ArmaProtect™ ABLF
ArmaProtect™ ABLF is a flexible, water-based acrylic ablative firestop filler mastic. Formulated to restore and maintain the fire resistance performance of fire-rated walls and floors, it provides an airtight and smoke-tight seal around service penetrations and structural joints.
It can be used as a standalone firestop sealant for small gaps and joints or in combination with ArmaProtect™ CB coated firestop boards to seal edges and linear gaps.
Key Features & Benefits
- Environmentally Friendly & Safe: Halogen-free, solvent-free, and low-odor formulation for safer indoor application.
- Ablative Action: Forms a protective insulating layer when exposed to heat, restricting the passage of fire, heat, and toxic gases.
- Weather & UV Resistant: Once cured, it offers durability against humidity, frost-thaw cycles, and UV exposure.
- High Flexibility: Accommodates moderate movement and thermal expansion in indoor structural connections and joint seals.
- Third-Party Certified: Fully evaluated under UL and European Technical Assessments (ETA) for high fire-resistance ratings.
