SILICONE SURFACTANTS
"Super Wetting/Spreading Agents" which lower surface tension beyond that possible by conventional nonionic surfactants. There are two types of silicone surfactants: 1. Water-soluble which spreads the water droplet prior to drying, and 2. 0il soluble, which spreads the oil fraction of a spray droplet after the water, has evaporated. Some silicone surfactants are blended with co-surfactants to minimize excess evaporation and run-off: Primary use is with herbicides, insecticides, PGR's and fungicides where extra-wetting and superspreading is needed. |
