Silwet* L-77 Super Spreader

High performance super-spreader with exceptional spreading and stomatal infiltration when needed

Silwet L-77 spreader 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 spreader are able to wet PTFE or help wet and penetrate hydrophobic surfaces such as mineral ores or the leaf of a plant.

More About Silwet* L-77 Super Spreader

Because of its low CMC values, Silwet L-77 spreader can achieve optimum performance at levels as low as 0.1%. It can be effective in a variety of water-based formulations helping the end-use application achieve outstanding levels of performance due to better substrate wetting. 

Silwet L-77 spreader is frequently used in a variety of applications, because of its ability to reduce surface tension and rapidly spread on difficult to wet surfaces. Silwet L-77 spreader can work synergistically with many conventional surfactants, thereby providing a greater degree of spreading than the individual surfactants alone.  However, there are some conventional surfactants that antagonize the spreading of Silwet L-77 spreader. Please ask your Momentive representative for more information.
