Request SDS →Polyether-modified trisiloxane (CAS 27306-78-1) is a silicone-based nonionic surfactant. Its very low surface tension produces rapid wetting and spreading, and it is used as a superspreading spray adjuvant in agrochemical formulations and as a wetting and flow agent in coatings and other formulated products.
Frequently Asked Questions
What is polyether-modified trisiloxane?
It is a silicone-based nonionic surfactant (CAS 27306-78-1) consisting of a trisiloxane backbone modified with polyether groups. Its very low surface tension produces rapid wetting and spreading, which is why it is widely used as a superspreader.
What is polyether-modified trisiloxane used for?
It is used as a superspreading spray adjuvant in agrochemical formulations to improve wetting and penetration, and as a wetting and flow/leveling agent in coatings and other formulated products. It functions as a general nonionic surfactant and spreading aid.
What is the use of trisiloxane surfactant in agriculture?
As a spray adjuvant, the trisiloxane surfactant dramatically lowers spray-solution surface tension to give superspreading coverage and faster wetting of leaf surfaces. This improves deposition and uptake of the active ingredients in the tank mix.
What products contain polysiloxane surfactants like this?
Polyether-modified trisiloxanes appear in agricultural adjuvants and tank-mix wetting aids, and in coatings as flow and leveling additives. They are also used as general spreading surfactants in various formulated industrial products.
How is this silicone surfactant supplied in bulk and what is the cost?
It is supplied as a liquid in bulk packaging such as drums, totes, and IBCs. Pricing is volume- and grade-dependent; request a bulk quote with your target quantity for current pricing, lead time, and SDS/CoA.
