3MT Scotch-WeldT EC-3550 B/A FST (Fire, Smoke and Toxicity) is an extrudable, two part, low density, structural void filling compound based on epoxy chemistry. It is designed for use on interior honeycomb sandwich structures as edge close-out and corner reinforcement, as well as local reinforcement for mechanical fixation or complex gap filling. The void filler is compatible with metal and non metal constructions that are typically found in aircraft interiors. The cured material has excellent FST properties, based on a halogen and heavy metal free system. It has good processing attributes due to its easy storage, handling, extrudability, filling, grinding, and painting abilities.
