2、NG WSS-M99C45-A4 1. SCOPE The material defined by this specification is a quick-drying, water-based surfactant and polymer mixture. When dry, the material leaves a slightly tacky surface with no appreciable residue. 2. APPLICATION This specification was released originally as an assembly aid to lowe
3、r the insertion efforts for exhaust isolators and rubber hoses. The quick drying property is particularly suitable for hoses where initial pressurization and blow off requirements apply. 2.1 APPROVAL INFORMATION This specification was released to allow this material to be purchased by Ford Purchasin
4、g for use in a Ford facility. The specification number is also the part number in WERS. Material performance and selection is determined by line trials and design verification testing on the components for which it is used. Approved Source: International Products Corp.

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 COLOR Clear (Visual) 3.3 DENSITY 0.995 - 0.999 g/mL (ASTM
6、 D 1475) 3.4 pH 9.8 11.3 (ASTM E 70) 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. Material approved to this specification has the following typical properties. Note: This material is not designed to
7、 be diluted with water. Dilution will decrease lubricity and may alter the typical properties listed below. 4.1 TOTAL SOLIDS 5.0% (ASTM D 460, Method A) ENGINEERING MATERIAL SPECIFICATION WSS-M99C45-A4 Printed copies are uncontrolled Copyright 2011, Ford Global Technologies, LLC Page 2 of 2 4.2 VISC
8、OSITY AT 25 C 100 cP (Brookfield Viscometer, #2 spindle at 100 RPM) 4.3 LUBRICITY (Insertion force, 5/8 inch ID heater hose over rigid PVC) Laboratory tests show up to a 40% reduction in insertion force when compared to rubber hose without lubricant. 4.4 DRYING CHARACTERISTICS The reference drying t
9、ime for this material is at least 20 minutes. The actual drying time depends on the amount applied and the surrounding environment. 4.5 ELASTOMER COMPATIBILITY, (ISO 1817/ASTM D471, 22 hours immersion at 23 +/- 2 C) Nitrile Neoprene Butyl EPDM Viton Silicon Natural Volume Swell in lubricant 0.5% 0.7
