Adhesion Promoter
An adhesion promoter is an additive or surface-treatment chemistry that improves bonding between materials that otherwise may not adhere strongly. It can work by increasing surface compatibility, creating chemical bridges, improving wetting, or strengthening the interface between a coating, adhesive, resin, film, or substrate.
