Zinc Borate is a boron-based fungicide and fire retardant with a chemical composition of ZnOB2O3H2O. The most commonly used grade have following structure 2ZnO.3B2O3zH2.3,5H2O Its optimum performance is as a Biocide (fungicide and preservative) and corrosion inhibitor and this is obtained when our product is uniformly dispersed in a coating or composite. With a coating it should be incorporated during the pigment dispersion cycle in the coating preparation process. Zinc Borate can be used as a fire retardant in PVC, Polyolefins, Elastomers, Polyamides, Epoxy resins. In halogen-containing systems, Zinc Borate is used in conjunction with antimony oxide, while in halogen-free systems, it is normally used in conjunction with alumina trihydrate, magnesium hydroxide, or red phosphorus. In some particular applications Zinc Borate can be used alone. Royce Zinc Borate is EPA approved.
