This is caused by the anti-adhesive substances contained in the powder which interfere with the establishment of bonding forces between the adhesive and the powder coating. For that reason, researchers have now examined the question of how to address the challenges of adhesive bonding on powder coatings using pressure-sensitive adhesive tapes.
