About Structural Adhesives

About Paint and Protective Coatings

About Sealant Flexibility

These primers convert rust into a layer of protection that prevents new rust from forming. Use them to prepare your surface to extend the life of paint and coatings.

Apply coatings in a can with a brush, roller, or sprayer.

Primers for Instant-Bond Adhesives

Improve instant-bond adhesive performance on hard-to-bond slippery plastics. These primers cannot be sold to the regions listed because they exceed local regulatory limits on VOCs (volatile organic compounds).

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

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.

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.

Heavy Duty Threadlockers

To withstand demanding, high-vibration applications such as motor and pump housings, these threadlockers have high breakaway torque. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Adjustable Threadlockers

These threadlockers give a secure hold, but can be easily adjusted with hand tools. They can be removed without damaging countersunk fasteners, set screws, and other small fasteners. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

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 medium locking strength require a hand tool to unthread.

Threadlockers

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.

Thin Film and Label Application Primers

4 oz.

32 oz.

Smoothing Tool

Spray these primers onto a mounting surface to quickly and smoothly apply signs, labels, and protective films. These primers float adhesive-backed sheets above a surface until you press them down, giving you time to position the sheet and remove any wrinkles. Since the sheet doesn’t stick right away, you can apply large sheets without needing a second pair of hands. These primers also work with non-adhesive films. Even in hot or cold temperatures, your sheet will stay put.

Clean the mounting surface with primer before applying a film, so no residue is trapped underneath. Use a smoothing tool (sold separately) to squeeze out air bubbles and excess fluid. Drying time depends on application—most decals and films will dry within 90 seconds, but 3D printer sheets should dry for 24 hours before printing.
