The working principle of silicone additives

Jan 29, 2018

In the material to add, play a supporting role of organic silicon compounds, known as the silicone additives. Its working principle depends on the type of additives, the role of. Such as silane coupling agent, added to the adhesive to increase the bonding strength of the role. The principle is that the silicon alkoxide in the coupling agent molecule can undergo a dealcoholization reaction with hydroxyl groups on the surface of the substrate to be bonded to form a chemical bond and the other end of the coupling agent molecule must be an active group capable of reacting with the adhesive or At least it is a group that binds to the adhesive molecule so that it acts as a chemical bond to the surface of the adhesive molecule and the adherend. Other hydrophobic effect, reduce the role of surface energy.
