ABSTRACT:
The disclosure concerns an improved method and apparatus for employing filled resins in chopper type fiberglass systems. The new technique is characterized by a special mixer for the resin and filler which produces a product which does not settle as fast as prior filled resins, and which has a viscosity low enough to permit use of the conventional chopper equipment employed with unfilled resins. The resin-filler mixture may be pumped directly from the mixing apparatus to the chopper gun and is free of any tendency to set in, and thus clog, the mixer.
