SCOPE The material defined by this specification is a lead fr
3、ee vinyl based, self-leveling, paintable, heat curing sealer with (-B5) or without (-B4) expanding properties. 2. APPLICATION This specification was released originally for sealing exterior body seams, such as drip rail to roof ditch including a molding, and is intended for use over freshly baked el
4、ectrocoat primer. Acceptable paintability is achieved with or without primer surfacer on sealer. 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
5、RHEOLOGY Suppliers must submit flow characterization data to Ford Motor Company for flow modeling and process window determination. For a specified temperature range, the requested properties include, but are not limited to, viscosity, yield stress, apparent activation energy for viscosity and appar
6、ent activation energy for yield stress. This data constitutes the reference standard and shall be kept on file at the designated material laboratory. 3.3 SOLIDS 96% min (ASTM D 2834, except heat at 102 +/- 1 C for 3 h in a mechanical convectional oven. Save sample for next test, para 3.4) 3.4 ASH 36
7、% max (ISO 3491, Method A, 760 +/- 30 C) The ash content tolerance for any one supplier shall be +/- 5% based on the recorded ash content for their originally approved production sample. 3.5 WEIGHT PER VOLUME 1.35 -1.68 kg/L (ASTM D 816) The weight tolerance for any one supplier shall be +/- 0.02 kg
8、/L, based on the recorded weight of their original approved production sample.

9、 production shipments shall be made by the affected manufacturing activity. In all cases, the viscosity shall be within process limits as identified on the material control plan. The viscosity tolerance for any one supplier shall be +/- 10%, based on the recorded viscosity of the original approved p

11、, 43 oC, and after 2 weeks at 32oC Final approval of a specific material viscosity for production shipments shall be made by the affected manufacturing activity. In all cases, the viscosity shall be within specification limits. 3.7 FLOW RATE (Initial at 23 +/- 2 C and 20 300 mm after 90 days storage
12、 at 23 +/- 2 C and 32 +/- 2 C) The flow rate tolerance for any one supplier shall be +/- 10%, based on the recorded flow rate of the original approved production sample. Test Method: Block the 6.4 mm groove in the flow rate fixture (Fig. 1) 150 mm from the top edge. Fill the 150 mm upper portion of
13、the groove with material specified in this specification. Remove the block, allow material to flow for 30 minutes, then subject the test assembly to the minimum bake per para 4.3. Remove test assembly from heat exposure and measure the total amount of flow. Final approval of a specific material flow
14、 rate for production shipments shall be made by the affected manufacturing activity. In all cases, the flow rate shall be within limits identified on the Material Control Plan.

15、Shall not be peeled off in a continuous film. Test Method: Apply a ribbon of material, 25 x 200 x 3 mm on two electrocoated panels, identified per para 4.2. Subject one test panel to the minimum bake and the other test panel to the maximum bake identified per para 4.3. Evaluate adhesion by cutting a
16、 25 mm wide strip across the ribbon. Using the tip of a square spatula, lift the material, then attempt to hand peel material at 90 from substrate. Save test panels for heat resistance test, para 3.9, and corrosion resistance test, para 3.10. 3.9 HEAT RESISTANCE TEST No evidence of blistering, (336
17、hours at 70C) cracking, charring or other deleterious effects Test Method: Examine the test material prepared for Adhesion Test, per para 3.8, for any of the above conditions. 3.10 LABORATORY ACCELETRATED CYCLIC No corrosion or CORROSION TEST adhesion loss (CETP 00.00-L-467, 6 weeks) Evaluate materi
