Silicone Surfactant PASS-77 as Super Spreader

Organosilicone Spreaders

PASS-77 is a nonionic organosilicone 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.
27306-78-1

PASS-77 is a 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-77 performs much better than conventional spray adjuvants in lowering aqueous surface tension and reducing contact angle of spray solutions on leaf surfaces.

PASS-77 into the market in Year 2012, because it is the first one of silicone surfactant series, some customers prefer it, it still has some markets.

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
