LOCTITE, a brand of the German company Henkel, is recognized worldwide as a leader in adhesives, sealants, and surface treatments. Its pioneering technologies offer best-in-class solutions that deliver durable, high-performance, and consistent results. LOCTITE strives to provide efficient adhesives that unlock the full potential of people and machines. LOCTITE 3D 3955 is a high-performance, halogen-free photopolymer resin with high modulus and excellent flexural and tensile strength properties. This material meets the demanding UL94 V-0 flammability requirements as well as the requirements of the Aerospace FST standard (Airbus AITM2-0002, AITM2-0007, AITM3-0005). Thanks to its high heat deflection temperature (HDT), it remains largely dimensionally stable even in extreme environments. It is the first 3D photopolymer to pass both vertical burn tests and aerospace FST standards. Parts printed with LOCTITE 3D 3955 exhibit excellent surface quality and are therefore particularly suitable for use in the aerospace and rail industries, especially for connectors and interior components. The advantages of this material include fire safety, halogen-free composition, and outstanding physical properties in terms of flexural and tensile strength. It opens up application possibilities in various sectors such as manufacturing, the automotive industry, and aerospace. LOCTITE 3D 3955 is ideal for HVAC components in aircraft, clips and connectors for control systems and cabinets, as well as for electronic enclosures and connections. Caution: The resin is solid at room temperature and must be heated to 60°C before printing!
