About Structural Adhesives

Acrylic Structural 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.

H8000 and H8100 maintain their impact resistance at cold temperatures.

Light-Activated Instant-Bond Adhesives

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

Thin liquids flow to fill small gaps between close-fitting parts.

Wicking Threadlockers

Apply these threadlockers on fasteners that are already installed—their thin consistency allows them to flow into small gaps. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

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

High-Temperature Wicking Threadlockers

These threadlockers withstand temperatures up to 450° F. The thin consistency allows them to flow into small gaps, so you can apply them on fasteners that are already installed. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Primers for Threadlockers, Retaining Compounds, and Acrylic Adhesives

To speed cure time on coated fasteners, aluminum, stainless steel, or titanium, apply these primers before using threadlocker or retaining compound. They also work with no-mix acrylic adhesives.

Primers in brush-top bottles also include a spray head for easy dispensing.

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.

Retaining Compounds for Oily Close-Fitting Parts

Even on oily surfaces, these retaining compounds keep their hold. Use them to fill gaps up to 0.015" to secure worn 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.

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

Heavy Duty High-Purity Light-Activated Coatings for Electronics

This coating is formulated for use in sensitive applications such as manufacturing semiconductors. Thinner than potting compounds, it flows easily into small spaces between electrical components. The coating begins to harden when exposed to UV light. Use it to secure and insulate hardware on printed circuit boards. It requires a gun (sold separately) to dispense.
