WebApr 1, 2011 · At temperatures above the Tg, the adhesive’s coefficient of thermal expansion(CTE) rises rapidly as the polymer matrix expands. This increase in space can result in unacceptable part movement or even open up the polymer matrix to chemical or environmental attack. While Tg is a good criteria for initial product selection, other … WebLow Viscosity, High Strength Adhesive Materials with Low CTE. Small Business Concern . Firm: Nanosonic, Inc. ... The aliphatic epoxy adhesive formulations have viscosities <10 Poise and the fully cured networks display glass transition temperatures higher than 70 °C using cationic photo initiation at ambient conditions. The adhesive ...
