About Sealant Flexibility

About Structural Adhesives

About Paint and Protective Coatings

Add long-term corrosion protection to uncoated or rusty metal surfaces. These primers prepare your surface to extend the life of paint and coatings. Apply with a brush, roller, or sprayer.

Acrylic primers are available in two colors. Choose gray primer for light-colored topcoats; red for dark topcoats.

Polyurethane primers can be applied in environments with high humidity or extreme temperatures. Surface must be visibly dry and free of frost and ice.

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.
