Silicone Agricultural Adjuvant TPD-312R is a non-ionic silicon surfactant with super expansion ability, which has excellent properties of acid and alkali resistance (pH 3-10), it can be added to formulations. At a concentration of 0.1%(wt.), the surface tension of water can be reduced to 22mN/m, which can effectively reduce the contact angle between the spray liquid and the leaf surface, thereby increasing the spray coverage, it can promote the absorption and rain fastness of pesticide spray, thereby increasing effectiveness.
Features
- Non-ionic
- Good resistance to low temperature
- Good resistance to acid and alkali
- Enhancing the absorption of pesticides
