Used primarily as a coupling agent in the production of composites and adhesives, it enhances the bond between organic polymers and inorganic materials. It is also applied in surface treatment of fillers and pigments to improve their compatibility with polymer matrices. In the coatings industry, it serves to increase adhesion to various substrates, ensuring durability and resistance to environmental factors. Additionally, it is utilized in the modification of silica-based materials for better performance in rubber and plastic applications. Its role in crosslinking and improving mechanical properties makes it valuable in sealants and elastomers.
