Bonding primer for industrial adhesive tape

      Description of industrial uses

Primer is a coating that is applied on the surface to bond and that improves the bonding of adhesive tape on the surface concerned by improving the surface energy.

Primer is applied with a brush or our primer applicator (see video below). Primer is generally a volatile product : it is necessary to reseal the container after each use. It is also important to read the technical data sheet and the safety data sheet attentively, and if necessary to wear a suitable mask during the application.

There are primers available for each surface : For glass, for rubber, for steel, for wood, for plastic (PP and EPDM) for Epoxy powder coating…

The primer application does not replace cleaning and surface preparation.

      Some tips for choosing primer ?

• For the application, make sure the surface is clean, dry and degreased before applying the primer.
• For porous material, a second coat might be necessary, and for PP and EPDM, you can use reference K500 from the company 3M.
• Adezif also offers a wide range of Bonderite products (Henkel group), including high-quality adhesion promoters and coatings specifically designed for metal surfaces (automotive, aeronautics, electronics...).
• Wait until the primer is completely dry before applying the adhesive tape.
• When choosing a primer, it is important to ensure it is compatible with the selected adhesive.
