Abstract:

Bond life studies continued to show the great influence of a coupling agent for increased bond life in aqueous environment. The alkali-deficient glass surface was the only example of good bond life in the absence of a coupling agent. The wetting of resin on glass was greater than water on glass, as indicated by the captive bubble technique. Wetting studies of epoxy resin on various glass surfaces were continued. Detailed information on the size and shape of an air void near the glass surface is presented. The size was found dependent primarily on the time and temperature of curing the resin. The bubble shape and size was independent of the type of glass surface because, in all trials, the captive bubble technique indicated complete wetting by the resin and was unable to differentiate the type of glass surface. Miscellaneous wetting studies are also reported. Author
