    The LOCTITE 3955 Resin

    The LOCTITE 3955 is the first 3D printing resin that passes vertical burn and aerospace FST standards. A high-performance, halogen-free material, 3955 has a high HDT that allows it to withstand harsh conditions with negligible deformation. The resin guarantees a great surface finish, which makes it great for connector and interior parts in the aerospace and rail industries.

    This material requires pre-melting!
