Applications
- Rubber & Tire Industry: Acts as a crucial vulcanization activator and reinforcing agent. It improves the thermal conductivity, wear resistance, and anti-aging properties of rubber products.
- Coatings & Paints: Used as a high-quality inorganic white pigment. It provides excellent hiding power, anti-corrosion properties, and acts as a mold inhibitor and UV stabilizer.
- Cosmetics & Sunscreens: Especially in Nano form, it serves as a broad-spectrum physical UV filter (UVA/UVB), providing high transparency and non-irritating protection.
- Ceramics & Glass: Functions as a fluxing agent to reduce the melting temperature and enhance the gloss and durability of ceramic glazes.
- Electronics: Used in the production of varistors, thermistors, and image recording materials due to its unique semiconducting properties.
- Agriculture: Applied as a zinc micronutrient in fertilizers and animal feed additives to promote growth and health.
Storage Conditions
- Environment: Store in a cool, dry, and well-ventilated warehouse.
- Moisture Protection: Keep containers tightly closed to prevent moisture absorption and clumping.
- Segregation: Store away from strong acids, strong bases, and edible chemical raw materials.
- Shelf Life: 24 months from the date of manufacture if stored in original, unopened packaging.
Safety Precautions
- Handling: Avoid dust formation. Use local exhaust ventilation or wear appropriate dust masks (N95/P2) during handling to avoid inhalation.
- Personal Protection: Wear safety goggles and protective gloves to prevent skin and eye irritation.
- Ingestion: Do not eat, drink, or smoke in the workplace. Wash hands thoroughly after handling.
- Environmental: Prevent large quantities of the product from entering sewage systems or water sources. Zinc oxide is classified as toxic to aquatic life with long-lasting effects.
