Low surface tension and low surface energy of silicone

The main chain of organosilicon is very flexible, and its intermolecular force is much weaker than that of hydrocarbons. Therefore, it has lower viscosity than hydrocarbons of the same molecular weight, weak surface tension, low surface energy, and strong film-forming ability. This low surface tension and low surface energy are the main reasons for its many applications: hydrophobicity, defoaming, foam stability, anti-sticking, lubrication, glazing and other excellent properties.
