Waterborne Coatings
Well-T’s colloidal silica enhances adhesion, film formation, and long-term durability across water-based, silicate, and nano-ceramic coating systems.
Built around real formulation and application needs, our portfolio includes silane-, cationic-, and aluminum-modified grades, as well as large-particle solutions to support various coating applications.
Key Advantages
Stronger Compatibility and Adhesion
Surface-functionalized grades improve interaction with emulsions and resins, enhancing adhesion, water resistance, and weatherability.
Thicker Films, Less Cracking
Large-particle colloidal silica supports thicker film formation with lower shrinkage, improving wear resistance and coating life.
Reliable High-Temperature Performance
Aluminum-modified grades maintain stable dispersion and form a dense inorganic network for improved heat and corrosion resistance.
Better Adhesion to Anionic Surfaces
Cationic colloidal silica bonds effectively with negatively charged substrates, improving coating uniformity and adhesion.
