Abstract
An elastic material is provided having an elongation greater than 150% as measured according to ASTM D638-02a, a resiliency greater than 12% as measured according to ASTM D2632-01 (reapproved 2008), and a Shore A hardness of at least 10 as measured by ASTM D2240-15e1. The elastic material is an energy-cured reaction product of a curable composition that is a liquid at 25° C. The curable composition includes at least a) relatively high molecular weight (meth)acrylate-functionalized oligomer having no more than two (meth)acrylate functional groups per molecule on average; b) at least one mono(meth)acrylate-functionalized monomer having a molecular weight of less than 500 Daltons and a single (meth)acrylate functional group per molecule and/or an ethylenically unsaturated nitrogen-containing monomer; and c) at least one multi(meth)acrylate-functionalized monomer having a molecular weight of less than 1000 Daltons and at least two (meth)acrylate functional groups per molecule.
