Organosilicone Adjuvant H-8408

H-8408 is a modified trisilioxane, is an organic silicone surfactant with super alility of spreading. It is a non-ion surfactant has the structure of type "T". H-8408 have super ability of spreading.It makes the water surface tension lower down to the 20.5mN/m at the concerntration of 0.1%(wt). After the mixture with the pesticide solution at the certain proportion, It can lower the contact angle between the spray and foliage, which can enlarge the coverage of the spray. Furthermore, H-8408 can make the pesticide absorbed through the stomatal leaves, which is extremely effective for improving efficacy, reducing amount of pesticede, saving cost, reducing environmental pollution caused by pesticides.
