Description

Industrial Grade Zinc Oxide Supplier — Rubber, Ceramic & Paint Applications | Davar ChemTech

Zinc oxide (ZnO) is a versatile inorganic compound that occupies a critical position across multiple industrial sectors, functioning simultaneously as an activator in rubber vulcanization, a UV-blocking pigment in paints and coatings, a fluxing agent in ceramic glazes, and a key raw material in pharmaceutical and personal care formulations. Its unique combination of high refractive index, thermal stability, chemical inertness, and antibacterial properties makes it one of the most widely consumed specialty chemicals in India’s manufacturing landscape. For procurement teams managing multi-product supply chains across rubber, ceramics, paint, and pharmaceutical industries, securing a zinc oxide supplier who can deliver consistent particle size, controlled lead and cadmium content, and reliable packaging is essential for maintaining product quality and regulatory compliance across diverse end-use applications.

Key Technical Features

• French process and American process grades available, covering specific surface area from 2-10 m2/g for application-specific performance
• Tight control on heavy metal impurities — lead content below 50 ppm, cadmium below 20 ppm — meeting pharmaceutical and food-contact requirements
• High purity (99.0-99.9% ZnO) with consistent particle size distribution ensuring reproducible processing characteristics batch after batch
• Excellent dispersion characteristics in rubber compounds, paint formulations, and ceramic slurries, reducing processing time and improving end-product uniformity
• Multiple packaging options — 25 kg PP bags, 50 kg HDPE drums, and 500 kg jumbo bags — tailored to customer consumption volumes

Industrial Applications

The rubber industry is the largest single consumer of zinc oxide in India, where it serves as an essential activator in the sulfur vulcanization process for both natural rubber (NR) and synthetic rubber (SBR, NBR, EPDM) compounds. Without adequate zinc oxide, vulcanization kinetics become sluggish and incomplete, resulting in under-cured products with inferior tensile strength, elongation, and aging resistance. Tire manufacturers, conveyor belt producers, automotive rubber component suppliers, and footwear manufacturing units across India depend on consistent zinc oxide quality to achieve target cure characteristics in their compounds. The ceramics and glass industry utilizes zinc oxide as a fluxing agent and opacifier in glazes, frits, and glass formulations — its ability to lower melting temperatures while improving gloss and thermal expansion matching makes it indispensable in wall tile, sanitaryware, and tableware production clusters located in Gujarat, Rajasthan, and Morbi. In the paints and coatings sector, zinc oxide functions as a UV-absorbing pigment in exterior paints, a mildewcide in architectural coatings, and a corrosion-inhibiting component in galvanized metal primers. The pharmaceutical industry employs pharmaceutical-grade zinc oxide in sunscreen formulations, antiseptic creams, diaper rash ointments, and zinc supplements, where purity and particle morphology directly influence product efficacy and regulatory compliance.

Storage, Handling & Safety

Zinc oxide powder should be stored in its original moisture-proof packaging in a dry, well-ventilated warehouse area away from acidic or ammonium-containing substances that can react with ZnO to form undesirable zinc compounds. Storage areas should maintain humidity below 70% and temperature below 40 degrees Celsius to prevent moisture absorption and caking. Workers handling zinc oxide powder must wear NIOSH-approved dust masks or respirators, chemical-resistant gloves, and safety goggles to prevent inhalation and eye contact. Prolonged inhalation of zinc oxide fumes or dust can cause metal fume fever — a flu-like condition characterized by chills, fever, muscle aches, and fatigue that typically resolves within 24-48 hours. Occupational exposure limits should be maintained below 5 mg/m3 as an 8-hour TWA. Spills should be collected using vacuum systems equipped with HEPA filters rather than dry sweeping to minimize airborne dust generation.

Supply Capability & Distribution

From our Vadodara distribution center, Davar ChemTech supplies zinc oxide to rubber compounders in Gujarat’s automotive component corridor, ceramic manufacturers in Morbi and Thangadh, paint producers in Mumbai and Chennai, and pharmaceutical companies across western and central India. Our warehousing infrastructure includes dedicated dry-storage zones with humidity monitoring, ensuring that powder products remain free-flowing and contamination-free throughout the storage period. We maintain inventory of multiple grades simultaneously — rubber grade, ceramic grade, paint grade, and pharmaceutical grade — enabling mixed-grade procurement from a single source with consolidated delivery scheduling. Our logistics partners specialize in handling dry bulk chemicals and provide covered transport to prevent moisture exposure during transit.

Quality Assurance & Trust

Every zinc oxide shipment from Davar ChemTech is accompanied by a certificate of analysis that documents ZnO purity, loss on ignition, lead content, cadmium content, moisture, and particle size parameters. We source from ISO 9001-certified manufacturers who employ both the French process (indirect method) and American process (direct method), and we maintain traceability records that enable full batch tracking from receipt through dispatch. Our clients — from tire plants to pharmaceutical units — rely on this consistent quality documentation to support their own regulatory compliance and customer certification requirements.
