APPLICATION These specifications were released originally for single component industrial quality adhesives formulated for bonding all metals, most rubbers and many plastics. See attached strategy table for details. LIMITATIONS: Surfac
3、es must be clean, free of oil and debris prior to application. When mixed substrates are used, material selection should be based on maximum bond strength of weakest bond to substrate. I.E. Substrates: EPDM Rubber on Steel. The adhesive bond strength of steel is superior to EPDM Rubber. Therefore, t

REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material sup
13、pliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 CONTROL ITEMS Control items must be run on every lot of material, control of these items must be represented in the PFMEA and control plan. After the review and sign-off of the
14、 control documents (PFMEA, CP, and SPC data) for a significant number of lots, the frequency of the testing can be reduced as agreed upon by the Materials Engineering representative. Periodic review of the data is necessary to determine if the process has shifted, retesting of para 4.0 parameters ma
15、y be requested by Materials Engineering if a significant shift has occurred. 3.2.1 Lot to Lot Testing on B1 materials 3.2.1.1 Viscosity, mPas 100 - 200 (BS 5350 Part B8 Physica cone and plate, cone MK22, shear rate 1000s-125 + 0.5 C) 3.2.1.2 Tensile Strength, N/mm2, min 1.8 (ASTM D 1414-03, DIN 5350
