating shall be such that it resists peeling from the metal bonding surface. The ability to readily strip this coating shall be basis for rejection. Good adhesion is ind
7、icated by a film which offers considerable resistance to stripping and breaks at the bond line. Test Method: Intersecting cuts are made with a knife through the coating so as to form a 30angle. The tip of the knife is inserted between the coating and the metal at the intersection. The coating is hel
8、d firmly to the knife blade and pulled upward slowly. 3.9 LOW TEMPERATURE FLEXIBILITY No cracking or evidence of failure Test Method: Coat a metal coupon 25 x 200 x 0.91 - 1.07 mm with the primer, ESB-M6J60-A, and the plastisol. Cure as recommended in para 5.3. The specimen is then conditioned for 1
9、6 h in a cold chamber at -29 C. The assembly is bent 180around a temperature conditioned 25 mm diameter mandrel. 3.11 CHEMICAL RESISTANCE The cured plastisol shall be resistant to acids, alkalies, oils, fuels and any other media encountered in normal service life. 3.12 TOXICITY Shall be nontoxic and
10、 shall not cause skin rash or irritation to exposed personnel in production operation. The solvents, benzene and chlorinated hydrocarbons are considered toxic and their use is strictly prohibited in formulating material to this specification. 5. GENERAL INFORMATION The information given below is pro
11、vided for clarification and assistance in meeting the requirements of this specification. 5.1 FLASH POINT, min 177 C (ASTM D 93) 5.2 APPLICATION The metal assembly to be coated is primed with ESB-M6J60 and cured. While the assembly is still hot, it is dipped into the plastisol for the desired film t
12、hickness and cured to obtain its optimum physical properties. 5.3 RECOMMENDED CURE CYCLE 15 minutes at 191 C 5.4 STORAGE Must be stored at temperatures below 32 C, away from all sources of heat. Heat greatly accelerates aging, effecting a partial cure, due to the greater solubility of the resins at elevated temperatures.
