EL-319 is a UV stabilized Halogen-Free Flame Retardant Epoxy Laminating System developed for use in fabricating parts or repairs on structures which require flame retardant, self-extinguishing properties with room-temperature curing capabilities. The EL-319-1 low 900 cps mixed viscosity is also suitable for vacuum infusion processes. This system is tested to comply with FAR/JAR 25.853(a) of the Federal Aviation Standards for aircraft interiors and other areas where flame retardant performance is needed. EL-319 resin is available with two hardener choices: EL-319 moderate work-life hardener for fast turnaround of production parts and repairs, or EL-319-1 long work-life hardener for laminating and vacuum bagging of large parts and repairs
