APPLICATION
For maximum results, NOPCO DF-122 NS should be added early in the
coating preparation. High shear equipment ensures proper dispersion and
prevents spot and 'fish-eye' problems. Although specifically recommended
by Nopco, if a stock emulsion is used, 5 - 10% NOPCO DF-122 NS in
water is suggested with constant, mild agitation to maintain uniformity.
Normal application rates for NOPCO DF-122 NS are 0.1 to 0.3% of dry coating
pigment. |
