Idealseal Intumescent is a premium fire rated acrylic sealant specially formulated for fire sealing. It is easy to apply with strong adhesion to various surfaces and cures to form a durable, flexible, paintable seal accommodating joint movement of ±12.5%. Thermal activation takes place at temperatures above 125°C when the seal will expand and form a robust char coat to restrict the passage of fire, smoke, and gas for up to 4 hours (see tables for further information). In addition, it offers excellent sound insulation.
USES
Idealseal Intumescent is designed to prevent the spread of fire and smoke through joints and openings up to 35mm in fire rated walls, partitions, ductwork, doors, windows, and floors including openings formed around building service penetrations. It will also maintain the acoustic design performance in walls and floors. Suitable for most surfaces, including concrete, masonry, steel, gypsum board, plastics, and most non-porous surfaces.
APPLICATION
Surfaces must be clean, dry and dust free. Cut the cartridge seal and screw on nozzle which should be cut to required size. Gun the sealant firmly into joint ensuring no air is trapped behind. Tool with a spatula wetted whilst acrylic is still wet. If required place masking tape along joint edges, removing within 10 minutes of application.
