Cas No. 1873-88-7
More details are coming….
LS-418
- HPTSO , Cas No. 1873-88-7 over 99.5% purity
- 1,1,1,3,5,5,7-Heptamethyltrisiloxane, a key raw material for polyether-modified trisiloxane surfactants.
- Polyether-modified trisiloxanes have wide applications in agrochemical adjuvants and coatings.
- Used for aromatic C-H silylation and synthesizing specialized trisiloxane derivatives.
- Agricultural adjuvant, sensory enhancer, and polymer solubilizing agent applications.
LS-806
- HPTSO modified , Cas No. 27306-78-1
- Equivalents for MOMENTIVE Silwet 806
- a low-foaming, super-spreading surfactant with a low freezing point.
- lower spray solution surface tension more than conventional adjuvants, enabling rapid wetting, exceptional spreading, and better deposition.
- The enhanced spreading and wetting properties can improve the efficacy of pesticides.
LS-408
- HPTSO modified , Cas No. 27306-78-1
- Equivalents for DOW Q2-5211 |MOMENTIVE Silwet 408 | Degussa S 240 or BREAK-THRU® S 240
- a super-spreading, trisiloxane-based surfactant that enhances agricultural chemicals, including water-soluble herbicides on grasses.
- lowers surface tension more than typical adjuvants, enabling rapid uptake and stomatal infiltration for improved rainfastness and reliability.
- is compatible with oil-based components and provides better spreading compared to other organosilicone adjuvants, making it suitable for diverse agrochemical uses.
LS-408M
- HPTSO modified， Cas No. 27306-78-1
- Equivalents for MOMENTIVE Silwet L-77
- A specialized silicone surfactant that boosts agricultural spray performance by improving coverage and adhesion.
- Helps spray spread evenly and penetrate deeper, allowing active ingredients to work more effectively.
- Enhances rainfastness, so treatments remain protective after weather events.
- Can be used with various foliar and soil-applied crop products, including organics, at low optimized rates.
