Frequently asked

Why is a primer used before structural bonding?

A bond primer protects the prepared surface until bonding and helps the durability of the adhesive joint, particularly in humid service.

Is the primer matched to a particular adhesive?

Yes. Use the primer and adhesive combination named on 3M's data sheet or in your bonding process specification.
