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）Acetone ：Isopropanol = 65:35
3）Toluene ：Isopropanol = 4:1
4）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．
