Abstract
A whitewater dispersant system containing a cationic surfactant and a cationic polyacrylamide. The viscosity modifier of the present invention may include amounts varying from 0 to 90% of a nonionic cellulosic viscosity modifier. The resulting whitewater is particularly effective in dispersing glass fibers in a slurry which is used to form a glass mat. The whitewater preferably has a viscosity lying in the range of from 2 to 12 cps and most preferably about 8 cps.
