Abstract
Abstract A one-pack type curable resin composition containing (A) an oxyalkylene base polymer having at least one silicon atom-containing group to the silicon atom of which a hydroxyl group or a hydrolyzable group is attached, (B) a filler, (C) a plasticizer, (D) a curing catalyst comprising a tetravalent tin compound, and (E) an organic carboxylic acid compound, which composition has a high curing rate after long-term storage.

Claim 1
Independent Claim
56 words
A one-pack type curable resin composition comprising (A) an oxyalkylene base polymer having at least one silicon atom-containing group to the silicon atom of which a hydroxyl group or a hydrolyzable group is attached, (B) a filler, (C) a plasticizer, (D) a curing catalyst comprising a tetravalent tin compound, and (E) an organic carboxylic acid compound.
Claim 2
Dependent Claim
167 words
The one-pack type curable resin composition according to claim 1, wherein said silicon-containing group is a group of the formula: wherein R¹ and R² are the same or different and each an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms or a triorganosiloxy group of the formula: (R')₃SiO- (II) in which R' is a monovalent hydrocarbon group having 1 to 20 carbon atoms provided that three R' groups may be the same or different; X is a hydroxyl group or a hydrolyzable group provided that when two or more X groups are present, they may be the same or different; a is 0, 1, 2 or 3; b is 0, 1 or 2 provided that b in different groups in the brackets may be the same or different; m is an integer of 0 to 19 provided that a sum of a and all b's is at least one.
