What Is Adhesive Primer?
Adhesive primer is a preparatory treatment used to enhance the adhesive strength of adhesives.
Functioning through a blend of solvents, resins, additives, and other constituents, its operation principle involves dissolving the material surface, creating surface roughness, and expanding the contact area with the adhesive. Moreover, the resin component fosters adhesion with the adhesive, thereby bolstering adhesive strength.
Adhesive primers are used extensively on materials like plastics, metals, and rubbers. For these substrates, surface treatment is conducted, followed by applying adhesive primer, which is allowed to dry before applying the adhesive for bonding. Noteworthy features of adhesive primer encompass enhanced adhesive strength, excellent workability, compatibility with diverse materials, and adjustable drying time.
