Coatings braid analyses

Rubber-toughened epoxy resins have been characterized by their resin and rubber glass transition temperatures (57) using torsional braid analysis (TEA). These are reported in the literature as eTg and rTg, respectively. The Torsional Braid Analyzer has also been used to characterize ATBN-modifled coatings regarding transition temperatures. 

An alternative method for examining the dynamic mechanical properties of liquids is to coat them onto an inert support (typically a glass fibre braid). This measurement is termed Torsional Braid Analysis and does not provide quantitative modulus measurements since it is difficult to decouple the response of the substrate from that of the sample.
