Silicone Adjuvant is a special surfactant, the main component of which is polyether modified trisiloxane.
What is silicone adjuvant?
The special structure of polyether modified trisiloxane, makes it have extremely low surface tension ( 0.1% (aq), <21mN/m), so as to obtain excellent spreading, wetting and penetrating ability.

The characteristics of silicone adjuvants
Durable to rainwater erosion
Fast conduction and absorption, durable to rainwater erosion.
Stomatal Permeability and Transitivity
Penetrates through stomata and facilitates the conduction of pesticides within the plants
Super spreadability
Spread pesticides quickly on leaves
Super wettability
Reduce surface tension to 21mN/m
Why do you need silicone agricultural adjuvants?
If pesticides are used alone:
1. Cannot be absorbed immediately.
2. It takes hours to penetrate into plant tissue.
3. Droplets are easy to rebound, gather, and drip, which affects absorption.
4. Easily washed away by rain.
