Silwet* 408 Spray Adjuvant

Super-Spreader With Low Temperature Performance

A super-spreading surfactant based on a trisiloxane ethoxylate, Silwet 408 spray adjuvant can lower the surface tension of spray solutions beyond what is attainable with most regular adjuvants. This spray adjuvant can promote an aqueous surface tension of <22 mN/m (@ 0.1 wt %), far lower than 30 mN/m, which is typical from Octylphenol Ethoxylate surfactants containing 10 EO units (@ 1.0 wt %). As a super-spreading surfactant, Silwet 408 spray adjuvant offers rapid wetting, more coverage and better pesticide efficacy in many agrochemical spray applications.

More About Silwet* 408 Spray Adjuvant

Under specific conditions, Silwet 408 spray adjuvant helps accelerate the rapid uptake of agrochemicals into plants and foliage through stomatal infiltration, resulting in rainfast spray solutions and improved application reliability. Unlike many other trisiloxane alkoxylates, Silwet 408 spray adjuvant is not typically affected by oil-based components and can provide enhanced spreading in formulations containing such components, especially when compared to most other organosilicone-based adjuvants. Being nonionic in nature, Silwet 408 spray adjuvant may be considered for use across a broad range of agrochemical applications.    

Potential applications for Silwet 408 spray adjuvant include: 

  • Plant growth regulators
  • Herbicide
  • Insecticide
  • Fungicide
  • Fertilizers and micronutrients
