Abstract
Prodn. of a heat-cured, filled, modified MF resin compsn. (I) with good flow properties comprises plasticising a mixt. of 20-70 wt.% MF resin, 20-79 wt.% mineral and/or fibre filler (ground to 0.001-0.1 mm), 0.1-15 wt.% glycols and urea and/or triazine derivs., and opt. dicyandiamide, by roll-milling for 1-30 mins. at 60-140 deg.C. - Fillers are quartz powder, glass fibre and/or cellulose, amt. of MF resin is 30-60 wt.%, pref. glycol is ethylene glycol, and the mixt. is roll-milled at 80-110 deg.C.
