LOCTITE 542 Metal Pipe Thread Sealant & Locking Compound Sealant
Basic Properties
LOCTITE 542 is a one-component brown acrylic sealant (dimethacrylate ester) with low viscosity (400-2,750 cP @25°C) and thixotropy. It cures anaerobically in confined metal thread gaps, specifically engineered for sealing and locking pipe fittings, specific gravity 1.06@25°C.
Core Characteristics
It forms a medium-strength seal resisting vibration-induced loosening. Key advantages include:
- 25N·m breakloose torque for M10 steel bolts
- Resistance to 125°C motor oil and brake fluid
- Thixotropy minimizes post-application migration
