Fire Retardant Paintable Sealant

Fire Retardant Paintable Sealant AS-1001

Fire Retardant Sealant is a one-component, high-performance, acrylic-based fire-resistant sealant that provides flexibility in fire-resistant joints. It has 4 hours of fire resistance in accordance with BS EN 1366-4: 2006. The product is almost odorless and non-corrosive to metals. After application, the product forms a tough flexible elastic rubber by evaporation of water from the sealant.

Joint Design

• The specified sealant bead size should be calculated to comply with the compression and extension capabilities of the sealant in relation to the anticipated joint width due to expansion and contraction.
•  The minimum bead size should not be less than 3 mm to accommodate movement.
•  Sealant design joint width-to-depth ratio should be 2:1.
