Product Description
EMULSOL K-SIL HS-312 spreader is a new, hydrolytically stable silicone with a broad pH stability range allowing formulators many options to incorporate it as a cost-effectiveadjuvant in many in-can pesticide products.
EMULSOL K-SIL HS-31.2 spreader is an excellent candidate to consider for superb spreading performance and extended stability in water-based formulations between pH 3 to pH 12. This product offers excellent performance as a spreader, relative to commercial surfactants, for the effective delivery of many in-can pesticides with lower spray application rates. In addition, EMULSOL K-SIL HS-312 spreader is used at much lower rates compared to conventional surfactant adjuvants.
EMULSOL K-SIL HS-312 spreader is compatible with many agrochemical components and can therefore be dispersed into water-based agricultural formulations yielding products with excellent storage stability.
Key Features and Typical Benefits
- 4-10X more surface spreading than surfactant adjuvants
- Improves spray coverage on crops
- Promotes spray volume reduction
- Compatible with Ag formulations
- Excellent stability with Ag formulations between pH 3-12

How to Use
EMULSOL K-SIL HS-312 spreader is a cost-effective spreader that can be used in in-can pesticide products in the 3-12 pH ranqe, It can be added as a component directly to such formulations to provide better spreading during spray application. The addition levels of EMULSOL K-SIL HS-312 spreader are dependent on the level of spreading required in the spray application of the pesticide. A recommended use rate is 5% of the total pesticide formulation, or 0.05% - 0.20% of the tank-mix mixture.
Performance Data
Because the EMULSOL K-SIL HS-312 spreader has very low surface tension, the contact angle of spray solutions on leaf surfaces is reduced compared to other surfactant adjuvants. This important property is shown in Figur.e 1 below, which illustrates EMULSOL K-SIL HS-312 spreader having less than 50 contact angle relative to the Octylphenol Ethoxylate containing 10 EO units (OPE-10), having a 310 contact angle. It is also important to note that the lower EMULSOL K-SIL HS-312 spreader contact angle is achieved at much lower concentrations compared to the OPE-lO surfactant concentration.
