No-Mix Acrylic Structural Adhesives

No need to mix these acrylics—apply adhesive to one surface and activator to the other, then bring surfaces together to bond. Acrylics bond to the widest range of materials, especially plastics, and require the least amount of surface preparation.

Acrylic Structural Adhesives for Hard-to-Bond Materials

Fasten hard-to-bond plastics, such as polypropylene and polyethylene, with these adhesives. Acrylics bond to the widest range of materials, especially plastics, and require the least amount of surface preparation.

The size listed is the combined total of the two parts. Use a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.

Flexible Light-Activated Instant-Bond Adhesives

These adhesives stay pliable for flexible bonds that resist cracking. For easy positioning, they begin to harden only when exposed to light.

Use adhesives in syringes with a dispensing gun with plunger (sold separately).

Light-Activated Instant-Bond Adhesives

For easy positioning, these adhesives begin to harden only when exposed to light.

Thick liquids fill large gaps and won't drip on vertical surfaces. Thin liquids flow to fill small gaps between close-fitting parts.

Use adhesives in syringes with a dispensing gun with plunger (sold separately).

Retaining Compounds for Close-Fitting Parts

Fill gaps up to 0.01" to secure unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air.

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.

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.

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.

Heavy Duty Light-Activated Coatings for Electronics

Thinner than potting compounds, these coatings flow easily into small spaces between electrical components. They require an ultraviolet curing lamp to reach full strength. Use them to secure and insulate hardware on printed circuit boards.

Syringe coatings require a gun (sold separately) to dispense.
