FAS0133 FR Intumescent Sealant is a halogen free, polymer emulsion-based sealant that swells when subjected to temperatures in excess of 125°C and forms a char coat that restricts the passage of smoke and fire. It is easily applied and dries to a flexible and smooth surfaced material which is readily over paintable. It has excellent adhesion to a wide range of substrates and will not harden or crack with age.
Specification Compliance
FAS0133 Intumescent FR Sealant has been independently tested to the following assessments:
- BS EN 1366-3: 2004 & BS EN 1366-4: 2006 Tested at Bodycote Warrington Fire, achieving 4-hour integrity and insulation rating for a range of linear and penetration seals.
- an indicative fire test based on BS476 Part 20 & 22 at Warrington Fire Research and achieved a 4- hour fire rating (integrity) for a range of vertical and horizontal joints up to 35mm wide between various non-combustible construction materials. A 1-hour fire rating (integrity) was achieved for a range of vertical joints up to 25mm wide between combustible materials (timber).
- BS EN ISO 10140-2: 2010 Measurement of Airborne Sound Insulation of Building elements. University of Salford reports 2612 – 76, 77, 79 – 81. The sealant maintained the integrity of a plasterboard partition wall with a Sound Reduction Index of 55Db. VOC test report classification – M1 and Indoor Air Comfort GOLD ®
Applications
FAS0133 Intumescent FR Sealant forms a fire and smoke seal in joints up to 35mm wide without slumping. It is ideal for sealing joints in and around internal partitions, lap joints in fire-rated cladding and for sealing between fire doors and fire-rated walls. It is recommended that a sealant depth of at least 8 mm be applied.
If the sealant is to be overpainted, building regulations may require a fire-resistant coating.
Limitations
FAS0133 Intumescent FR Sealant is not suitable in joints where movement exceeds ± 7.5% of joint width, or in external joints.
Applications Instructions
To achieve a high-quality joint, clean all surfaces, remove dust and ensure surfaces are dry. Non- porous surfaces should be degreased using a suitable degreasing agent. Highly porous surfaces should be sealed with a suitable primer. Apply masking tape to each side of joint and gun sealant firmly into joint, smoothing off with a wetted spatula. Masking tape should be removed within 10 minutes of application.
Coverage
1 tube is sufficient to produce approx. 1m using a 20mm x 15mm bead.
Storage
Store in cool dry conditions. PROTECT FROM FROST.
