In the competitive landscape of coatings and material science, achieving optimal fire protection is a critical consideration. Antimony Trioxide (ATO), chemically known as Sb2O3 (CAS 1309-64-4), plays a pivotal role as a synergist in flame retardant systems, particularly within paints and coatings formulations. As a dedicated supplier and manufacturer, we focus on providing high-quality ATO to meet these demanding industrial needs.

The effectiveness of Antimony Trioxide in coatings stems from its ability to amplify the performance of halogenated flame retardants. When exposed to fire, ATO undergoes a reaction with halogens present in the coating. This interaction generates antimony halides, which are volatile and interfere with the combustion cycle. They function by scavenging highly reactive free radicals in the gas phase, thereby quenching the flame. This synergistic action significantly reduces the flammability of the coated material.

Beyond its role as a flame retardant synergist, Antimony Trioxide also serves as a valuable pigment and opacifier in paints and coatings. Its inherent white color contributes to the brightness and opacity of the coating, enhancing its aesthetic appeal and coverage. This dual functionality makes it a cost-effective additive for formulators seeking both enhanced fire safety and improved visual properties.

Key applications of Antimony Trioxide in the coatings sector include:

  • Industrial Coatings: For protecting infrastructure, machinery, and equipment where fire resistance is a mandatory safety feature.
  • Architectural Paints: Enhancing the fire safety of interior and exterior building coatings.
  • Specialty Coatings: For applications requiring high levels of fire protection, such as in marine or aerospace industries.
