Curable Fluorocarbon Resin-Based Compositions

Incendiaries based on volatile metal fuels yield large diffusion flames and thus lead to high levels of radiant intensity. In contrast, incendiaries based on non-volatile fuels undergo solid-phase combustion and predominantly transfer heat by conduction and convection. Pyrotechnic incendiaries can be either fuel rich or provide a surplus of oxidizer to facilitate combustion of a target substrate. 

Compositions based on glycidyl methacrylate and 1,1,7-trihydrododecafluoro methacrylate as a binder and an oxidizer and various metals such as Zr, Ta, U and cerium mischmetal have been proposed [4]. 

734 wt% 1,1,7-Trihydrododecafluoroheptyl methacrylate 4.563 wt% Glycidyl methacrylate 2.303 wt% 2-Ethylhexyl methacrylate 0.130wt% Butylene dimethacrylate 

The aforementioned composition was cured with 0.435 part benzoyl peroxide. After polymerization, the composition would burn slowly. After a delay of 30 min, the material undergoes another exothermic reaction that brought the material to incandescence. 

A system proposed as Napalm substitute incendiary is given below [5].
