In the realm of coatings and paints, achieving enhanced fire resistance and long-term durability is a constant challenge for formulators. Zinc Borate (CAS 1332-07-6) stands out as a versatile inorganic additive that plays a crucial role in meeting these demands, particularly in intumescent coatings and other fire-protective systems. As a leading Zinc Borate manufacturer, we provide high-quality materials that empower coating producers to develop advanced, safer products. If you are looking to purchase Zinc Borate, this guide offers valuable insights.

The Multifaceted Benefits of Zinc Borate in Coatings

Zinc Borate contributes to the performance of coatings through several key mechanisms:

  • Intumescent System Activation: In intumescent coatings, Zinc Borate acts as a synergist. When exposed to heat, it helps to promote the formation of a stable, insulating char layer. This char expands significantly, creating a barrier that protects the underlying substrate from heat and flames. It works in conjunction with intumescent agents like carbonific, dehydrating, and blowing agents.
  • Flame Retardancy: Beyond intumescent systems, Zinc Borate can be incorporated into various coating formulations to impart general flame retardancy, reducing the flammability of the coated material.
  • Smoke Suppression: Similar to its performance in polymers, Zinc Borate helps to reduce smoke generation during combustion, which is a critical safety feature for architectural coatings and materials used in confined spaces.
  • Improved Durability and Weathering: The inorganic nature of Zinc Borate can also contribute to the overall durability and weather resistance of coatings, enhancing their lifespan.
  • Fungicidal and Mildew Inhibiting Properties: Historically, borates have also been recognized for their fungicidal and mildew inhibiting properties, adding another layer of protection, especially in exterior coatings or humid environments.
