DLP – LOCTITE 3955 FST
LOCTITE 3955 FST is a halogen free, high performance, high modulus material with excellent flexural and tensile physical properties. It passes UL94V-0 flammability requirements and FST (AITM2-0002, AITM2-0007, AITM3-0005) and its high HDT allows it to withstand harsh environments with negligible deformation. Parts printed with LOCTITE 3955 FST showcase an outstanding surface finish making it ideal for connector and interior parts for aerospace and rail.
Key Material Facts:
- Flame Resistance: LOCTITE 3955 FST is designed to meet rigorous flame resistance standards. It is formulated to inhibit flame propagation, making it ideal for applications where safety in the event of a fire is critical. Passes flammability 2×10 second Vertical Burn and FST (AirBus AITM2-0002, AITM2-0007, AITM3-0005)
- Low Smoke Emission: The resin is specifically developed to minimize smoke generation during combustion, which is important in confined spaces like airplanes, vehicles, or industrial environments where visibility is crucial during a fire event.
- Low Toxicity: LOCTITE 3955 FST is designed to emit minimal toxic fumes when exposed to heat or flame. This property is vital in ensuring that any parts printed with this material are safer in situations where they might be exposed to high temperatures or fire.
- Mechanical Strength: While primarily focused on flame resistance, LOCTITE 3955 FST also offers good mechanical properties, including tensile strength, impact resistance, and flexural strength. This makes it suitable for both functional prototypes and end-use parts that need to withstand mechanical stress while meeting fire safety requirements.
- Durable and Weather Resistant
Common Applications:
- Aerospace: LOCTITE 3955 FST is widely used in the aerospace industry for producing functional parts such as interior components, structural elements, and enclosures that must meet strict fire safety standards. Its flame resistance, low smoke, and low toxicity are crucial for the safety of passengers and crew.
- Automotive: In the automotive industry, the resin is used for components that need to withstand high temperatures, such as parts in the engine compartment, interior elements, and electrical connectors. Flame-resistant materials are particularly important in ensuring vehicle safety in the event of a fire.
- Electronics: LOCTITE 3955 FST is used to produce enclosures, housings, and other electrical components that require flame-retardant properties. This is especially important for consumer electronics or industrial electronics that might be exposed to electrical short circuits, heat, or fire.
- Marine: In the marine industry, LOCTITE 3955 FST can be used for parts exposed to high heat or fire hazards, such as housings, covers, and enclosures that meet marine safety standards for flame resistance and low smoke emission.
- Military and Defense: The resin is also suitable for producing parts used in military and defense applications, where flame retardant properties are crucial for safety in extreme conditions, including aircraft parts, armored vehicles, and personal protective equipment.
- Railway: LOCTITE 3955 FST can be used for railway components such as interior panels, electrical connectors, and protective covers that need to meet stringent fire safety standards for use in trains and other rolling stock.
