Abstract: Sterilization indicators include a first substrate and a second substrate. The first substrate has a compartment containing a fusible indicator material, and a channel in contact with the compartment for the molten indicator material to flow, and a wicking material in contact with the channel. The second substrate has a transparent segment aligned to overlay the wicking material. A high temperature sealing pressure sensitive adhesive layer adheres the first substrate to the second substrate. The adhesive layer includes a (meth)acrylate-based pressure sensitive adhesive matrix and a high temperature sealing agent. The high temperature sealing agent is essentially unreactive at ambient temperature but upon exposure to elevated temperatures forms a heat-sealed adhesive bond.
