2,Shear Strength: The test method to evaluate adhesive tape cohesive strength. After adhere the tape strip on the test object and give it adequate pressure, hang a certain weight on it in vertical direction, to measure the adhesive displacement or the falling time. Test Condition: JIS Z 0237 11 Standard Adhered Object: No.280 water-fast emery paper polished No.SUS304 steel panel Adhered Area: 20mm× 20mm Test Temperature: 40℃ Weight: 1 Kg Time for Testing: 1 Hour |

3, Stainless Steel Ball Initial Strength: The test method to evaluate adhesive tape adhesion ( initial adhesion ). J.DOW Measurement: Adhered adhesive strip on the 30°angle slope, release stainless steel balls which the diameters from 2/32 inch to 32/32 inch from the slide-up area, to observe the number of the biggest ball adhered on the slope. Test Condition: JIS Z 0237 12 Standard Test Environment: 23℃/ 65% RH Slide area length: 100mm Distance Slided: 100mm |
