Firestopping Acrylic Sealant is a single-component, water-based, gun-grade, or sprayable sealant designed to prevent the spread of smoke, fire, and toxic fumes in building penetrations and construction joints. It remains flexible, allowing for joint movement, and typically provides up to 4 hours of fire resistance.
Key Features & Description:
- Performance: Acts as a barrier for fire, smoke, and toxic gases, often with high movement capability (up to 33% or more).
- Application: Ideal for sealing through-penetrations (pipes, cables) and joints in concrete, masonry, and gypsum walls/floors.
- Material Properties: Non-sag formula, easy to apply, often paintable, and adheres well to most construction substrates.
- Types: Standard acrylic-based firestop or intumescent acrylic (which expands with extreme heat).
