1.Antimony trioxide for fire-resistant coating Reduces toxic smoke and fumes compared to some phosphorus-based retardants, improving safety in enclosed spaces.
2.Antimony trioxide for fire-resistant coating Promotes a protective char layer that insulates the underlying material, delaying structural damage during fires.
3.Antimony trioxide for fire-resistant coating Works effectively with halogenated resins (e.g., chlorinated rubber, PVC-based coatings) to significantly suppress combustion.
1. Introduction
Antimony trioxide (Sb₂O₃) is a highly effective flame-retardant synergist widely used in fireproof coatings to enhance fire resistance across various construction materials. When combined with halogenated compounds, it significantly improves the thermal barrier properties of coatings while maintaining their structural integrity.
2. Antimony Trioxide in Fire-Resistant Coatings: Mechanism and Benefits
2.1 Flame Retardant Mechanism
Sb₂O₃ works synergistically with halogenated resins (e.g., chlorinated rubber, epoxy, or acrylic binders) to:
Form antimony halides during combustion, which interrupt free radical chain reactions.
Promote char layer formation, slowing heat transfer and protecting the substrate.
Reduce smoke and toxic gas emissions, enhancing safety in enclosed spaces.
2.2 Key Advantages in Fireproof Coatings
√ High thermal stability (effective up to 600°C+)
√ Low smoke emission (critical for tunnels and indoor applications)
√ Cost-effective compared to intumescent or non-halogenated alternatives
√ Minimal impact on coating adhesion and flexibility
