1. Paints, Coatings & Adhesives

• Synergist: Antimony tribromide (SbBr3) is primarily used as a fire retardant synergist in combination with halogenated materials in paints, coatings, and adhesives. It enhances the fire-retardant properties of these materials by reacting with halogens to create a vapor that smothers flames.

2. Polymers & Resins

• Fire Retardant: Antimony tribromide acts as a synergist with halogen-containing polymers, meaning it enhances the flame-retardant properties of these materials. This is a common application in plastics and other polymer-based products where fire safety is a concern.

3. Performance Chemicals

• Brominating Agent: Antimony tribromide is been used to introduce bromine atoms into organic molecules, such as in the bromination of p-nitrotoluene to produce p-nitrobenzyl bromide. It acts as a source of electrophilic bromine, which is essential for this type of reaction.
• Catalyst: Antimony tribromide act as a catalyst in various chemical reactions. For example, it can be used in conjunction with other catalysts, like ferric bromide, to influence the outcome of bromination reactions.
• Chemical Analysis: Antimony tribromide is used in chemical analysis as a reagent or a component in analytical procedures.

4. Lubricants & Automobiles

• Precursor: It is primarily used as a precursor to create other antimony compounds, such as antimony dithiocarbamates, which are known to enhance the extreme pressure (EP) and anti-wear properties of lubricating oils and greases.
