Agricultural Low foam Silicone Adjuvant QS-326

QS-326 is a low foam super spreading agent for foliar-applied agrochemicals, like herbicides, insecticides, fungicides and so on. Which is Polyether-modified polysiloxane surfactant. QS-326 spray adjuvant helps lower the aqueous surface tension more effectively than conventional spray adjuvants. Because QS-326 spray adjuvant is a super-spreading surfactant, the contact angle of spray solutions on leaf surfaces is reduced, leading to an increase in spray coverage.

Product description

Product Description:

Low foam silicone adjuvant is a super-spreading surfactant based on a polyalkyleneoxide modified heptamethyltrisiloxane. It is an spray adjuvant which can lower the surface tension of spray systems solutions, and leading to an increase in spray coverage. It can also reduce the mixture's foam.
