MecSealant® Anaerobic Retaining Compounds are designed to seal and secure non-threaded cylindrical shaft-shaft liner assemblies. Anaerobic Retaining Compounds are used to fill inner voids between two components and cure to form a strong precision assembly. It can be applied manually or via a dispenser. Our retaining compound adhesives are available in four models with different ranges of strength, viscosity, temperature and other features.
Product Range:
- Low Viscosity – MRC 603
- Medium Viscosity – MRC 680
- High Viscosity – MRC 638
- Low Viscosity (High Temperature) – MRC 648
Packaging Size: 50mL/bottle
