Title:
CURABLE COMPOSITION AND ADHESIVE
Document Type and Number:
WIPO Patent Application WO/2017/179536
Kind Code:
A1
Abstract:
A curable composition which contains 100 parts by mass of (A) a flexible epoxy resin, 1-150 parts by mass of (B) polymer fine particles, each having a core-shell structure having at least two layers that are a core layer and a shell layer, and 1-200 parts by mass of (C) an epoxy curing agent, and which is characterized in that: the glass transition temperature (Tg) of the core layers of the polymer fine particles (B) as calculated by mathematical formula (1) is higher than 0°C; and the type A durometer hardness as prescribed in JIS K6253-3 of a cured product that is obtained by curing this curable composition is 5-95 at 23°C.
1/Tg = Σ(Mi/Tgi) (1)
(In the formula, Mi represents the weight fraction of a monomer i component selected from among butadiene and non-crosslinkable monomers constituting the core layers of the polymer fine particles (B); and Tgi represents the glass transition temperature (K) of a homopolymer of the monomer i.)
