Liwet 408 spray adjuvant (CAS: 67674-67-3)is a polyether trisiloxane. In aqueous solutions,
it gives super spreading and does dramatically reduce surface tension.
Typically, Liwet 408 spray adjuvant reduces the surface tension of aqueous 
agricultural mixtures significantly. 
At concentrations as low as 0.1 percent, Liwet 408 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.
Liwet 408 spray adjuvant is nonionic in nature, making it useful with a broad 

range of agrochemical formulations.

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

Typical Applications
●  Crop protection products
●  Herbicides
● Insecticides
●  Fungicides
● Nutrients and plant  
● growth regulators
