B-staging is a process that utilizes heat or UV light to remove the majority of solvent from an adhesive, thereby allowing a construction to be “staged”. In between adhesive application, assembly and curing, the product can be held for a period of time, without sacrificing performance.

A B-stage adhesive is a single component adhesive system that partially cures during an initial stage, then completely cures at a later time under heat and pressure. High performance adhesives and epoxies can be formulated as B-stage systems which are initially in a partially cured stage. When reheated to an elevated temperature, cross-linking completes and the substrate completely cures.
