Euro-Tech are a specialist Loctite distributor and can supply and export the full range of Loctite products, including items such as those listed below.
Threadlockers
A threadlocker is a single component liquid or semi-solid adhesive. Threadlockers cure at room temperature to a hard solid thermoset plastic when applied between steel, aluminium, brass and most other metal surfaces. They cure in the absence of air. The adhesive completely fills the gaps between mating threads to lock threads and joints.
Benefits:
- Locks mating metal threads to prevent loosening from vibration and shock
- Seals against fluids and corrosion
- Provides lubricity to achieve controlled torque during assembly
- Prevents galling and seizing for reliable disassembly
