zirconium oxide/10.00
"carboopol" 941/0.10
sodium hydroxide (10% sol'n)/0.58
water/89.32 |
| 配制方法： |
brookfield visc, 20 rpm-2975 cP or mPa.s pH-10.0 carefully disperse the "carbopol" 941 resin in half the water. add the sodium hydroxide while stirring. in a separate container, disperse the zirconium oxide in the remainder of the water, then ad this to the mucilage of "carbopol" 941 slowly, in a steady stream, with agitation.
note: it is very important to add the ingredients in the proper order.
if the pigment is added before the sodium hydroxide, it will immediately flocculate. the pH of the neutralized mucilage of "carbopol" 041 resin must be at least 9.5 to prevent flocculation. |
