Description

Aluminium Dihydrogen Tripolyphosphate is an inorganic salt widely utilized as a high-performance corrosion inhibitor and flame retardant synergist. Its value lies in its ability to form stable, protective layers on metal surfaces and enhance the fire resistance of various polymer matrices. This compound is essential for manufacturers in the coatings, plastics, construction materials, and metal treatment industries seeking to improve product durability and safety.

Application

• Anticorrosive Pigments: A key component in primers and coatings for steel, aluminum, and other metals, providing long-term protection against rust and corrosion.
• Flame Retardant Synergist: Used in conjunction with other flame retardants in plastics, rubber, and textiles to significantly improve fire resistance and reduce smoke emission.
• Metal Pretreatment: Applied in conversion coatings and surface treatment processes to prepare metals for painting or powder coating, enhancing adhesion.
• Construction Materials: Incorporated into fire-resistant boards, sealants, and intumescent paints for structural fire protection.
• Lubricant & Grease Additive: Functions as an anti-wear and extreme pressure additive in specialized industrial lubricants.
• Ceramic & Glass Processing: Acts as a fluxing agent and stabilizer in certain ceramic glazes and specialty glass formulations.

Quality Control

Our Aluminium Dihydrogen Tripolyphosphate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, particle size distribution, and performance characteristics. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
