Protecta FR Graphite 4hr Intumescent Sealant, part of the Protecta Firestopping range, a high specification formulation designed to prevent the spread of fire, smoke and gases through openings in fire rated walls and floors. Protecta FR Graphite expands when it is subjected to fire and closes openings around penetrations when any combustible or low temperature melting materials have burnt away, designed to fire seal difficult services which traditional fire rated mastics do not achieve such as large plastic pipes.

Protecta FR Graphite can be used with a suitable filling material, i.e. stone wool or Protecta Backing material in order to ensure correct width to depth ratio and to reduce the shrinking of the sealant during curing. Minimum depth and maximum width of the joints are included in the installation instructions. Thermal activation takes place at 150°C when the material will expand (intumesce) to prevent the passage of fire and smoke for periods up to 4 hours.

NEW - Eco-Foil System

The system works by inserting a 300ml foil into the reusable Eco-Cartridge, which fits into a standard skeleton gun. The cartridge has a double-ended plunger, so once the foil is empty, remove the cap and nozzle and re-fill the opposite end with a new 300ml foil. Simply replace the cap and nozzle at the opposite end, insert into the dedicated foil gun and the system is ready for use!

• One Eco-Cartridge can be reused a minimum of 60 times
• Reduces on-site waste by more than 90%
• The system fits into a standard skeleton gun
• 6 months longer shelf life than the same product in a cartridge

Installation

Refer to the Application Guide for illustrations and more detailed drawings for the following fittings:

• Plastic pipes in drywalls, masonry or concrete walls (pages 2-3)
• Plastic conduits in drywalls, masonry or concrete walls (page 3)
• Cables and cable trays in masonry or concrete walls (page 3)
• Plastic pipes in masonry or concrete walls (pages 3-4)
• Insulated steel pipes in floors (page 4)
• Plastic pipes in floors (pages 4-6)
• Plastic conduits in floors (page 6)

For fire sealing additional pipes and classifications, please refer to Protecta FR Collar’s Technical Data Sheet and Installation Instructions.

Minimum separations and limitations:

Services can be sealed as specified in the detailed drawings. Minimum separation between services and the edge of the seal within each aperture must be 10 mm to allow for correct fitting of backing and seal depth. Minimum separation between apertures should be at least 30 mm. For larger apertures other than described in the detailed drawings, Protecta FR Board or EX Mortar should be used.

Supporting constructions:

Flexible walls must have a minimum thickness of 100 mm and comprise steel studs or timber studs***) lined on both faces with minimum 2 layers of 12.5 mm thick boards. Rigid walls must have a minimum thickness of 100 mm and comprise concrete, aerated concrete or masonry, with a minimum density of 650 kg/m³. Rigid floors must have a minimum thickness of 150 mm and comprise aerated concrete or concrete with a minimum density of 650 kg/m³. The supporting construction must be classified in accordance with EN 13501-2 for the required fire resistance period.

*** Timber studs: no part of the penetration seal may be closer than 100 mm to a stud, and minimum 100 mm of insulation of class A1 or A2 according to EN 13501-1 must be provided within the cavity between the penetration seal and the stud.

1. Before installing Protecta FR Graphite ensure that the surface of all service penetrations and surrounding construction is free from all loose contaminants, dust and grease.
2. As Protecta FR Graphite is water based, in cases where corrosion protection is a problem; some metals may require a barrier between the sealant and the metal surface prior to this installation.
3. When installing any backing material, cut this slightly oversize and insert into the gap ensuring a tight friction fit. Ensure correct depth is achieved.
4. Fill the gap or joint with Protecta FR Graphite to the required depth. Refer to the drawings on following pages 2 to 6 for guidance on joint design/dimensions.
5. Apply the sealant generously avoiding air bubbles. Finish the bead with a moist spatula or pallet knife. Avoid excessive tooling/smoothing as this may make the seal surface wet and soft.
6. Protecta FR Graphite can be over-painted with most emulsion or alkyd (gloss) paints.

Test Standards

This Installation Instruction is based on the product’s European Technical Assessment issued in accordance with regulation (EU) No 305/2011 on the basis of EAD 350454-00-1104, September 2017.

Sound Insulation

Protecta FR Graphite has been tested at EXOVA BM Trada (UKAS accredited); according to EN ISO 10140-2:2010. Usage of any backing material is optional, due to the tests being conducted with sealant only.

Emission data (indoor air quality)

Protecta FR Graphite complies with the requirements of GEV and the results correspond to the EMICODE emission class EC 1PLUS which is the best possible environmental and indoor hygiene health protection mark. Tested by Eurofins Product Testing, report number G12871B.

Pipe End Configurations

When testing pipes, one can choose not to cap (or close) the pipe, or cap the pipe inside the furnace, or outside the furnace, or on both sides. The configuration chosen depends on the intended application of the pipe and/or the installation environment. The code defining if a pipe is capped is stated after the fire classification. For instance EI 60 C/U which means the pipe was capped inside the furnace, and uncapped outside the furnace. The test configuration defines the approvals possible.

Our engineering judgment based on EN 1366-3:2009 are:

Notes:

1. Stated in EN 1366-3:2009
2. Polyseam’ s judgment based on tests
3. Metal pipes should have fire rated support
4. U/U classified fire seals cover C/U, U/C and C/C. C/U classified fire seals cover U/C and C/C. U/C classified fire seals cover C/C
