Curable compositions, articles therefrom, and methods of making and using same

Abstract

A curable composition includes a first part comprising an epoxy resin; and a second part comprising a multifunctional, functional thiol containing compound. The curable composition further includes an inorganic filler present in an amount of at least 20 weight %, based on the total weight of the curable composition. The multifunctional, functional thiol containing compound comprises an ether in the backbone thereof.
