Adhesion Mechanisms of Water-Based Polymers on Mineral Substrates

Abstract

Reliable adhesion to mineral substrates such as concrete, mortar, and masonry is a fundamental requirement for construction polymers. This white paper examines adhesion mechanisms of water-based polymer systems and the structural factors influencing bond durability.

Challenges of Mineral Substrates

Mineral surfaces are inherently alkaline, porous, and heterogeneous. Moisture movement and surface contamination further complicate adhesion, particularly for water-based systems.

Molecular-Level Adhesion Design

Ruico enhances adhesion through:

• Introduction of polar functional groups capable of hydrogen bonding and ionic interaction

• Optimized particle deformability to improve surface wetting

• Controlled molecular weight distribution for interfacial penetration

These mechanisms create both physical anchoring and chemical interaction at the interface.

Long-Term Adhesion Retention

Adhesion durability depends on resistance to hydrolysis, moisture cycling, and alkaline degradation. Polymer backbones and interfacial chemistry are designed to maintain bonding strength over extended service life.

Construction Applications

• Concrete primers and sealers

• Polymer-modified mortars

• Structural adhesives and coatings

Conclusion

Adhesion is a system-level property governed by polymer chemistry, morphology, and substrate interaction, requiring deliberate molecular design.
