Lo-277

Countertype Product: Silwet L-77
CAS NO.: 27306-78-1
Lo-277 is a superspreading surfactant based on a trisiloxane ethoxylate, it helps lower the aqueous surface tension more
effectlively than conventional spray adjuvants.
Lo-277 promotes rapid uptake of agrochemicals into stomata infiltration.
Features

• Nonionic, making it useful with a broad range of agrochemical formulations
• Superspreader for soluble liquid and emulsifiable concentrate formulations
• Improves spray coverage significantly
• Promotes rapid uptake of agrochemicals (rainfastness)
• Superspreading and penetrating of spray agricultural chemicals
• Improves appication reiabiity
• Reduces the residues of pesticides

Typical properties

• Active Content percent: 100%
• Appearance: Colorless to pale yellow clear liquid
• Cloud Point (0.1 wt%) : ＜10 ℃
• Freezing point: <2 ℃
• Viscosity at 25°C (77°F): 15-25 cSt
• Surface tension (0.1% aq.): 20-22mN/m

Use rates
Lo-248 may be use as a component in agrochemical formulations. Although organosilicone surfactants are subject to
hydroysis under acidic or basic conditions, Lo-248 may be still stable while the pH value of agrochemical formulation falls
in 5-8
AS a tank mix adjuvant
Lo-248 is most effective as tank-side adjuvant to improve spray coverage, to improve uptake or to allow for a reduction in
spray volume, as Lo-248 provides adequate coverage in many low volume spray applications at rates between 0.025% and
0.1%.
Typical applications as follows

Application	Rates
Herbicides	0.025%-0.15%
Insecticides	0.025%-0.1%
Fungicides	0.015%-0.05%
plant growth regulators	0.025%-0.05%
Fertilizers and micronutrients	0.015%-0.1%

Storage
Store in dry and ventilation place under 40℃, remain original package cosed.
Package
In 25KG, 200KG, 1000KG drum
