An Examination of Binder Systems and Their Influences on Burn Rates of High‐Nitrogen Containing Formulations

The examination of Laminac 4116/Lupersol and Epon 813/Versamid 140 binder systems, and their influences on burn rates of pyrotechnic formulations is described. Laminac 4116/Lupersol‐based formulations had shorter burn times and larger heat of explosion values compared to their Epon 813/Versamid 140 counterparts. An understanding of the chemical structures and approximate oxygen balances of these binder systems served to explain their burn time differences when used in pyrotechnic formulations. Bomb calorimetry of Laminac 4116/Lupersol‐ and Epon 813/Versamid 140‐based formulations provided heat of explosion values to further explain the burn time differences of the two binder systems used.
