Polyether Modified Polysiloxane LA-43
LA-43 is a high molecular weight polyether modified polysiloxane. It is a highly compatible silicone non-ionic surfactant, which can significantly reduce the surface tension of the liquid, and has interface wetting and leveling properties. LA-43 provides a wetting, smooth hand feel. It can be also used in coatings of water-based and solvent systems.
