AST-SEAL 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-SEAL Anaerobic Threadlockers provide a solution for every practical industrial application. Seal hairline weld fracture. Seal standard and stainless steel pipe for the life of the connection. Use right out of the bottle. Packaged in three popular sizes to fit your particular job or application.
AST-SEAL™ 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 even tougher applications and harsh environments. It is excellent for use when sealing inactive metallic surfaces such as stainless steel or galvanized pipe.
