CONSTITUTION:An inorg. fiber, an inorg. powdery filler, stearic acid, metallic soap, a hardener and a colorant are added to a solid amino resin. The mixture is mixed, kneaded, crushed and optionally granulated. As the solid amino resin, an amino resin alone such as a urea resin, a melamine resin, a guanamine resin, etc., their mixture or their modified resin is used. |
