Description

For securing & sealing threaded connections. Vibration & impact resistant. Outstanding media/heat resistance. Hardening in uncleaned locations.

Forch K121 Thread Lock High Strength Red 50ml is a premium-grade additive designed for securing and sealing threaded connections that normally do not need to be released. It is vibration and impact resistant, providing outstanding media and heat resistance. The product hardens even in unclean surfaces, although the cleaner the surface, the stronger the connection. Its high-strength formulation can only be released using special tools or by heating to +300 °C. Key parameters include: Viscosity (25°C): 400-600 mPas, Density (25°C): 1.1 g/cm³, Temperature resistance: -55 °C to +150 °C, Max gap filling: 0.15 mm, Breakaway torque: 28-35 Nm, Shear strength (DIN 54452): 15-20 N/mm², Touchable consistency: 10-20 min, Functional consistency: 1-3 hours, Final consistency: 5-10 hours, Max thread: M20.

Benefits

  • Prevents loosening from vibrations and impacts
  • High temperature resistance
  • Ideal for use on bolts, screws, and nuts for a long-lasting hold
  • Provides secure fitting for safety-critical applications
  • Hardened connections can be disassembled with special tools or heat.

Technical

For best results, ensure that the threads are clean, free from oil, and contaminants. Although Forch K121 can harden on unclean surfaces, cleaning will enhance bonding strength. Apply a few drops of the product onto the fastener thread and tighten as required. The product will start to set within minutes and achieve full functional strength within 1-3 hours and full cure within 5-10 hours. Special tools or heating to +300 °C are required to disassemble.
