Henkel® LOCTITE 3D 3955 HDT280 FST

Henkel® LOCTITE® 3D

3955™ HDT280 FST* High Heat

*Flame, Smoke & Toxicity

Halogen-free flame retardant photopolymer. Printable at 60℃

LOCTITE® 3955™ is the engineering-grade 3D printing material that is mainly recommended for the aerospace industry but it can also be used in a wide range of applications from the automotive, or the manufacturing industries.

The first photopolymer 3D printing resin that passes vertical burn & aerospace
FST standards

Henkel® LOCTITE 3955 HDT HH is a halogen-free, high-performance, high modulus additive manufacturing material with excellent flexural and tensile physical properties. The material passes UL94 flammability V-0 and FST (AirBus AITM2-0002, AITM2-0007, AITM3-0005), and its high HDT allows it to withstand harsh environments with negligible deformation. It has been tested in QUV exterior weathering conditions (ASTM G-154 @ Cycle 1) for 1600 hours with less than a 15% change in flexural properties.
