PURPOSE:To make it possible to obtain a high-strength cured rubberlike product having room temperature curability, good workability and excellent heat, water and weathering resistances, by constituting it from a saturated hydrocarbon polymer having SiOH groups and reactive silicon groups and an organic silicon polymer. CONSTITUTION:This curable resin composition is formed by mixing a saturated hydrocarbon polymer (of a number-average MW of 500-30000, desirably, 1000-15000), such as an isobutylene polymer, a hydrogenated polybutadiene polymer or an ethylene/propylene copolymer (A) having Si-bonded OH groups or hydrolyzable groups and reactive Si groups (i.e., an Si-containing group which can be crosslinked by forming siloxane bonds), for example, an isobutylene polymer having an -Si(CH3) (OCH3)2 group on each end, an organosilicon polymer (B) desirably, a liquid flowable silanol group-containing polysiloxane and a curing agent and other additives (C). |
