Patent ID: 8702832

Claim:
A securable mounting material comprising: a mounting material comprising inorganic fibers and having first and second opposed major surfaces; and a dry layer of a thermally activatable adhesive inwardly disposed on the inorganic fibers of the mounting material proximate at least a portion of the first major surface, but not extending throughout the entirety of mounting material; wherein, on a dry weight basis, at least one compound represented by the formula (M m+ ) d ((Z p O q (OH) r ) n− ) e .(H 2 O) f comprises a majority of the thermally activatable adhesive, and wherein each M m+ independently represents a cationic species, other than H + , having a positive charge of m+; and (Z p O q (OH) r ) n− represents a species having a charge of n−, wherein Z represents boron, and further wherein: f is a real number greater than or equal to zero; d, n, q, and r are integers greater than or equal to zero; e, m, and p are integers greater than or equal to one; and d times m equals e times n; and wherein the securable mounting material is flexible, and wherein the mounting material further comprises an unexpanded intumescent material.
