2、IMER, ADHESION - URETHANE STRUCTURAL ADHESIVE ESB-M2G190-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a chemically reactive, non-flammable, solvent release, air drying, adhesion wash primer. 2. APPLICATION This specification was released originally for a mat
3、erial used for priming FRP (glass fiber reinforced polyester) prior to the application of structural adhesive. The primer air cures at 23 +/- 2 C and does not require heat cure prior to or after adhesive application. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material supplie
4、rs and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1 COLOR Red or Orange or as specified 3.2 VISCOSITY Shall be water thin for easy wash priming of the FRP substrate. 3.3 SOLIDS 2 - 3% (ASTM D 2046, except heat at 70 C for 10 min in
5、a mechanical convection oven) 3.4 EVAPORATION LOSS Shall not be drawn off in volumes that will not be utilized within 8 hrs. Material shall be maintained in closed containers at all times. ENGINEERING MATERIAL SPECIFICATION ESB-M2G190-A Page 2 of 3 Copyright 2014, Ford Global Technologies, Inc. 3.5
6、DRYING RATE at 23 +/- 2 C, max 2 minutes Test Method: Apply a light wet film (approximately 0.0003 - 0.0005 in (8 - 13 m) to a flat surface of an FRP panel. The primer must be dry to the touch within the specified time limit. The applied primer must flash off at least one minute before adhesive is a
7、pplied, but must not be reapplied if the open time exceeds 16 hrs. at 23 +/- 2 C. 3.6 COVERAGE No skips or bare spots Test Method: Apply the adhesion primer in a light wet coating with no skips or bare spots evident. The primer may be applied by either brushing, spraying or wiping. 3.7 STORAGE STABI
8、LITY The material shall be stored at temperatures below 38 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 be 3 months. When these materials are stored at temperatures below 23 C, they shall be
9、 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
10、 in order to insure maximum storage stability. 3.8 QUALITY The material shall be a smooth homogeneous mixture, free from foreign materials and properties detrimental to normal production operations. 3.9 WEIGHT PER VOLUME 10 - 11 lb/gal (1.20 - 1.32 kg/l) The weight tolerance for any one supplier sha
11、ll be +/- 0.2 lb/gal (+/- 0.024 kg/l) based on the recorded weight of his originally approved production sample per ASTM D 816. 5. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 MOISTURE Do not dilut
12、e. As received, material is highly sensitive to moisture. To avoid moisture contamination, containers must be tightly sealed except when material is removed for use. ENGINEERING MATERIAL SPECIFICATION ESB-M2G190-A Page 3 of 3 Copyright 2014, Ford Global Technologies, Inc. 5.2 HANDLING The container
13、should be gently agitated before use and may be under positive pressure. Open with care. 5.3 CLEAN UP Methylene Chloride or Methyl Ethyl Ketone may be used for immediate cleanup. The degree of difficulty in removal of the applied primer increases with time. 5.4 CAUTION Materials used in this product
14、 may cause skin irritation. Hands and eyes should be protected when handling the primer. In case of contact, flush skin or eyes with plenty of water for at least 15 minutes. For eyes, medical attention should be provided. 5.5 TOXICITY Under certain conditions of use, this material could be considere
15、d toxic. The Manufacturing Engineering Department shall notify both the Plant Security and the Safety Units of its presence in the plant. Company activities shall use this material only as recommended by the Security and Safety Units, and using activities shall insure that protective devices are available and used. 5.6 FLASH POINT None The solvent Methylene Chloride is not flammable. 5.7 SURFACE PREPARATION The FRP surface must be free of contamination such as mold release, dirt and grease prior to the primer application.
