Poor interfacial bonding between synthetic latex binders and diverse surfaces leads to mechanical failure. Improving adhesion ensures long-term durability and protective integrity of the coating.

The specific combination of styrene, acid monomers, and keto-aldehyde cross-linking addresses the failure of emulsion polymers to maintain internal structural integrity under stress. Improving cohesion prevents adhesive residue and mechanical failure in pressure-sensitive applications.

Inadequate bonding between aqueous polymer binders and non-porous or low-energy surfaces. Improving interfacial strength ensures mechanical integrity and print quality in water-borne systems.
