WebOct 2, 2024 · In cold temperatures, the curing process of epoxy resin will still be successful, but it will take much longer. Before utilizing the epoxy resin in cold weather conditions, it is essential to check that it has been well-mixed. Suppose you are working with a two-part epoxy system. In that case, you must thoroughly combine the two … WebThe two epoxy components are mixed in accordance with the data sheet and cured at 23 °C. The curing process (without post-curing) is studied as a function of time. In addition, tests with 5% more and 5% less hardener than indicated in the data sheet are evaluated (Figure 2). The Tg is determined based on the DSC thermograms (see the example in ...
