Spontaneous Resin Emulsion |
| 配方組成: |
Where no colloid mill is available and an emulsion of wide particle-size range is satisfactory, spontaneous resin emulsions may be prepared by using formulae such as No.1 and 2 that follow. A procedure for preparing this type of resin emulsion is: Step 1. Dissolve the resin in the solvent at room temperature and then add the oleic acid. Best results are obtained when this resin solution has a viscosity of 25 to 35 poises at room temperature. The cited proportions of resin |
