Adhesion promoters improve direct-to-metal adhesion in water-borne and solvent-borne coatings, primers and inks through the formation of a direct bond with the metal, which also improves coating flexibility and corrosion resistance through the same mechanism. can also deliver the added benefits of passivation and intercoat adhesion, and can even e adhesion to poorly prepared substrates.
Lubrizol is a recognized leader in chemistry for metal protection because of our commitment to collaboration, ability to deliver value and a focus on innovation to continuously meet customer needs. We offer a number of adhesion promoter technologies from the pretreatment to refinish stages of the product life cycle.
Lubrizol adhesion promoters are phosphate ester and hydroxyl functional polymers that improve adhesion of water-borne and solvent-borne coatings and inks to ferrous metal, zinc alloy and aluminum substrates—without adversely affecting storage stability. These performance adhesion additives can also be used for stabilizing aluminum and other metallic effect pigments in water-borne systems, especially for the prevention of gassing and corrosion.
Typical Applications
Proven in a variety of applications, particularly automotive and industrial metal finishes, Lubrizol adhesion additives are used in direct-to-metal coatings and primer formulations for a number of applications, including:
- Automotive OEM and VR Coatings
- Can Coatings
- Coil Coatings
