12、ion rubber base adhesive, and/or ESB-M2G148-A, high heat resistant adhesive, through more than 25% of the original material thickness. In addition, there shall be no through “spot“ bleeding, in any area of the material. Test Method: (1) Prepare a 12 x 12 in (300 x 300 mm) specimen. (2) Apply 15 - 20
13、 g of adhesive uniformly over the middle 12 x 12 in (300 x 300 mm) area of a 12 x 15 in (300 x 380 mm) phosphate coated and primed steel panel. (3) Place the sample on the treated surface of the panel, then roll with a 12 in (300 mm) roller weighing 5 pounds (2.3 kg), without applying additional pre
14、ssure. (4) Turn the panel upside down and rest the pad on 3 equally spaced rods. Each rod will have a 1/2 in (12.7 mm) diameter and be securely fastened to a 12 x 12 in (300 x 300 mm) masonite board. Place the assembly in a mechanical convection oven maintained at 102 +/- 2 C. Load the test panel wi
