Bonding Agents

McCoy offers Bonding Agents, Ultrabond 821. It is for cylindrical bonding. It improves machine reliability by strengthening the shaft and sleeve assembly. It lowers cost with scope for wider machining tolerances. It fills the microscopic voids that are inherently present in even the best inference fits and hardens to strengthen the assembly. The metal cement undergo anaerobic (absence of oxygen) curing when confined between mating metal surfaces. Apart from anaerobic curing, it offers added flexibility by curing when exposed to ultraviolet light. It enhances the performance of mechanical retaining methods such as splines, keyways, setscrews and inference fits. Benefits: seals internal surfaces and prevents fretting corrosions; distributes loading and prevents stress concentration even in the assembly of dissimilar material; easy alignment or assembly with wider fitting tolerances; high chemical and temperature resistance; and easy to apply and clean, no mixing required. Typical applications: pins and keyways; bearings; brushing and sleeves; gears, pulleys and sprockets; rotors and flywheels; and brazed and soldered joints.
