DLP – LOCTITE IND249

LOCTITE IND249 is a semi-flexible black resin with excellent impact resistance and a smooth matte finish. It offers a unique balance of stiffness, ductility, and surface quality — making it ideal for snap-fit components, enclosures, and mechanically loaded parts.

Key Material Facts:

• Impact Resistant – High toughness with energy-absorbing capability
• Semi-Flexible Performance – Combines moderate elongation (51–57%) with rigidity
• Superior Surface Finish – Clean, matte black appearance with minimal post-processing
• Reliable Mechanical Strength – 48–51 MPa tensile strength, 2.2 GPa flexural modulus
• Chemical Resistance – Excellent resistance to fluids like mineral oil and brake fluid
• Biocompatibility Certified – ISO 10993-5 compliant

Common Applications:

IND249 is well-suited for components requiring snap, flex, and durability:

• Snap-fit housings and enclosures
• Shock-absorbing brackets and supports
• Semi-rigid ducts, guides, and protective covers
• Functional prototypes and structural end-use parts
• Automotive and industrial fixtures exposed to mechanical stress
