SILIA-2009 Agricultural Silicone Spreading and Wetting Agent
is a modified polyether trisiloxane and a kind of silicone surfactant with super ability of spreading and penetrating. It makes the water surface tension lower down to the 20.5mN/m at the concentration of 0.1%(wt.).
Characteristics
 Super spreading and penetrating agent
 Low surface tention
 High cloud point
 Nonionic.
Properties
Appearance: Colourless to light amber liquid
Viscosity（ 25℃， mm2/s）: 25-50
Surface tension（ 25℃， 0.1%， mN/m）: <21
Density（ 25℃）: 1.01～1.03g/cm3
Cloud point（ 1% wt， ℃）: >35℃

Application areas :
1. Used as spray adjuvant: SILIA-2009 can increase the coverage of the spraying agent, promote the uptake and decrease the dosage of the spraying agent. The SILIA-2009 is the most effective when spray mixtures are
(i) within a PH range of 6-8,
(ii) prepare the
spray mixture for immediately use or within 24h preparation.

2. Used in agrichemical formulations: SILIA-2009 can be added in the original pesticide.
The dosage is depended upon the type of formulations.
The recommended dosage is 0.1～0.2％ wt% of the total water based systems and 0.5% of the total solvent based systems.
A thorough application test is necessary to get an ideal result.
It has different charateristics when used in different systems.
