Ink adhesion promoters are chemical primers that help printing inks stick firmly to substrates, especially difficult or low-surface energy surfaces, by acting as a chemical link between the ink and the surface to prevent peeling or chipping. Boston Industrial Solutions offers ink adhesion promoters for a wide range of surfaces.

An ink adhesion promoter is a chemical pre-treatment used to improve the bond between a printing ink and a substrate. It is a primer that helps inks adhere to the materials they are printed on and improves the durability and reliability of printed graphics.
Ink adhesion promoters are used to help improve ink adhesion to materials such as plastic, glass, metals, coated surface, and low-surface-energy substrates. They create a strong bond that helps prints resist wear, water, and scratching.
An adhesion promoter may be recommended when a printing ink does not achieve the required adhesion to the substrate. It can also be used when printed graphics need improved durability against handling, abrasion, chemicals, or environmental exposure. Follow the guidelines on the technical data sheet of your printing ink to determine which adhesion promoter is required.
Proper surface preparation is important for achieving reliable ink adhesion. Oils, dust, mold-release agents, and other contaminants can interfere with adhesion. Substrates should be properly cleaned and prepared before applying the adhesion promoter.
Not necessarily. Adhesion promoters are formulation- and substrate-dependent, so compatibility should be verified before production by looking at the technical data sheet. The recommended promoter will vary depending on the ink and the material being printed.
