Silicone Surfactant PASS-LF as Low Foaming Super Spreader

Organosilicone Spreaders

PASS-LF is a nonionic low foaming super spreading adjuvant for foliar-applied agrochemicals, including herbicides, insecticides, fungicides, fertilizers, and plant growth regulators, designed to improve spray coverage, reduce surface tension, and enhance uptake efficiency in agriculture

CAS No.
134180-76-0

PASS-LF is a low foaming super spreading agent for foliar-applied agrochemicals, including herbicides, insecticides, fungicides, plant growth regulators, fertilizers and micronutrients.

As a nonionic surfactant based on polyether modified trisiloxane, PASS-LF performs much better than conventional spray adjuvants in lowering aqueous surface tension and reducing contact angle of spray solutions on leaf surfaces.

PASS-LF into the market in Year 2015 after two years reseach, because it is less foam than PASS, more and more customers accept PASS-LF, the sales is increasing these years.

Outstanding Merits

  • Low surface tension leads to enlarging droplet coverage
  • To improve the uptake of spraying solutions by stomatal absorption thus enhance the efficacy and rainfastness
  • To save the use of water and agrochemicals
  • Low foam property makes it easier to handle than general silicone surfactant
