Loctite 620 50 ml anaerobic green glue for fixing coaxial parts, medium to high strength, resistant to very high temperatures up to 200 ° C, DVGW compliant, for pins, bushings, bearings
Description
LOCTITE 620 50ml – Anaerobic Adhesive for High Temperature Connections
LOCTITE 620 is a single-component, high-quality, high-viscosity anaerobic adhesive designed for retaining coaxial components. The product cures in the absence of air, in the gaps between tightly fitting metal surfaces. It is characterized by medium to high mechanical strength and excellent resistance to high temperatures up to 200°C.
Main advantages of LOCTITE 620
- High resistance to temperatures up to 200°C.
- Medium to high mechanical strength.
- Ideal for securing dowel pins, bushes in pump housings and bearings in gearboxes.
- Prevents loosening and leakage under static and dynamic loads.
- High viscosity product for filling larger gaps.
- Curing can be accelerated by using LOCTITE 7471™ or 7649™ activators.
Product properties
- Technology: Acrylic.
- Chemical type: Methacrylate ester.
- Form: Green liquid.
- Single component – no mixing required prior to use.
- High viscosity – excellent gap filling.
- Cure: Anaerobic, optional activator.
Typical applications
- Locking pins in housings.
- Installing bushes in pump housings and gear housings.
- Locking bearings in gearboxes.
- Applications requiring high temperature and mechanical stress resistance.
