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．
