Abstract : Hot water debonded the resin rapidly in the absence of a coupling agent or a special glass surface condition. The dominant mechanism of debonding was water penetration along the glassresin interface (edge). Bond life and wetting studies are summarized. Surface roughness appeared to promote wetting by water of the A-1100 treated glass surfaces. Four more contact angle measurements by the captive bubble technique are needed to complete the required wetting studies. Valuable refinements of the butt-joint tube method were advanced. The refinements included allowing the resin to shrink freely and eliminating the notch effect in the resin column design. Glass surfaces tested by mass spectrometry techniques to detect the presence of A-1100 are listed. Surface tension data for all test liquids used in the wetting studies are also presented. (Author)
