    2、IBLE - STRUCTURAL - ESB-M2G218-A TWO COMPONENT 1. SCOPEThe material defined by this specification is an epoxy resin base, two component, roomtemperature or heat curing, structural adhesive. Substrates must be free of contamination foroptimum adhesion properties.2. APPLICATIONThis specification was r

    3、eleased originally for material used to bond component parts of theoutside thermometer. The substrates involved are stainless steel to acrylic, acrylic to acrylic andacrylic to chrome flashed zinc die casting.3.

    6、, NAENGINEERING MATERIAL SPECIFICATION ESB-M2G218-A Page 2 of 3 Copyright 2002, Ford Global Technologies, Inc. Test Method . Prepare 1 x 3 in (25 x 75 mm) test samples from acrylic and stainless steel (para 5.3.8) and solvent clean one surface free from contamination (isopropyl alcohol for the acryl

    7、ic and acetone for the stainless steel). Prepare 45 acrylic and 15 stainless steel samples. . Mix the epoxy adhesive in the weight proportions of 5 parts of base to 7 parts of accelerator (para 5.3.5). Prepare no more than 100 g of mixed adhesive and use within 1 h. . Assemble 0.5 in (13 mm) overlap

    8、 shear specimens using the cleaned surfaces and control the adhesive bond line thickness to 0.008 - 0.010 in (0.20 - 0.25 mm). Prepare 15 acrylic to acrylic and 15 acrylic to stainless steel assemblies. Maintain the overlap shear bond areas at the controlled thickness for 48 h at 23 +/- 2 C prior to

    9、 normal test and/or environmental exposure. Determine the adhesion in a tensile tester operated at 0.1 in (0.25 mm)/min. The average of 3 test specimens is to be recorded as the bond strength. 5. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting

    10、the requirements of this specification. 5.1 CAUTION This material contains epoxy resins and curing agents that under certain conditions of use could be considered toxic. Prolonged and repeated skin contact with this material should be avoided. If skin contact occurs, the material should be removed w

    11、ith soap and water. Tools, equipment and fabricated parts can be cleaned with solvents such as Xylol (M-14J245) or Chlorothene (M-5B58). 5.2 MIXING PRECAUTION Care should be exercised in the handling and storage of these materials. Low temperatures affect the cure rate of the mixed adhesives and the

    12、 base should not be catalyzed at temperatures below 16 C. 5.3 COMPONENT PROPERTIES 5.3.1 Color Base White Hardener Gray ENGINEERING MATERIAL SPECIFICATION ESB-M2G218-A Page 3 of 3 Copyright 2002, Ford Global Technologies, Inc. 5.3.2 Viscosity at 23 +/- 2 C (Brookfield RVF, #7 spindle, 20 rpm) Base 7

    14、Life (after mixing), min 60 minutes 5.3.7 Storage Stability The material shall be stored at temperatures below 27 C away from all sources of heat and sunlight. Heat greatly accelerates aging. Under these storage conditions, the minimum shelf life of the material shall 3 months. When these materials

    15、are stored at temperatures below 23 C, they shall be conditioned at room temperature prior to application. Adequate conditioning permits the material to obtain its optimum application properties. These materials are reactive with moisture which may be present in the atmosphere and, therefore, should be stored in tightly closed containers at all times in order to insure maximum storage stability. 5.3.8 Material Identification Acrylic ESF-M4D9-A Stainless Steel SAE 30304
