About Structural Adhesives

About Sealant Flexibility

Prevent threaded fasteners from loosening due to shock and vibration. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked. Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes; and cadmium and zinc coatings.

Threadlockers with medium locking strength require a hand tool to unthread.

Threadlockers with high locking strength require both heat and a hand tool to unthread.

2432 works especially well on stainless steel and titanium. It's suitable for use in nuclear applications.

High-Temperature Threadlockers

Keep threaded fasteners from loosening at temperatures up to 450° F. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Threadlockers with medium locking strength require a hand tool to unthread.

Thread Sealants

These thread sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.

Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.

Thread Sealants with PTFE

PTFE provides a slippery surface that keeps threads from binding. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.

Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

Thread Sealants for Hydraulic and Compressed Air Systems

Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air. VOC (Volatile Organic Compounds) regulations restrict sales to the listed jurisdictions/areas.

Sealants with medium locking strength prevent threads from loosening due to vibration and shock. They require a hand tool to unthread.

Thread Sealants for Refrigeration Systems

For use in refrigeration systems and applications exposed to strong chemicals, these sealants have excellent solvent resistance. They’re anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.
