Silicone resin compositions

The resin composition comprises (a) 100 parts by weight of a silicone resin, (b) from 5 to 300 parts by weight of a phenolic prepolymer constructed by repeated xylylene units and phenylene units having phenolic hydroxy groups, (c) a silanol-condensation catalyst, and (d) a curing catalyst for phenol...

Beschreibung
Zusammenfassung:	The resin composition comprises (a) 100 parts by weight of a silicone resin, (b) from 5 to 300 parts by weight of a phenolic prepolymer constructed by repeated xylylene units and phenylene units having phenolic hydroxy groups, (c) a silanol-condensation catalyst, and (d) a curing catalyst for phenol resins. These compositions have a very good processability for fabrication by molding, laminating or by other means, and the fabricated articles can enjoy the excellent properties inherent in silicone resins with respect to thermal stability and electric properties, and in phenolic resins with respect to mechanical strengths and anti-solvent resistance.
