Silwet L-77 silicone surfactant is a modified trisiloxane that combines a very low molecular weight trisiloxane with a polyether group. It is characterized by remarkable interfacial activity, which can result in dramatically reduced aqueous surface tension, outstanding spreading or leveling and stabilized foam. All of which may be achieved using a fraction of the typical concentration levels of organic or fluorocarbon surfactants. These effects are so powerful, that the water solutions using Silwet L-77 silicone surfactant are able to wet PTFE or help wet and penetrate hydrophobic surfaces such as mineral ores or the leaf of a plant.
