Product Detail

Description

Polyether modified polysiloxane spray adjuvant WET-628 is a high permeability surfactant/wetting agent based on a polysiloxane. It lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.


Type

Polyether modified polysiloxane

Key features

Nonionic

Medium spreading

High permeability

Promotes spray volume reduction

Promotes rapid uptake of agrochemicals (rainfastness)

Superspreader for soluble liquid and emulsifiable concentrate formulations

How to use

IN AGROCHEMICAL FORMULATIONS

-WET-628 may be 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 6.5-7.5. Additionally, it is recommended that WET-628 spray adjuvant be used at a concentration of at least 5%,based on the total formulation.


A TANK MIX ADJUVANT

-WET-628 spray adjuvant, when used as a tank-side adjuvant may be used to improve spray coverage, improve uptake or to allow for a reduction in spray volume. WET-628 spray adjuvant is most effective as a tank-side adjuvant when spray mixtures are 1) within a pH range of 5-8, and 2) used within 24 hours of preparation.

-High spray volumes, coupled with high surfactant rates, are not required to achieve sufficient coverage with WET-628 spray adjuvant. In fact, it has the potential to provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%.
