Ink Adhesion Promoter
CAS Number: 13822-56-5
A titanate-based coupling agent that acts as a molecular bridge between ink resins and difficult-to-bond substrates such as polyolefins, aluminum foil, and metalized films. It improves wet and dry adhesion, reduces delamination risk, and enhances chemical resistance of the printed film. Particularly effective for solvent-free UV-curable and waterborne ink systems applied to non-porous substrates.
