What your process engineer actually checks

Validated, load-and-print cure profiles

Every resin ships with a tested exposure/cure profile for the printers we sell and a datasheet covering viscosity, cure energy, mechanical properties, and shelf life. Dial the build in once, reorder the same chemistry.

About this product

LOCTITE 3D 3955 FST Black: The Aerospace-Grade Flame-Retardant Resin Redefining Flight Safety

As the first 3D printable photopolymer to pass stringent Airbus AITM standards (2-0002, 2-0007, 3-0005) and UL94 V-0 certification, LOCTITE 3955 FST Black delivers unmatched fire safety for critical aerospace, rail, and automotive applications. With a record-breaking heat deflection temperature exceeding 300°C at 0.455 MPa, this halogen-free material withstands extreme environments where traditional polymers fail.

Applications

Aerospace

  • Cockpit HVAC ducts

  • Engine bay clip fasteners

  • Cabin connector housings

Rail & Automotive

  • EV battery thermal barriers

  • High-speed train interior panels

  • Under-hood sensor mounts

Why Engineers Specify 3955

  • Replace Metals: 68% weight reduction vs. titanium fasteners

  • Accelerate Certification: Pre-validated to FST/UL/IEC standards

  • Eliminate Halogens: Zero bromine/chlorine emissions during fires

  • Extreme Environment Proven: Stable after 6-week salt spray (ASTM B117)

Storage: 8-30°C in sealed containers | Shelf life: 12 months

Industry First: The only photopolymer qualifying for permanent Airbus interior components.
