Curable composition for mechanical foaming and method for manufacturing foam of the same

Abstract

Provided is a curable composition for mechanical foaming in which bubbles are evenly dispersed and bubbles do not rise to the liquid surface and from which a foam can be favorably formed when the curable composition for mechanical foaming is mechanically foamed. A curable composition for mechanical foaming having a complex viscosity η* that satisfies the following conditions (A) and (B) in frequency dependence measurement by a rheometer, in which the curing form of the curable composition for mechanical foaming is not a moisture curing form: condition (A): η* at 0.1 Hz and 25°C is in a range of 1000 to 50000 Pa·s; and condition (B): η* at 10.0 Hz and 25°C is in a range of 100 to 1000 Pa·s.
