3、2G316-B5 PRIMERLESS TO SILANE BASED CLEARCOAT PAINT 1. SCOPE The material defined by these specifications is a one component moisture curing urethane adhesive which is primerless to clearcoat paint chemistries. 2. APPLICATION These specifications were released originally for material used in conjunc
4、tion with a two stage glass priming operation (primers identified per para 4) to bond glass windshields, glass rear windows and quarter windows to painted metal surfaces. These materials will bond primerless to e-coated surfaces that are contaminate free and can also be used in conjunction with meta
5、l flange primers. WSS-M2G316-B2 shall be used in assembly plants with silane based clearcoat painted metal surfaces baked only in direct fired oven. WSS-M2G316-B3 shall be used in assembly plants with non silane based clearcoat painted metal surfaces. It must not be used with silane based clearcoat
6、painted surfaces WSS-M2G316-B5 Shall be used in assembly plants where data has shown a compatibility with the assembly plants clearcoat chemistry. This material was originally released for silane based clearcoat painted metal surfaces baked in direct or indirect fired oven. 2.1 MANUFACTURING PROCESS
7、 RECOMMENDATION These adhesives are moisture sensitive and require special handling as outlined in Table 2. The process parameters listed in Table 2 cover the critical elements for these materials and are not all inclusive. Please consult with Materials Engineering for any questions. Approved suppli
8、ers are responsible for maintaining the accuracy and relevancy of these process parameters (in their Process Standard). Approved suppliers must submit any changes to these process parameters in a timely manner (within 30 days) for review and approval by Materials Engineering. ENGINEERING MATERIAL SP

REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materi
10、als (WSS-M99P1111-A). 3.2 UNCURED ADHESIVE PROPERTIES 3.2.1 Rheology (SAE J1524, rotational rheometer with 40 mm diameter parallel plates, 500 micron gap, 50 Pa/sec ramp, stress controlled rheometers use stress range 0 - 3500 Pa, strain controlled rheometers use strain range 0 - 100 sec-1, evaluate
11、material to highest stress of strain as the formulation will allow, report material batch/lot number, identify rheometer make and model, for each test condition report yield stress and submit plots for shear stress vs shear rate, submit plot for viscosity vs temperature at mid-range shear rate. 3.2.
12、1.1 Initial (as received) Test at 23 +/- 1 C Test at application temperature +/- 2 C Test over range 10 to 50 C at increments of 10 C 3.2.1.2 Aged (Age then test at 23 C and application temperature) 7 days at 40 +/- 1 C 90 days at 32 +/- 1 C The rheology variation for any one supplier shall be +/- 3
13、0%, based on the recorded rheology of the original approved production sample. The flow curves established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce flow curves that correspond to the refere
14、nce standard when tested under the same conditions. Final approval of material rheology for production shipments shall be made by the affected manufacturing activity. In all cases, the rheology shall be within the limits as identified on the material control plan. 3.2.2 Solids, min 98% (ASTM D 2834,
15、 except heat for 3 h at 100 +/- 3 C in a mechanical convection oven) 3.2.3 Ash, based on solids weight, max 21% (ASTM D 482) 3.2.4 Weight per Volume (ASTM D 816) The weight tolerance for any one supplier shall be +/- 0.02 kg/L based on the weight of the original approved production sample.

Apply a 76 mm long right triangular shaped bead of material 6 mm wide at the base and 15 mm high on a g
17、lass or steel panel. . Permit the panel to air dry for 30 minutes at R.T. in a plane 60 angle from the horizontal. Measure the sag. 3.2.6 Sensitivity to Alcohol CAUTION: Slight traces of alcohol will inhibit the cure of this adhesive. The use of alcohol or alcohol containing solvents is prohibited f
18、or cleanup or other uses. 3.2.7 Storage Stability Shall be stored at ambient room temperature below 40 C, away from all sources of heat, such as ovens, direct sunlight, etc. Shall not be stored outside. Under these storage conditions, the max shelf life to the material, from date of shipment from th
19、e supplier, shall be 3 months. The supplier must label each container to indicate the expiration date of the material, and production usage beyond the expiration date is not permitted. When stored at temperatures below 23 C, it must be conditioned at R.T. for 72 h prior to use. 3.2.8 Odor The materi
20、al must not have a toxic or noxious odor. After curing, the material must be relatively non-odorous as defined by the affected assembly plant. 3.2.9 Fogging Test (SAE J1756, 3 h 100 C heating, 21 C cooling plate, post test conditioning 1 and 16 hrs.) Fog Number, min 70% Any fog film present shall be
21、 examined for the formation of droplets or coalescence into a clear film. Such conditions, if present, shall be cause for rejection. Uncured and cured samples shall be tested. 3.2.10 Quality Shall be a smooth homogeneous mixture free from foreign materials and properties detrimental to normal produc
22、tion operation. 3.2.11 Non-Interchangeability of Materials Only approved materials, all from the same production (supplier) source, shall be used in conjunction with one another.
