Zinc Oxide

Product Overview

Zinc Oxide (ZnO) from 20 Microns is a versatile inorganic compound engineered for use across coatings, rubber, ceramics, and adhesive industries. With a high level of purity, fine particle size, and excellent chemical stability, it serves as a multi-functional additive that enhances protection, performance, and durability in end applications.

In coatings and paints, Zinc Oxide functions as an inorganic pigment providing corrosion inhibition, mildew resistance, gloss maintenance, and TiO₂ extension. Its ability to block UV radiation and resist microbial growth ensures long-lasting performance even in harsh environments.

In rubber and adhesive systems, Zinc Oxide acts as a vulcanizing agent and activator, improving adhesion strength, mechanical properties, and heat resistance.

Key Benefits

• Corrosion Inhibition - Protects metallic surfaces from oxidation and environmental degradation.
• Mildew & Microbial Resistance - Prevents fungal and bacterial growth on coated surfaces.
• Excellent Coverage & Gloss Retention - Maintains film uniformity and visual appeal over time.
• TiO₂ Extension - Functions as a cost-effective extender without affecting opacity or brightness.
• Improved Adhesion & Durability - Enhances inter-coat bonding and coating lifespan.
• Thermal Stability - Provides heat resistance and mechanical strength in rubber compounds.
