Abstract
A composite barrier material is disclosed. The barrier material includes a first layer including a polymer resin in an amount of at least 40% by weight of the first layer and defining a first matrix, and a second layer integrally bonded to the first layer and including a polymer resin in an amount of at least 40% by weight of the second layer and defining a second matrix. The polymer resin of the first matrix has a different chemical structure than the polymer resin of the second matrix and the second layer has a cured hardness greater than the first layer. The shear bond strength of the barrier material is at least equal to the shear bond strength of a similar single matrix laminate comprising first and second layers of the same matrix material.
