More about Acrylic Intumescent Firestop Sealant

Acrylic intumescent firestop sealants are used to seal joints and voids in fire-rated assemblies, including around through-penetrations such as pipes, HVAC ducting, and cables. These sealants offer good adhesion to a variety of surfaces including metal, plastic, drywall, concrete, and wood. The fire-resistant and intumescent materials prevent the spread of fire and smoke by expanding to fill voids created during fires by the burning of combustible materials. Intumescent systems based on expandable graphite were found to be more common than traditional intumescent systems that require a carbon donor, phosphorous donor and nitrogen source. Most provide a four-hour fire rating for typical applications. While the primary purpose of these sealants is fire protection, they also decrease sound transmission through the sealed voids. Sealants are gunnable or can be troweled in place.
