Polyorganosiloxane composition

摘要

The present invention relates to a polyorganosiloxane composition and, more particularly, to a polyorganosiloxane composition having good curing properties at room temperature and producing cured materials having good water absorption properties. The polyorganosiloxane composition comprises: (A) a curable silicone rubber composition containing polysiloxane which is liquid at room temperature as a base polymer; and (B) a polymer containing acrylic acid or an alkali metal salt of acrylic acid as a monomer unit.
