Permabond® HH167 is a high viscosity gap filling silver paste, which can be used for repairing metal machinery parts. It is ideal for repairing worn shafts, broken threads, damaged keyways and splines. Permabond HH167 has excellent chemical and temperature resistance. NB. This adhesive is only suitable for gaps <0.5 mm and will not cure on the outside of a joint.
Features
