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

Key Performance Data

Mechanical & environmental properties after 24h cure @22°C:

Industrial Applications​​:
- Hydraulic high-pressure fittings (pump/valve threads)
- Compressed air pipeline flanges
- Gas transmission pipe thread locking
