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.
Primers for Structural Adhesives
Use these primers with structural epoxies, acrylics, and urethanes to promote bonding to EPDM rubber, polyolefin, and thermoplastic elastomers. They cannot be sold to the regions listed due to local regulatory limits on VOC (volatile organic compounds).

Adhesive Accelerators for Instant-Bond Adhesives
Shorten the time it takes instant-bond adhesives to reach full strength. Apply these accelerators before bonding with instant-bond adhesives for strength, or after bonding to keep adhesive from turning cloudy.
Bottles of Scotch-Weld 87937, 712, 7109, and 7113 include both a brush and spray head for easy dispensing.
Scotch-Weld 87937 also works as a primer on porous materials.

Thin Film and Label Application Primers
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.
