Abstract

A composite adhesive fire barrier comprises a fire barrier material having first and second opposed major surfaces and a pressure-sensitive adhesive layer disposed on the first major surface of the fire barrier material. The fire barrier material comprises inorganic fibers and has an inorganic component content of at least 50 percent by weight. The pressure-sensitive adhesive layer comprises a crosslinked mixture of a silicone having a kinematic viscosity of at least 30,000 centistokes and an MQ silicate tackifying resin disposed on the fire barrier material. The silicone and the MQ silicate tackifying resin are present in a respective weight ratio of 4:1 to 20:1. A release liner comprising a fluorinated compound is releasably adhered to the pressure-sensitive adhesive layer. Methods of making and using the composite adhesive fire barrier are also disclosed.
