A two-part, low-density, flame-retardant epoxy paste stored, mixed, applied and cured at room temperature for void-filling, edge sealing, corner reinforcement and gap-filling in honeycomb sandwich construction. High-viscosity, non-sag rheology allows applying to multiple parts at once and resists chip-outs; among the lightest extrudable/pumpable FR void fillers.
