摘要：
A layered insulation panel including a rigid polyisocyanurate foam layer and, adhered to at least one surface thereof, a facing material. The two materials are adhered by a two-component polyisocyanurate adhesive, and both the polyisocyanurate adhesive and the polyisocyanurate foam layer undergo polymerization concurrently and in place. The result is that the tensile bond strength between the polyisocyanurate foam layer and the facing surface is improved, due to interaction between the polymerization occurring at the surface of the foam layer and the polymerization of the polyisocyanurate adhesive.
