摘要
Synthetic resin compns. for moulding, coating, for use as mastics and as potting compns. e.g. for electrical equipment, comprise: 20-80 (vol.)% of a thermosetting resin and a hardener, 80-20% inorg. filler and 1-30% of a microfiller (I) of particle size 5 mu and at least partly of spheroidal shape, the % being based on total vol. The compsn. is prepd. by (a) dispersing the (I) in the resin before adding the other components (b) dispersing (I) in the hardener before prepn. of the total mixt., (c) dispersing (I) in the resin and the hardener or (d) mixing (I) with a mixt. of the resin, the hardener and the filler. The use of (I) enables a low resin content to be used even if the compsn. is to be self-levelling, the compsn. being further easy to work and apply by trowel.
