The present teachings relate generally to a one part room temperature curable composition. e.g., a one-part epoxy-based adhesive precursor composition. The composition may include an epoxy resin, and a filler. The composition may include a flame retardant sufficient so that when the adhesive precursor composition is cored, it meets applicable requirements for flame retardancy of 14 C.F.R. § 25.853 for aircraft inferior cabins. An amount of a curing agent may be included. The selection of the epoxy resin, curing agent, or both, may afford curing with or without the need for an application of heat. The epoxy resin, the filler, any flame retardant and the curing agent are admixed to define a substantially homogenous admixture, thereby defining a mass of adhesive precursor.
