Glass transition phase
WebGlass transition Non-crystalline materials such as polymers, on the other hand, have a glass transition. This is where completely or partially amorphous polymers change from a highly viscous or rubber-elastic, flexible state to a glass-like or hard-elastic, brittle state. WebDens-Glass Gold should not be laminated to masonry surfaces; use furring strips or fram-ing spaced at manufacturer’s specifications. Dens-Glass Gold may be used in DEFS …
