Title:
シリコーンエラストマーへと架橋結合するポリ有機シロキサン一成分化合物
Document Type and Number:
Japanese Patent JP2007515537
Kind Code:
A
Abstract:
Dialkyltin dicarboxylates with oxygen atoms in the hydrocarbon part of the carboxylic acid groups, or bis-(carboxylatodialkyl)-tin oxides with optional extra oxygen atoms as defined, are used as crosslinking catalysts (C) in moisture-crosslinked, one-component silicone elastomer compositions. One-component polyorganosiloxane (POS) compositions (I) with good storage stability in the absence of moisture, which crosslink in presence of water to form elastomers. These compositions contain crosslinkable linear POS, mineral fillers and crosslinking catalysts of formula (C), in which R e>1-8C alkyl; x : 0 or 1; if x : 1, R f> = optionally unsaturated 1-20C alkyl (optionally with oxygen atoms and/or ether or ester functions); if x : 0, R f> = optionally unsaturated 1-20C heteroalkyl with one or more O atoms (and optionally with ether or ester groups) , in amounts corresponding to 0.05-0.35 mmol tin per 100 g composition (I). An independent claim is also included for elastomers which stick to various substrates and are obtained by the crosslinking and hardening of (I).
