DLP – LOCTITE 3843

LOCTITE 3843 is a high-strength photopolymer resin with excellent impact resistance and surface quality. It delivers thermoplastic-like mechanical performance with a matte black finish, making it ideal for functional parts that need to be tough, reliable, and visually appealing.

Key Material Facts:

• Excellent Impact Resistance – Withstands drops, shocks, and cyclic loading
• Thermoplastic-Like Toughness – Up to 66 MPa tensile strength and 43–46 J/m notched impact strength
• Great Surface Finish – Matte black appearance with minimal post-processing
• Moderate Heat Resistance – HDT of 60°C for light thermal loads
• Durable & Versatile – Balances strength, stiffness, and elongation
• Biocompatible – ISO 10993-5 & 10993-23 compliant

Common Applications:

• Arial Drone Frames, Sensor Mounts, Landing Struts
• Brackets, clips, and housings
• Functional prototypes and end-use parts
• Jigs, fixtures, and tooling aids
• Consumer product enclosures
• Impact-resistant snap-fits and mechanical components
