The present disclosure relates to an aqueous fire-retardant composition comprising particles dispersed in an aqueous phase, wherein the particles comprise a fire-retardant brominated epoxy polymer and an organic polymer comprising ionic dispersing groups. The present disclosure further relates to an aqueous fire-retardant coating composition comprising such fire-retardant composition, and to a substrate coated with a coating deposited from such coating composition.

A cover for an opening on the exterior of an aircraft that contains a fire-resistant, high-temperature tolerant foam encased in a cover made of an aramid fabric. The cover is friction-fitted to the interior of the orifice. The cover can contain one or more durable rings embedded in the fire-resistant, high-temperature tolerant foam meant to protrude outward from the rest of the cover of the body to contact an interior of the orifice into which they are inserted holding the cover in place with friction instead of fasteners.
