The TORC (Thermo-optical Oscillating Refraction Characterization) technique applies decades of know-how in optical instrumentation to thermal analysis in a novel and unique way. The technique requires minimal sample preparation at maximal tolerance for sample properties. You can determine the coefficient of thermal expansion, glass and phase transitions as well as polymerization for various samples: liquids, gels, pastes, and certain solids. For example: cured and uncured resins, adhesives, glues, etc. can easily be characterized. Both thermal and time-dependent processes can be monitored with minimal effort.
