AST-Lock™ 20RC - High Temperature, High Viscosity is specifically engineered to meet close tolerance and high temperature requirements. Maximum gap-filling ability makes this retaining compound the perfect choice for loosely fitted parts. Use a primer on gaps over .005”.

AST-LOCK anaerobics cure within metal connections, in the absence of oxygen, and at ambient temperatures. Available in a full range of strengths and viscosities. These anaerobics fill all surface imperfections and set to a tough, durable seal across the entire surface while distributing the stress load and reducing fastener fatigue. Vibration loosening is prevented and the connection is sealed and protected against corrosion.

AST-LOCK Retaining Compounds provide a solution for every practical industrial application. Retain bearings and housings and reduce maintenance for pneumatic/hydraulic equipment. Use right out of the bottle. Packaged in three popular sizes to fit your particular job or application.

AST-LOCK™ anaerobics are single-component, fast-curing, and solvent-free. Eliminates the need for other mechanical locking devices. Hardening only within the joint, anaerobics do not block or contaminate the system; excess resin outside remains in liquid state and is removed easily. Improve products quality and reliability.

For use with most AST-SEAL™ anaerobic compounds :

AST-LOCK™ PRIMER T is Heptane Based and fast acting Viscosity : 3 Cps, Flash Point : 0°F, Color : Green.

AST-LOCK™ PRIMER N is Heptane Based and good for general-purpose applications Viscosity : 3 Cps, Flash Point : 30°F, Color : Green.

Designed for augmenting the strength of press-fitted assemblies and can be used on slip-fitted parts with a diametrical clearance of up to 0.005". Should be used on new and replacement parts.
