Fire protection A new article focuses on the development of multifunctional, flame retardant epoxy gelcoat formulations based on phosphorus-containing, intumescent flame retardant (FR). The researchers prepared epoxy resin-based gelcoats with 5 %, 10 % and 15 % phosphorus (P) content using ammonium polyphosphate. They reached a 67 % reduction in peak heat release rate when they replaced a 1 mm thick non-FR gelcoat with a gelcoat containing 15 % P.
