Description

Lead Silicochromate is an inorganic pigment and corrosion inhibitor primarily composed of lead chromate and silica. This compound is valued for its excellent anti-corrosive properties and vibrant color, making it a key component in protective coatings. It is essential for manufacturers in the heavy-duty industrial coatings, primers, and marine paint sectors who require durable, long-lasting protection for metal substrates exposed to harsh environments.

Application

• Anti-Corrosive Primers: A critical pigment in primers for steel structures, bridges, ship hulls, and industrial equipment to prevent rust and degradation.
• Heavy-Duty Industrial Coatings: Used in coatings for chemical plants, oil rigs, pipelines, and other infrastructure requiring maximum corrosion resistance.
• Marine and Offshore Paints: Formulated into paints that protect vessels and offshore platforms from saltwater corrosion and fouling.
• Automotive Underbody Coatings: Provides protective layers for vehicle undercarriages exposed to road salts, water, and debris.
• Traffic and Safety Marking Paints: Imparts color and durability to road marking paints, enhancing visibility and longevity.
• Pigment for Plastics and Masterbatches: Used as a coloring and stabilizing agent in specific plastic and polymer applications.

Quality Control

Our Lead Silicochromate is manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through rigorous testing for key parameters such as chromate content, silica ratio, particle size distribution, and color strength. While this is an industrial-grade product, we adhere to relevant industry standards for pigments and corrosion inhibitors. A Certificate of Analysis (COA) detailing specific test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Keep container tightly sealed when not in use to prevent moisture absorption and contamination. Recommended storage temperature is 15-25°C.
