IOTA Si69 not only performs exceptionally well in rubber but also shines in the modification of inorganic fillers. For materials rich in hydroxyl groups on their surface, such as silica, talc, mica, and glass fiber, it can form an organically compatible layer through silane bonding, thereby improving compatibility with resins or rubber.

Fillers treated with IOTA Si69 exhibit better dispersibility and are less prone to agglomeration; simultaneously, their bonding strength with the organic matrix is enhanced, resulting in composite materials with higher strength, better wear resistance, and better water resistance. For example, in vulcanized rubber, it enables carbon black and silica to work synergistically, achieving more balanced dynamic properties.

Furthermore, IOTA Si69 can be used in glass fiber reinforced rubber or resin systems to improve interfacial adhesion and reduce mechanical degradation caused by interfacial delamination.

This structure, combining coupling and vulcanization functions, makes IOTA Si69 a versatile additive in the field of material modification, widely used in industries such as tires, footwear, cables, rubber rollers, and composite materials.
