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.

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%.
