Product Introduction
Permabond® HM129 is a high-strength, medium viscosity anaerobic threadlocker and sealant. This adhesive cures in the absence of air between tight-fitting metal parts and provides fast and reliable curing on steel, cadmium, zinc, and other plated fasteners, ensuring permanent assembly and preventing loosening and leakage.
PERMABOND® HM129 Features
- Oil tolerant
- Vibration resistant
- Lubricates threads for easier assembly
- Provides corrosion protection
- Solvent-free
PERMABOND® HM129 Applications
- Locking and sealing bolts, nuts, and screws
- Permanent assembly applications
- Vibration-prone environments
- Corrosion protection in metal assemblies
