The 3955 HDT280 FST resin from the Loctite family of flame retardant photopolymers is a high performance halogen-free flame retardant resin (UL94-V0) with excellent flexural and tensile physical properties, as well as a great surface finish. This resin has successfully passed the vertical burn tests and is fully compatible with aerospace FST standards (AirBus AITM2-0002, AITM2-0007, AITM3-0005). Parts 3D printed with this material exhibit no deformation in thermically harsh environments.

The 3955 HDT280 FST resin is the perfect material for the additive manufacturing of connector and interior parts for the aerospace and rail industries, for example HVAC components, clips and plugs for control systems, electronic housings, etc.
