摘要:
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.1 or a univalent hydrocarbon group; p for an integer of 1 or 2; and m for an integer of 1-3, and (c) a curing catalyst which is one or more organometallic compounds of zinc, cobalt, aluminum or tin element and has been incorporated with a catalytic reaction blocking agent, and (B) an organosiloxane carrying a glycidyl group, and (II) as a second liquid, (C) a solvent-free acrylic copolymer carrying a tertiary amino group which has been adjusted in viscosity with a silicone. This composition is excellent in various physicochemical characteristics and is very suitable for use in paints and binders.
摘要:
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.y/2 (wherein M represents aluminum, boron, silicon, titanium or zirconium, and y represents a valency of the metal element). A transparent film, a coating material, a binder and a structure formed by using same are also disclosed.
