Applications of Non-Spherical Colloidal Silica
Non-spherical silica particles can form interconnected structures during film formation. Grade selection should consider particle shape, DLS length, TEM diameter, silica content and formulation pH.
Film-Forming Coatings
Branched particles can interconnect during drying and support film formation in compatible coating systems.
Superhydrophilic Coatings
Evaluated for creating microscopic surface roughness in formulations designed for high wettability.
Superhydrophobic Coatings
Used in compatible surface-structure designs where branched silica contributes controlled micro-roughness.
Functional Glass Coatings
Applied in glass-coating development intended to improve light transmission and add self-cleaning properties.
Self-Cleaning Surfaces
Supports surface-treatment trials combining non-spherical particles with compatible coating chemistries.
Specialty Surface Modification
Suitable for development projects requiring branched or potato-shaped silica with defined particle dimensions.
