Zinc Powder
- Powder type
Zinc powder is a metallic zinc powder, characteristically gray in color and appearing as spherical metallic dust particles. Standard-grade zinc powder features a slightly oxidized surface, which enhances storage stability, improves dispersibility during application, and prevents clumping. For specialized applications, premium-grade zinc powder with superior fineness (finer particle size) is also available.
