SILICONE ADJUVANT SILWAY 247
 
SILWAY247 Polyether Modified Silicone Oil Surface Active Agents Spray Adjuvant CAS.27306-78-1
 
Silway 247 spray adjuvant is a polyether trisiloxane. In aqueous solutions, it gives super spreading and does dramatically reduce surface tension. Typically, Silway 247 spray adjuvant reduces the surface tension of aqueous agricultural mixtures significantly. At concentrations as low as 0.1 percent, Silway 247 spray adjuvant reduces surface tension below 22 mN/m, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves. Silway 247 spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations.
 
 
Typical Applications
  • Crop protection products
  • Herbicides
  • Insecticides
  • Fungicides
  • Nutrients and plant growth regulators
 
Key Features
  • Superspreading for exceptional spray coverage of crop and plant surfaces
  • Up to 70% spray volume reduction to lower water use and application costs
  • Excellent penetration providing better pesticide uptake and efficacy
  • Better spray treatment adhesion on crop and plant surfaces Rainfastness to lower pesticide wash-off and waste
  • Lower use levels than non-silicone surfactants
  • nonionic

Usage
  • Used as a component in agrochemical formulations. Although organosilicone surfactants are subject to hydrolysis under acidic or basic conditions, optimum performance is achieved by buffering the formulation to pH 3.0-9.0. Additionally, it is recommended that Silway 247 spray adjuvant be used at a concentration of at least 5%, based on the total formulation.
  • When used as a tank-side adjuvant，it can improve spray coverage, improve uptake or allow for a reduction in spray volume.
  • Most effective as a tank-side adjuvant when spray mixtures are used within 12 hours of preparation. Silway 247 spray adjuvant has been used successfully in spray applications globally. Typical applications include:
