Precision Silicone Adjuvants for Every Spraying Need

At Shanghai Profirst Co., Ltd., we’ve refined our silicone surfactant technology into different targeted solutions.

Our core lineup:

PASS – Our bestselling silicone super spreader. It delivers ultimate wetting and coverage by reducing surface tension to ~21 mN/m (0.1% aq.), setting the standard for performance.
PASS-LF – All the power of PASS, upgraded. Engineered with low foaming and a low pour point, it ensures easier tank-mix handling and reliable performance in cooler conditions.
Pro-MSO Plus – The synergistic blend. It combines the spreading power of silicone with the deep penetration of MSO. This is the ideal choice for systemic herbicides and tackling tough, waxy weeds.
Synergy 100 – The balanced performer. It merges silicone’s superior spreading with the stable, reliable properties of other non-ionic surfactants, offering versatile performance across various tank-mix applications.
