SCOPE The materials defined by these specifications are glass cleaners/adhesion promoters that deposit monomolecular films and also remove surface contaminates. 2. APPLICATION These specifications were released originally for materia
4、ls used to clean and condition windshield glass prior to the application of adhesion promoting primer ( WSS-M2G314-B2). (These primers should be applied by means of a brush, felt or other suitable applicator. 2.1 MANUFACTURING PROCESS RECOMMENDATION These primers are moisture sensitive and require s
5、pecial handling for manual and automated process. Please contact supplier or the Material Engineering for current process standards. Approved suppliers are responsible for maintaining the accuracy and relevancy of these process parameters (in their Process Standard). Approved suppliers must submit a
6、ny changes to these process parameters in a timely manner (within 30 days) for review and approval by Materials Engineering, Vehicle Operation, and Product Development Engineer. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to t

9、n sample (see para 4.3). 3.5 DRYING RATE, max WSB-M5B280-C 1 minute WSB-M5B280-C2 1 minute WSB-M5B280-C3 10 minutes Test Method: Apply a 0.008 - 0.013 mm film of primer 25 mm wide to a 75 x 75 mm clean glass plate. To determine the primer drying rate, immediately at rapid intervals, dab the primer f
10、ilm with a wad of absorbent cotton. Observe if any of the cotton fibers adhere to the primed surface. Record the drying rate, as the time elapsed from the initial primer application until the cotton fibers do not adhere to the primer. Note: The drying rate is longer for the C3 suffix material due to
11、 the type of solvent. C4 is a one step clear primer and thus has a different drying rate. Actual differences in drying rate as processed through the assembly plant are negligible. 3.9 STORAGE STABILITY Shall be stored at ambient room temperature below 35 C, away from all sources of heat such as oven
12、s, direct sunlight etc. The material should not be stored outside. Under these storage conditions, the maximum shelf life of the material in unopened containers shall be six (4) months from date of receipt at Ford Motor Co. Material may not be used after the expiration date unless the supplier has g
13、iven written documentation to Materials Engineering and the affected Manufacturing Plant that the material conforms to requirements outlined in the material control plan. The supplier shall also indicate in the letter the number of additional days the material will be usable. ENGINEERING MATERIAL SP
14、ECIFICATION WSS-M5B280-C/C3 Printed copies are uncontrolled Copyright 2009, Ford Global Technologies, LLC Page 3 of 4 3.10 QUALITY The material shall be a smooth, homogenous mixture free from foreign materials and properties detrimental to normal production operations. 3.11 NON-INTERCHANGEABILITY OF

Functional trial results must be approved by the affected assembly operation and Design Engineering. Results shall be made available to Materi
17、als Engineering prior to material approval and release. 4.
