Abstract

PURPOSE: To prepare the title sealant useful for civil engineering and construction, having excellent gas-tightness and water-tightness, and storable without oil separation, by compounding a diorganopolysiloxane having terminal OH groups bonded to Si atoms, a filler, and a silicon compound having specific group.
CONSTITUTION: A non-hardening sealant composition composed of (A) 100 parts by weight of a diorganopolysiloxane having terminal OH groups bonded to Si atoms, and having a viscosity of ≤500,000cs at 25°C, usually of the formula III (R is methyl, ethyl, etc.), (B) 1W500 parts of a filler, and (C) an organo-silicon compound having two groups selected from formula I (the left bond of the N atom bonds to Si atom) or II (the left bond of the O atom bonds to Si atom) which is bonded to Si atom and is hydrolyzable with moisture, e.g. a compound of formula IV [R1,2 are (substituted) univalent hydrocarbon group, X is I or II] or V [R, R1 and R2 are (substituted) univalent hydrocarbon group; n is an integer of 0W30; X is I or II].
