Methanol/5
"Carbopol" 941/1
Trichlorethylene/100
Di (2-ethylhexyl) amine/3 |
| 配制方法： |
disperse the Carbopol 941 in the trichlorethylene and then add the amine. Lastly, stir in the methanol. The methanol acts as a coupling agent to promote solubility of the Carbopol 941-amine salt.
The mix will thicken after the methanol addition and rise from an initial viscosity of 1675 cps to 2500 cps (Brookfield, 20 rpm) after 4 hours. It displays good age stability. |
