PAINTS & COATINGS
Zinc oxide is used in architectural, industrial and specialty coating systems as a functional additive and pigment stabilizer. It enhances coating durability, UV resistance and formulation stability while contributing to corrosion protection and long-term film performance. Application-specific surface area and controlled particle characteristics allow formulators to balance storage stability, dispersion behavior and coating durability.
Key Requirements
Application-Specific Surface Area (BET)
The specific surface area of zinc oxide influences its interaction with binder systems and overall formulation behavior. Low BET grades support improved storage stability, controlled viscosity and reduced binder demand, while medium BET grades provide increased surface activity for selected functional performance.
UV Stability & Weather Resistance
Zinc oxide contributes to improved UV resistance and long-term durability in coatings exposed to outdoor environments.
Controlled Particle Dispersion
Uniform particle size distribution supports stable dispersion in coating systems, contributing to consistent film formation, opacity and surface finish.
Chemical Stability
ZnO must remain stable within alkaline and resin-based coating systems to ensure predictable formulation behavior and long-term coating performance.
Typical Properties
Zinc Oxide (typically 97–99.9% ZnO) with controlled low and medium BET surface area supports stable dispersion, reduced binder demand and improved coating durability. Designed to provide formulation-specific balance between storage stability, surface activity and long-term coating performance.
