Product Description
Permabond® HL126 is a water-thin, extremely low-viscosity anaerobic threadlocker designed specifically for wicking into pre-assembled parts via capillary action. By penetrating tight-fitting metallic threads after assembly, it effectively locks fasteners in place to prevent vibration-induced loosening. Furthermore, its penetrating characteristics make it an ideal sealant for weld porosities, as the uncured material easily flows into micro-pores to form a durable, 100% solid environmental seal upon curing.
Key features
- Wicking grade viscosity: The ultra-low viscosity (10-30 cP) allows application post-assembly and enables deep penetration into micro-porosities and tight tolerances.
- Military and ASTM approved: Formulated to meet the stringent lot requirements of MIL-S-22473E (Grade AA), MIL-S-46163A (Type III Grade R), and ASTM D5363.
- Weld sealing capability: Excellent for sealing weld porosity; it wicks into the warm voids and cures rapidly without solvents to establish a new, pressure-resistant seal.
Applications / Suitable for
- Post-assembly locking of set screws, bolts, and fasteners
- Sealing weld porosity and casting micro-pores
- Acting as a tamper-proof agent for assembled joints
