Agricultural Silicone Spreading and Penetrating Agent
Chemical name: Polyalkyleneoxide Modified Trisiloxane
Cas No: 67674-67-3
Equivalent Product: Momentive Silwet 408, Break thru S 240-Evonik
The chemical composition of ZG-618 wetting agent is a special modified polysiloxane copolymer. It has high - efficiency surface activity, can significantly reduce the surface tension of water - based systems, improve wettability and leveling properties, and is suitable for multiple fields such as agricultural adjuvants, coatings, inks, leather processing, etc.
Appearance: Colorless to light amber transparent liquid.
Viscosity at 25℃: 20 - 60 cP.
Surface tension (0.1%): < 21.5mN/m.
Refractive index at 25℃: Between 1.440 and 1.455. The pH value is neutral, but the system compatibility needs to be tested before use.
Agricultural Field: As a pesticide adjuvant, it promotes the spreading and penetration of the liquid medicine on the leaf surface.
Water - based Coatings: It improves the wettability of difficult - to - adhere substrates, prevents defects, and enhances the leveling and gloss of the paint film.
Printing Inks: It enhances the adhesion of inks to various substrates, reduces ink - flying and missed printing.
Leather and Synthetic Leather: It optimizes the release effect of the release paper, improves the coating uniformity and hand - feeling.
Powder Dispersion Systems: It assists in the dispersion of powders in water - based media and prevents agglomeration.
The addition amount is 0.1% - 1.0% of the total amount of the system, and the specific amount should be adjusted according to the formula.
It can be added directly or pre - diluted with deionized water before adding. It is recommended to add it with low - speed stirring to avoid high - speed shearing from damaging the molecular structure. The system compatibility test should be carried out before the first use.
Packaging specifications include 25kg, 200kg, and 1000kg plastic drums.
It should be stored in a sealed manner in a cool and dry place, avoiding direct sunlight. The shelf - life at room temperature is 24 months. After opening, use it as soon as possible and store it in a sealed state.
