PEL-SIL 648 reduces the surface tension of aqueous solutions significantly lower than conventional nonionic surfactants can. Even at concentrations as low as 0.01 percent, PEL-SIL 648 will reduce surface tension below 23 dynes/cm. It produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves. PEL-SIL 648 allows complete coverage with herbicides, insecticides, fungicides and other agricultural chemicals. It is a low molecular weight nonionic silicone polyether surfactant, developed to improve the wetting, spreading and penetration of agricultural chemicals. It may be used as an ingredient in pesticide products, or as a tank-mix adjuvant for foliar applied chemicals. PEL-SIL 648 meets the requirements of US EPA regulation 40 CFR 180.910 regarding “tolerances and exemption from tolerances for pesticide chemicals in or on raw agricultural commodities.” It is approved for both food and nonfood use.
