TIS-390 Spray Silicone Adjuvant: Super-Spreading Silicone Surfactant for Enhanced Agrochemical Performance
Introduction
TIS-390 is a high-performance spray adjuvant based on a trisiloxane ethoxylate structure, designed to significantly enhance the effectiveness of agricultural chemical applications -1. As a super-spreading surfactant, it delivers performance far beyond conventional adjuvants, making it an essential tool for modern farming operations seeking to optimize crop protection and nutrition programs.
Key Product Features
Super-Spreading Performance
TIS-390 spray silicone adjuvant stands out for its remarkable ability to reduce surface tension. At a concentration of just 0.1 wt%, it achieves an aqueous surface tension of less than 22 mN/m -1. To put this in perspective, a conventional nonionic surfactant (octylphenol ethoxylate with 10 EO units) at ten times the concentration (1.0 wt%) achieves only 30 mN/m -1. This dramatic reduction in surface tension enables superior spreading and coverage of spray solutions on leaf surfaces.
Enhanced Agrochemical Uptake
The super-spreading properties of TIS-390 allow spray droplets to spread rapidly across leaf surfaces, reducing contact angles and significantly increasing spray coverage -1. Under favorable conditions, it promotes rapid absorption of agrochemicals into plant tissues through stomatal infiltration. Once absorbed in this manner, the active ingredients become rainfast, improving application reliability and reducing the need for reapplication -1.
Broad Compatibility
TIS-390 is nonionic in nature, making it compatible with a wide range of agrochemical formulations, including herbicides, fungicides, insecticides, and plant growth regulators -1. Unlike some trisiloxane alkoxylates that can be negatively affected by oil-based formulation components (such as EC formulations or spray oils), TIS-390 demonstrates enhanced spreading performance even in these challenging formulations -1.
