Cloud Point<10°C

Polyalkyleneoxide Modified Heptamethyltrisiloxane(SEGA-66) is a modified Trisiloxane, and is an organic silicone surfactant with super ability of spreading. It makes the water surface tension lower down to the 20.5mN/m at the concentration of 0.1%(wt.).


1. SEGA-66 : Surfactant for agricultural use

 Reduce the surface tension of the droplets and make the droplets fully extended so that the use rate of pesticide can be enhanced.


2. SEGA-77 : Leather processing additive

As a additive to meet the special demands of substrate, such as , substrate wetting, distributed evenly, defrothing, releasing , helping strip ,good handfeeling etc.


3. SEGA-88 : Textile additive

Textile functional finishing,such as antibiotic finish, water-proof finish, radiation resistant finish, resistance to melt finishing of high-speed sewing machine line etc.


4. SEGA-99 :Coating additive

Improve the coating wettability and enhance binding force of coating and substrate.Increase paint surface brightness and smooth property, strengthen isolation avoiding adhesion. Perfect coatings for leveling and storage stability.

Packing:200 L /drum or according to special requirement
