QuelStop HPE Sealant | QHPE
Description
Description
QuelStop HPE Intumescent Graphite Sealant is a high-expansion, intumescent, acrylic-based sealant containing graphite, designed to reinstate and maintain the fire rating of walls and floors where service penetrations occur.
On exposure to heat, it expands significantly to seal gaps and prevent the spread of fire. It can be used as part of the QuelStop Fire Batt System or applied directly to the substrate for effective firestopping, depending on the tested application*.
Each box contains 25 tubes, so we recommend ordering in multiples of 25 for convenience. However, individual tubes can also be supplied if required.
*This is general guidance only. Always check the tested details to ensure you are installing a compliant solution.
Standards & Approvals
Standards & Approvals
QuelStop CE Marked HPE Graphite Sealant may be used for sealing around services such as cable, cable bundles, trays, ladders, combustible pipes, combustible insulations, either as part of a seal directly within the wall or floor substrate or as part of a QuelStop Fire Batt Seal.
All surfaces must be clean and free of any bond breaking contamination prior to application of the sealant.
The sealant should not be applied if the ambient temperature is below 5°C or above 35°C, as the adhesion may be impaired.
The QuelStop Intumescent HPE Graphite Sealant should be installed to the correct annulus and depth which depends on the penetrating services / material specification. The total annular space should be filled with compacted QuelStop HPE Sealant which is applied through the use of a standard sealant gun and once applied should be lightly compacted and smoothed off with a spatula to produce a professional and neat finish.
For full details on application and installation, refer to all available documentation, installation details and the Quelfire Technical team.
*Please note that custom made items can expect to have longer lead times. Next working day is typical but can depend on outside factors not controlled by Quelfire.
