Super Spreading Surfactant SiRS-2686

Description

SiRS-2686 is a super spreading surfactant based on trisiloxane ethoxylate. The SiRS-2686 spray adjuvant lowers the aqueous surface tension of spay solutions. Typically, SiRS-2686 spay adjuvant ( @ 0.1% wt%) gives the aqueous surface tension lower than 22 mN/m, which is much better than conventional adjuvant.It efficiently decreases contact angle between spray liquid and leafs, increases the covering area and promote the agrochemicals absorption.

Features

• Low foaming
• Low pour point for low temperature application

Product Data

Application

Used as spray adjuvant

SiRS-2686 can increase the coverage of the spraying agent, promote the uptake and decrease the dosage of the spraying agent.Typical proportion as following:

• Plant growth regulators: 0.025-0.05%
• Herbicide: 0.025-0.15%
• Pesticides: 0.025-0.1%
• Antiseptic：0.015-0.05%
• Fertilizers and trace elements: 0.015-0.1%

Firstly dissolve the pesticide, add SiRS-2686 after the uniform mixture of 80% water, then add water to 100% and mix well The water amount is suggested to be reduced to 1/2 or 2/3 of the normal amount , average pesticide usage reduced to 70-80% of the normal amount. A small aperture nozzle is helpful with the spray speed.

Used in agrochemical formulations:

SiRS-2686 can be added in the original pesticide. When added to the original pesticide, suggested rate 0.5%-8% of the original pesticide. Adjust the pH of pesticide prescription to 6-8. The amount is flexible to adjust for different kinds of pesticide and prescription. Prior compatibility test and stepwise test is necessary to determine optimum dosage.
