Zinc borate is widely used as a flame retardant in various materials such as plastics, rubber, and textiles. It works by releasing water when exposed to heat, which helps to suppress flames and reduce smoke production. Additionally, it is utilized in wood products to enhance their fire resistance. In the ceramics industry, it acts as a flux to lower the melting temperature and improve the quality of the final product. It is also employed in coatings and paints to provide corrosion resistance and improve durability. Furthermore, zinc borate finds application in adhesives and sealants to enhance their fire-retardant properties.
