Elastomer system obtained by crosslinking a composition including: - (A) 100 parts by weight of an alpha , omega -di(hydroxy)diorganopolysiloxane; - (B) from 2 to 20 parts by weight of a crosslinking silane containing a hydrolysable group; - (C) from 0 to 150 parts by weight of inorganic or organic fillers; - (D) from 1 to 150 parts by weight per 100 parts of A + B + C of a solid inorganic or organic compound capable of releasing active chlorine in contact with water or moisture (preferably calcium hypochlorite); - (E) optionally a catalyst of crosslinking by polycondensation; the said composition containing at least 0.01 % of its weight of water, added and optionally generated intrinsically and optionally added extrinsically. Use of the said system as agent for releasing active chlorine, especially for water treatment. |
