摘要： An organic silicon compound represented by formula (1) makes it possible to significantly lower the hysteresis loss of a cured product when added to a rubber composition and also imparts a rubber composition with which it is possible to realize a desired low-fuel-consumption tire. (In the formula, R1 independently represent a C1-10 alkyl group or C6-10 aryl group, R2 independently represent a C1-10 alkyl group or C6-10 aryl group, f represents a number of 0 or higher, e and g independently represent a number greater than 0, and m represents an integer of 1-3. However, the order of each of the repeating units is arbitrary.)

摘要： The present invention is a room temperature curable resin composition comprising: as the main agent, an organic polymer in which both molecular chain terminals are sealed by a silanol group and/or a hydrolyzable silyl group; and an organic silicon compound of a specific structure having, in a molecule, an organosiloxane structure, a hydrolyzable silyl group, and a hindered amine skeleton. This resin composition produces a cured product in which the degradation over time associated with the effects of light such as UV rays can be suppressed.
