Description

Zinc Oxide Hydrate is a specialized inorganic compound where zinc oxide is chemically associated with water molecules. This material is valued for its unique reactivity and functional properties compared to its anhydrous counterpart, making it a versatile intermediate and functional additive. It is essential for manufacturers in the chemical, pharmaceutical, and personal care industries seeking a controlled source of zinc for synthesis or formulation.

Application

• Rubber Vulcanization: Acts as an activator and reinforcing agent in the production of rubber goods, improving tensile strength and elasticity.
• Cosmetics & Sunscreens: Used as a physical UV filter and opacifying agent in lotions, creams, and makeup formulations.
• Pharmaceuticals: Serves as a source of zinc in mineral supplements and as a mild astringent and protective agent in topical ointments and pastes.
• Ceramics & Glass: Functions as a flux to lower melting temperatures and as a component to modify thermal expansion and optical properties.
• Chemical Synthesis: Employed as a precursor or catalyst in organic reactions and for the preparation of other zinc salts.
• Paints & Coatings: Provides corrosion inhibition, mildew resistance, and UV protection in industrial and marine coatings.

Quality Control

Our Zinc Oxide Hydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for chemical composition, purity, and physical properties. We provide comprehensive Certificates of Analysis (COA) upon request and can tailor quality parameters to meet specific customer requirements, including those aligned with industrial, cosmetic, or pharmaceutical guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture and CO₂.
