Silicone Surfactant PASS as Super Spreader, Bio-compatible

Bio-compatible organosilicone super spreader PASS is a nonionic trisiloxane surfactant that delivers superior spreading while meeting environmental and formulation compatibility requirements in crop spraying

CAS No.: 67674-67-3

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

Bio-compatible organosilicone super spreader PASS showing enhanced leaf wetting and complete spray spreading compared with water alone in foliar application

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

Specifications

Appearance	Colorless to light amber liquid
Surface tension	20.0-22.0 mN/m (0.1%)

Product Usage

As a tank mix adjuvant

Dosage: 0.025%-0.1% of the spraying solution, based on the agrochemicals used with, generally 5 ml PASS per 15 liters spray solution is suggested.

It is best to use the preparation within 24 hours and within a pH range 5-8.
