Thickening Stoddard Solvent |
| 配方组成： |
Methanol/10
"Carbopol" 941/1
"Stoddard Solvent"/100
Dodecylamine/4 |
| 配制方法： |
Carefully disperse the "Carbopol" resin in the "stoddard Solvent," and then add the amine. Little or no thickening will occur. Add the methanol rapidly with g ood mixing to minimize local swelling and clumping. The "Carbopol" will swell and gel the system to give a Brookfield, 20 rpm, viscosity of 1000 cps. Higher viscosities would prevail if "Carbopol" 934 or 940 is used or if increased amounts of Carbopol resin-amine are employed. |
