Product Description

B638 – HIGH STRENGTH RETAINER

Bondloc B638 is a high strength retaining compound designed for the bonding of cylindrical fitting parts, with bond gaps approaching 0.2mm.

The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It also has good oil tolerance to minor surface contaminants.

Ideal for shafts, gears, pulleys and similar cylindrical parts.
