Premixed frozen adhesives

First use of electrically conductive epoxies Premixed, frozen adhesives introduced by Ablestik Laboratories, Epoxy Technology, and Amicon Reduced ion content epoxies and polyimides Introduction of epoxy preforms First high-purity RTV silicone adhesives from G.E. and Dow Coming... 

See the later section in this article on Adhesive Processes for comments about storing premixed and frozen adhesives. Between Tgo and gei g, the liquid resin will react without gelation until its continuously rising glass-transition temperature becomes coincidental with the cure temperature, at which stage vitrification begins and the reaction may become diffusion controlled. Note that gei g is the temperature at which gelation and vitrification occur simultaneously.
