Organic solvent method of solubility and dissolution:
EC can be dissolved in various organic solvents, such as fatty acid (ethanol, isopropyl alcohol), other alcohols, ketones, aromatic and so on. Common solvent (volume ratio):
1)Toluene :Ethanol = 4:1
2)Ethanol
3)Acetone :Isopropanol = 65:35
4)Toluene :Isopropanol = 4:1
5)Methyl Acetate :Methanol = 85:15
Alcohols and aromatics in the viscosity of the mixture, with alcohol content higher and lower, when alcohol accounts for 30-35%, the lowest viscosity of the composition. Dissolution method: the EC under the stirring slowly add the container filled with a solvent until complete wetting dissolved.

Package:
20KG Bag or 12.5Kg Fibre Drum.

Storage and Shelf Life:

Thress years under cool, dry conditions in original packaging away from heat sources. It is recommended to use the product in rotation on a first-in first-out basis.
