What is an adherence promoter or adhesion?
An adhesion promoter in inks is a chemical additive used to improve the bond between the ink and the substrate or surface to which it is applied. It increases the ink’s ability to adhere to the substrate, ensuring better ink coverage, durability, and resistance to rubbing or smudging.
Adhesion promoters work by altering the surface properties of the substrate, creating a more favorable environment for ink adhesion. They typically contain compounds that promote wetting, increase surface energy, or provide chemical interactions with both the ink and the substrate.
How do we apply it to inks?
Inks are commonly applied to a wide range of materials, including plastics, metals, glass, ceramics, and other substrates. However, different materials have varying surface properties, and some substrates can be inherently difficult to adhere to due to their low surface energy or other factors. Adhesion promoters help overcome these challenges by improving the interactions between the ink and the substrate, thus promoting stronger adhesion.
HUBERGROUP UAP-11002 Membership Promoter
HUBERGROUP‘s UAP-11002 is a stable, TAA-free, organic titanium complex in 2-propanol. It exhibits good compatibility with NC, polyurethanes, polyamides, maleic resins, and other binder systems. It can be used in inks to improve the adhesion of solvent-based flexographic or gravure inks to various substrates, such as OPP, PET, metal, etc.

By using adhesion promoters in inks, manufacturers can achieve better print quality, improved adhesion, and greater durability, ultimately improving the overall performance of printed materials.
