LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

Name: LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Agricultural silicone spreading and penetrating agent Silfluo LA-11 is a 100% active, nonionic organosilicone adjuvant formulated to drastically reduce the surface tension of agricultural spray liquors. Functioning as a premium super-spreader, it drives aqueous solutions down to <21.0 mN/m (at 0.1 wt%), ensuring comprehensive coverage on highly hydrophobic or waxy foliage. Notably, LA-11 features a unique low-foaming profile compared to conventional trisiloxane ethoxylates, minimizing equipment disruption during intense tank agitation.

Performance equivalent to Momentive Silwet L-77

Mechanism of Action of LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

Unlike standard carbon-based surfactants, the highly flexible siloxane backbone of Silfluo LA-11 triggers an immediate collapse of spray droplet surface tension. This results in extreme spreading behavior and facilitates the physical transport of active ingredients directly into plant stomata. This "stomatal flooding" guarantees rapid internal absorption, providing exceptional rainfastness and systemic delivery even under challenging weather conditions.

Tank-mix Application Guidelines of LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

Silfluo LA-11 operates efficiently at extremely low dosage rates, typically between 0.025% and 0.1% (e.g., 5g per 20kg of spray solution).

Recommended Use Rates of LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

Plant Growth Regulators: 0.025% - 0.05%
Herbicides: 0.025% - 0.15%
Insecticides: 0.025% - 0.1%
Fungicides: 0.015% - 0.05%
Fertilizers and Trace Elements: 0.015% - 0.1%

Preparation Protocol of LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

Fill the mixing tank to 80% capacity with water.
Introduce and thoroughly dissolve the required agrochemicals.
Incorporate the precise dosage of Silfluo LA-11.
Top off with the remaining water and agitate gently to minimize any potential foam generation.

Operational Optimization of LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

Spray Volume Reduction: Integrating Silfluo LA-11 empowers operators to safely cut total spray water volumes by 30% to 50%, while reducing active pesticide usage by 20% to 30% due to enhanced bioavailability.
Equipment Setup: Employ fine-droplet, small-aperture nozzles to maximize the stomatal penetration effect.
pH Stability Window: Optimal stability is achieved when the tank mix pH is maintained strictly between 6.0 and 8.0. Spray solutions must be utilized within 24 hours of preparation to prevent siloxane bond degradation.

IN-CAN FORMULATION CRITERIA of LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

When utilized as an inbuilt formulation additive, Silfluo LA-11 requires rigorous pH buffering (strictly between pH 6.5 and 7.5) to prevent hydrolysis. Formulators are advised to use concentrations ranging from 0.5% to 8.0% by weight depending on the matrix. Accelerated thermal aging and compatibility tests are mandatory to verify long-term phase stability prior to commercial release.

Package &Storage of LA-11 Agricultural Silicone Penetrant High Performance Polyehter Modified Trisiloxane

In 20Kg, 200Kg Plastic barrel or 1000kg, or up to clients request.
Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, shelf life is 24 months from the date of production. It is shipped as non-hazardous substance.
Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
