Polyether Modified Trisiloxane
Polyether Modified Trisiloxane is a high-performance organosilicone nonionic surfactant featuring exceptional super-spreading capabilities. It drastically reduces the surface tension of aqueous solutions down to 20-22 mN/m, far outperforming conventional surfactants. In agrochemicals, it functions as a premium silicone spray adjuvant that dramatically improves pesticide wetting, stomatal penetration, and rainfastness on foliage. In industrial applications, it is widely utilized as a wetting, leveling, and anti-crater additive for waterborne coatings, inks, and cleaning formulations.

Polyether Modified Trisiloxane is an advanced, non-ionic organosilicone surfactant engineered to deliver exceptional surface activity. By significantly lowering the surface tension of aqueous solutions to an ultra-low level of 20.0 - 22.0 mN/m, it enables rapid spreading, wetting, and penetration on difficult-to-wet surfaces.
In agricultural applications, it acts as a premier tank-mix and formulation adjuvant, dramatically enhancing the efficacy of insecticides, fungicides, herbicides, and foliar fertilizers by ensuring maximum leaf coverage and stomatal infiltration. In industrial sectors, it functions as an essential wetting, leveling, and anti-crater additive for waterborne coatings, inks, and cleaning formulations.
Key Performance Benefits
Ultra-Low Surface Tension: Reduces aqueous spray or coating surface tension far below conventional non-ionic surfactants, ensuring instantaneous droplet flattening.
Superior Foliar Penetration: Promotes rapid stomatal entry of agrochemicals into plant leaves, significantly boosting resistance to wash-off and improving rainfastness.
Enhanced Spreading & Coverage: Eliminates dry spots and ensures uniform distribution of active ingredients across waxy or hard-to-wet leaf surfaces.
Improved Coating Quality: Acts as an effective leveling and anti-crater agent in waterborne industrial paints and inks, preventing surface defects.
High Chemical Stability: Exhibits excellent compatibility with a wide range of pesticide formulations and water-based industrial systems.
Recommended Applications
Agrochemicals & Crop Protection: Used as a tank-mix additive or formulation ingredient for insecticides, fungicides, herbicides, plant growth regulators, and liquid fertilizers.
Industrial Coatings & Inks: Utilized as a wet-out and flow modifier in waterborne paints, varnishes, and printing inks to eliminate surface tension gradients.
Cleaning & Surface Care: Integrated into industrial and household cleaning formulations for superior wetting on hard surfaces.
Packaging & Storage
Standard Packaging: 1000g / Bottle (High-Density Polyethylene - HDPE bottle designed for safe chemical storage).
Storage Conditions: Store in a cool, dry, well-ventilated area away from direct sunlight and extreme heat. Keep containers tightly sealed when not in use.
