Abesco CP310 FR Acrylic Intumescent Caulk

The Abesco CP310 FR Acrylic Intumescent Caulk, which has been tested according to ASTM E814 (UL1479) and achieved a UL Classified 2-hour rating, is a water-based caulk designed to fill gaps and cracks in walls and ceilings. This environmentally friendly, halogen-free caulk adheres to most building substrates and expands when exposed to fire, forming a carbonaceous char that effectively blocks smoke and fire from passing through. Additionally, the acrylic intumescent caulk does not contain any solvents, PCBs, or asbestos, making it a safe and reliable choice for fire protection.
