PURPOSE: A thermosetting castable composition of excellent preservability, prepared by adding talc as a filler to a composition containing a PBd-styrene- TMPTA resin, t-butyl peroxybenzoate, and manganese naphthenate. n CONSTITUTION: A thermosetting castable composition is obtained by adding 70W 140PHR talc as a filler to a composition containing a polybutadiene prepolymer (polybutadiene maleinized on both ends, PBd)-styrene monomer trimethylolpropane triacrylate (TMPTA) ternary resin system, t-butyl peroxybenzoate, and manganese naphthenate. The above composition can be given a longer pot life by replacing at least part of the talc with calcium carbonate by adding 90PHR or below calcium carbonate. n COPYRIGHT: (C)1984,JPO&Japio |
