Key silicone products for the textile finishing value chain

Epoxy double sealing agent

Epoxy double sealing agent is key raw material to produce end-epoxy silicone oil. Through reaction of epoxy groups at both ends with active groups on polymer chain, effective bonding between organic materials and inorganic fillers (such as glass fiber, mineral fillers) is achieved, thereby improving mechanical properties, electrical insulation properties and heat resistance of composite materials.
