PURPOSE:To provide a water-resistant silicone rubber composition having excellent water-resistance and causing little variation of physical properties even by leaving in boiling water over a long period. CONSTITUTION:The objective water-resistant silicone rubber composition contains (A) 100 pts.wt. of a polyorganosiloxane containing alkenyl group, (B) 5-150 pts.wt. of silica powder and (C) 0.01-10 pts.wt. of a polyethylene glycol exhibiting solid state at ordinary temperature and having a hydroxyl value of 10-100 as essential components. |
