<p>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: <CHEM> wherein R<1> stands for a hydrogen atom, an alkyl group with 1-5 carbon atoms or an acyl group; R<2> to R<6> are the same or different and each stands for a hydrogen atom, -OR<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<7>pM.(OR<1>)3-p or R<7>mQ.(OR<1>)4-m wherein M stands for aluminum or boron element; Q for silicon, titanium or zirconium element; R<1> for a hydrogen atom, an alkyl group with 1-5 carbon atoms, an acyl group or an oxime group; R<7> for a hydrogen atom, -OR<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 ( @ ) 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.</p> |
