Silicone Agricultural Adjuvant TPD-309

Description

Composition: Polyalkyleneoxide Modified Trisiloxane

Chemical Name: heptamethyltrisiloxane, ethoxylated, propyl ether 

Cas No: 27306-78-1 

Silicone Agricultural Adjuvant TPD-309 is a non-ionic silicone surfactant with super spreading and penetrating properties, which can reduce the surface tension of spray liquid faster thantraditional adjuvants. At a concentration of 0.1% (wt.), the surface tension of water can be reduced to 21mN/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 
• High cloud point 
• Super spreading and penetrating agent

How to use

• Used as a component in agrochemical formulations

Because the silicone surfactant will be hydrolyzed under acidic and acidic and alkaline conditions, it is recommended that the pH be adjusted to 6.5~7.5 by a buffer to achieve the best performance.
The recommended dosage is 0.1~5%. 

• Used as a tank mix additive

Adjust the PH value of the formulations to 6-8. To achieve the best effect, the formulations should be used within 24 hours. The recommended dosage level is: 0.01-0.1%. 

• Used as an additive in coatings and paints 

TPD-309 is widely used in water based and solvent based coatings, ink, and paints. The recommended dosage level is: 0.1-1.0%.
