Setting up a new bonding process and need to establish the curing schedule or your production process is set but experiencing fiber movement and needs to adjust curing temperature or time, here is a FOC TIP to validate your curing schedule:

Conduct DSC testing – We recommend you also conduct a Differential Scanning Calorimetry (DSC) test on each incoming lot of epoxy. Briefly, this test measures the outgassing of the epoxy sample, offering insight about whether it has been properly cured. Successful DSC tests, in conjunction with Telcordia GR-326, would give you high confidence that the epoxy is good and your processes are suitable.
