3M™ VHB™ Tape Primer

Choose the Right Primer for Your Surface

For some challenging substrates, a primer or adhesion promoter may improve the reliability of the bond. Consult with IDP Technical Service to determine if a surface preparation step will be required for your application.

How to Prepare Specific Surfaces

  • HEAVY OILS - remove oil or grease using a degreaser or solvent-based cleaner.
  • ABRASION – Abrade the surface to remove heavy dirt or oxidation.
  • HIGHER ADHESION – Prime surfaces to increase adhesion – especially for paint or plastic surfaces.
  • POROUS SURFACES – Seal surfaces such as wood, particle board or concrete.
  • GLASS – Use silane treatment.
  • OTHER MATERIALS – Consider the potential for special surface preparation for all materials, including metal, copper, plastics, rubber, and more.
