Note: The pH is 7-8 and the viscosity @ 20 rpm LVT is 20,000 cps.
When a self-thickening latex such as "Hycar" acrylic 2671X13 is used, the level of "Carbopol" resin needed will be lower.
Agitate the latex moderately at low speed. Avoid cavitating to prevent air bubbles. Add the 10% "Carbopol" 940 solution rapidly. Agitate until homogeneous (15-20 min). Neutralize with ammonium hydroxide to desired pH. Add the thermosetting resin, then the antifoam agent. Agitate until homogeneous. |
