PROMASEAL®-GT is an intumescent fire protection laminate based on graphite that creates high pressure on expansion when exposed to high temperatures. It is characterised by an increased expansion factor and expansion pressure. It forms a stable, compact char that seals gaps or openings quickly. This ensures a secure seal against the spread of smoke and fire of the overall construction.
