2、ERMOPLASTIC BONDING ESB-M3G41-A 1 SCOPE The material defined by this specification is a flexible, dry film adhesive tape composed of synthetic elastomers and various thermoplastic and thermosetting resins. 2. APPLICATION This specification was released originally for material used for bonding produc
3、t name plates on scuff plates as well as exterior decorative finishes to chrome plated die castings. The bonds are made by heat and pressure activation. 3.

7、of (2) 4-1/2 x 12 in (174 x 305 mm) pieces of 0.030 in (0.76 mm) AA-5052-H32 aluminum using first toluol (M-14J 242) and then acetone (M-1021). The area may be considered free of oils and greases when there is no haze remaining on the metal. Apply the bonding tape to the cleaned area of one panel. L
8、ay the cleaned bond area of the second panel over the first, making a bond area 1/2 wide x 12 in long (13 x 305 mm). Apply a pressure of 150 psi (1.0 MPa) to the bond line using a laboratory press or other suitable means and bring the bond line temperature to 191 C. Maintain at that temperature for
9、10 minutes. Remove the pressure and allow the panel to cool 4 to 24 h at 23 +/- 2 C. Cut the panel into 1 in (25 mm) wide strips using a band saw. This will provide specimens 8-1/2 in (216 mm) long with a 1/2 in (13 mm) overlap bond. Pull the specimens at a rate of 0.1 in (25 mm)/min and double the
10、load reading to compute and record the load in psi (or MPa). An average of 3 samples shall be used to obtain the results. Subject three 1 in (25 mm) specimens to each of the above aging tests. 3.8 90 PEEL ADHESION, min 3.8.1 Normal 5 lb/in (880 N/m) 3.8.2 Aged Peel Adhesion 7 days at 38 C and 95-100
11、 R.H. 5 lb/in (880 N/m) 7 days immersion 5% salt solution 5 lb/in (880 N/m) Test Method: Clean 1 x 7 x 0.010 in (25 x 178 x 0.25 mm)/min strips of AA3003-H14 aluminum using first toluol (M-14J242) and then acetone (M-1021). The strip may be considered free of oils and greases when there is no haze
12、remaining on the metal. Panels of AA-5052-H32, 0.030 in (0.76 mm) aluminum 2 x 9 in (50 x 230 mm) are prepared in the same manner. Apply the bonding tape (1 x 6 in (25 x 150 mm) strips) to the 2 x 9 in (50 x 230 mm) aluminum panel and carefully lay the 1 x 7 in (25 x 178 mm) aluminum strip over it.
13、Apply a pressure of 150 psi (1.0 MPa) to the bond line using a laboratory press or other suitable means and bring the bond line temperature to 197 C. Maintain at that temperature for 10 minutes. The above procedure will provide a bond area 1 x 6 in (25 x 150 mm). Peel the samples at a rate of 12 in

An average of 3 samples shall be used to obtain the results. Subject 3 specimens to each of the above aging tests. 3.9 FLAM
15、MABILITY, max 4 in (101 mm)/min (FLTM BN 024-02, without the lot sampling plan) In addition, the test specimen shall not exhibit any flashing or sudden flaming on either surface in excess of the above max value. 5. GENERAL INFORMATION The information given below is provided for clarification and ass
16、istance in meeting the requirements of this specification. 5.1 SOLVENT RESISTANCE The cured film shall not soften, swell or dissolve when immersed for 5 minutes in aliphatic hydrocarbons (light petroleum naphtha, M-14J147 or M-14J148) or aromatic solvents such as toluol or xylol, M-14J242 or M-14M245.
