Athon SW 1081 Fluid is low molar weight ethoxylated trisiloxane, submitted to further separation and purification procedures.
Athon SW 1081 Fluid is a water-soluble silicone surfactant with excellent spreading and surface tension reduction properties.
Athon SW 1081 Fluid lowers the surface tension of water to 20-22 mN/m at proportions which may reach 0.01% by weight. This very low surface tension leads to high spreading or wettability of aqueous solutions on virtually all known surfaces.
Trisiloxane-based materials exhibit the super-spreading property – the ability to cover a much larger area than ordinary surfactant solutions. Even fluoroalkyl surfactants, which reduce surface tension to even lower levels, do not have the ability to over-spread. Actives present in solutions containing Athon SW 1081 are carried and penetrate through small openings normally protected from water by high surface energy – for example, plant leaf stomata, textile fiber channels or biofilms. These thin aqueous films are subject to rapid evaporation, often allowing rapid drying in textiles and rigid surfaces.
