Benzoic Acid is an additive in various alkyd resin coatings to improve gloss, adhesion, hardness and chemical resistance, a terminator for chain propagation in alkyd resins and promotes crystallinity in the final product. It is an ingredient in water based coatings to get paper free from pinholes and speck formation. To improve finish in synthetic polyester fibre. Incorporation of Benzoic Acid in HDPE filament and thermoplastic elastomers is done to obtain high strength filaments for fishing nets, sportshoes, umbrellas etc. It is used as a vulcanization retardant in rubber.
