Silicone Spreading and Penetrating Agent HY-109
Similar to Silwet L-77
Agricultural Silicone Spreading and Penetrating Agent HY-109 is a modified trisiloxane, and it has excellent ability of penetrating and spreading. It is one kind of organic silicone surfactant which can lower down the water surface tension to to the 20.5mN/m with concentration of 0.1% (wt.).

Features
It is prime penetrating and spreading agent with low surface tension. It is non-ionic with high cloud point.
Applications
Used as spray adjuvant: it can enlarge the coverage area of the spraying agent, increase the uptake and reduce the dosage of the spraying agent. It is the very effective when the PH range of spray mixtures is 6-8 and it is used immediately after the spray mixture is prepared or not over 24h after preparation
When it is used in coatings and paints, it can be widely applied in solvent based and water based coatings and paints. It is effective with low dosage. it is excellent penetrating and wetting agent especially used in water based coatings and paints. It provides high surface activities and low surface tension. It can improves the levelling, flow, smoothness and wetting of the substrate, etc.
Use Method
The dosage is depended on different formulations. The recommended dosage is 0.5% of the total solvent based systems and 0.1～0.2wt % of the total water based systems. A detailed application test is needed to get satisfying results. It shows different properties when used in different systems.
Packing methjods
20L, 200L plastic drums, or up to clients request.
