Silicone Surfactant PASS-77 as Super Spreader
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 leave 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
