Promaseal-PL is a graphite-based fire protection laminate that intumesces under pressure in the event of fire due to temperature effects. It is characterized by an early starting temperature of approximately 150° C, allowing component joints to be quickly sealed and forming a stable, solidified foam crust. This ensures a secure seal against the passage of fire and smoke gas for the entire construction. The fire protection swelling strips must be approved and released by the door manufacturer.

Technical data:

• Consistency: solid, flexible
• Fire classification: B1 flame-retardant

• Backing material: glass binding chain fabric
• Effective substance: 1.8 mm, total 2.3 mm (including PVC and self-adhesive film)
• Basis weight: 1.8 kg/m²
• Insensitive to atmospheric influences (light, heat, frost, UV radiation, moisture)
• Free from organic solvents
• Paintable with all conventional paints (preliminary tests absolutely necessary)
• Store in a cool, dry place, protect from frost and heat

Testing:

• DoP no. 13/0286
• DIBt Z-19.11-249

Application:
Excellent for wooden doors, glazing, fire protection panels, inspection flaps, facades, and construction joints in walls and ceilings.

Application instructions:
Do not overstretch the swelling strips during installation. The surface must be clean, dry, and free from adhesion-reducing influences. Carry out tests in advance to clarify whether the self-adhesive finish will achieve sufficient final strength on the substrate.
