Description

Glycerol Borate is an organoboron compound formed by the esterification of glycerol with boric acid. This versatile chemical intermediate is valued for its ability to act as a source of both boron and glycerol in controlled-release formulations and as a cross-linking agent. It serves critical functions in industries ranging from polymer manufacturing to specialty chemical synthesis, where its unique reactivity profile is essential.

Application

• Polymer & Resin Industry: Used as a cross-linking agent and modifier in the production of epoxy resins, polyurethanes, and phenolic resins to enhance thermal stability and mechanical properties.
• Flame Retardant Formulations: Acts as a synergistic component in halogen-free flame retardant systems for plastics, textiles, and coatings.
• Wood Treatment & Preservation: Employed in formulations to impart fire resistance and fungal/insect protection to timber and engineered wood products.
• Lubricant & Grease Additive: Functions as an anti-wear and extreme pressure (EP) additive in synthetic lubricants and metalworking fluids.
• Ceramic & Glass Production: Serves as a fluxing agent and boron source to lower melting temperatures and modify the properties of glasses and ceramic glazes.
• Adhesive & Sealant Systems: Utilized as a tackifier and curing agent in specialty adhesive formulations to improve bond strength and environmental resistance.
