  • Patent number: 6054546
    Abstract: Provided is a solvent-free two-liquid type normal temperature curable liquid polymeric composition which comprises (I) as a first liquid, a liquid composition comprising (A) an organosiloxane component comprised of (a) one or more liquid organopolysiloxanes of the general formula: ##STR1## wherein R.sup.1 stands for a hydrogen atom, an alkyl group with 1-5 carbon atoms or an acyl group; R.sup.2 to R.sup.6 are the same or different and each stands for a hydrogen atom, --OR.sup.1 or a univalent hydrocarbon group; and n for an integer of 1-15, (b) a crosslinking agent comprising one or more organometallic compounds of the general formula:R.sup.7.sub.p M.(OR.sup.1).sub.3-porR.sup.7.sub.m Q.(OR.sup.1).sub.4-mwherein M stands for aluminum or boron element; Q for silicon, titanium or zirconium element; R.sup.1 for a hydrogen atom, an alkyl group with 1-5 carbon atoms, an acyl group or an oxime group; R.sup.7 for a hydrogen atom, --OR.sup.

  • Patent number: 5292799
    Abstract: A solvent-free, cold-setting ternary organosiloxane composition is disclosed, which contains (A) liquid organopolysiloxane, (B) a cross-linking agent, and (C) a curing catalyst, said organopolysiloxane (A) being constituted by organosilicon group of X--Si (wherein X represents a hydrogen atom or a monovalent hydrocarbyl group) and functional side chain of OR (wherein R represents a hydrogen atom, a C.sub.1 -C.sub.5 alkyl group or an acyl group), said cross-linking agent (B) being one or more organometallic compounds selected from the group consisting of an organoaluminum compound, an organoboron compound, an organosilicon compound, an organotitanium compound and an organozirconium compound having at least one functional group selected from among an alkoxy group, an acyloxy group and an oxime group, and said curing catalyst (C) being a metal-containing organic compound, with the total contents of the metal elements of the ternary composition being 40% by weight or more in terms of MO.sub.
