Synthetic inorganic-organic hybrid chemicals make up silane coupling agents. They are applied to create a strong connection between organic and inorganic substances. Silane coupling agents are used for a number of activities, such as surface treatment of glass fibre goods, improved performance of fiber-reinforced plastics by direct mixing to synthetic resin, enhancement of paints and other coating materials and adhesives, change of the surface characteristics of filler particles, or surface priming of various material surfaces. Colorless, clear liquid coupling agents are what are being provided. The mechanical strength and adhesion of these products are improved.
