(HTHP Transmission) AN21-07: In-situ high temperature, high pressure analysis of resin-based adhesives for prediction of final properties

Monitoring the change in FTIR characteristic peaks of a resin sample at varying temperatures

Discover a method for high temperature, high pressure analysis of viscous resins and pastes in the Specac HT/HP Cell.

FTIR can accurately determine the change in functional groups and the adsorption process of a material, allowing rapid screening of samples prior to further investment of R&D resources. To replicate a material’s on-site or real-life condition, it is necessary to carry out in-situ testing because material properties change depending on temperature and pressure.

It is vital to pick the right in-situ high temperature high pressure accessory for specific tests and samples. Specac’s High Temperature High Pressure Cell (HTHP) is a tri-modal accessory, especially suitable for the in-situ analysis of solid powders, viscous colloids, pastes, and adhesives by transmission mode, and dark-coloured materials by reflectance mode. The HTHP can reach a maximum temperature of 800 °C for sample analysis, and its separately heated windows reduce interference from condensation. The temperature ramp rate can be adjusted on the controller to quickly reach the desired temperature.
