Description

Flake White CAS NO 54392-33-5 is a high-purity, synthetic inorganic pigment primarily composed of basic lead carbonate. This compound is valued for its exceptional opacity, brilliant white color, and excellent covering power in various formulations. It is a critical raw material for manufacturers in the coatings, plastics, and specialty chemical industries seeking consistent quality and performance. Reliable sourcing of this material is essential for producing durable finishes and composite materials.

Application

• Pigment for Industrial Coatings & Paints: Used as a prime white pigment in corrosion-resistant primers, marine paints, and industrial finishes for its density and opacity.
• Plastics & Polymer Masterbatches: Acts as a whitening and opacifying agent in PVC, polyolefins, and engineering plastics to enhance brightness and UV reflectivity.
• Specialty Inks & Printing: Employed in high-quality printing inks where superior hiding power and a clean white base are required.
• Ceramic Glazes & Frits: Serves as a component in ceramic formulations to achieve specific white tones and surface properties.
• Artists' & Restoration Materials: Used in the production of high-grade artists' oil paints and materials for historical restoration work.
• Stabilizer & Filler Compositions: Functions in certain niche applications as a stabilizer or high-density filler in composite materials.

Quality Control

Our Flake White is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical tests, including assay, heavy metal limits, and physical property assessments. While this product is typically supplied to industrial grade specifications, we adhere to rigorous internal standards for particle size distribution and chemical composition. Certificates of Analysis (COA) documenting key parameters are available upon request for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep the container securely sealed when not in use to minimize exposure to atmospheric carbon dioxide and moisture. Store away from incompatible materials such as strong acids.
