Scotch-Weld™ 3450 FST is an extrudable, heat curing, low density, structural void filling
compound based on epoxy chemistry. It is designed for use on interior honeycomb sandwich structures as edge close-out,
corner reinforcement, as well as local reinforcement. The
void filler is compatible with metal and non metal constructions that are typically found in aircraft interiors. The cured
material has excellent fire, smoke, and toxicity properties, based on a halogen and heavy metal- free FST System. It
offers excellent chemical resistance and has best processing attributes due to its easy extruding, filling and grinding abilities.
