Description
A one part intumescent acrylic mastic for sealing gaps around fire doors, linear joints, penetration seals, voids and irregular holes in fire rated structures. The sealant forms a char, preventing the passage of fire and smoke, when exposed to the heat of a fire.
Tested around metallic pipes, cable trays, cable bunches, small, medium and large cables.
Tested in Block Wall, Concrete, Masonry and Plasterboard Partition.
Suitable for flexible walls, rigid walls & floors.
Tested in Linear Joints up to 60mm wide.
Tested in large service openings up to 490 x 150mm.
Tested for sealing of linear joints in concrete floors, masonry walls and plasterboard including head of wall details up to 60mm.
Sealant remains flexible after installation
The mastic has been independently tested in accordance with BS476 and EN requirements - please refer to the Performance Table below.
It has good unprimed adhesion to a wide variety of common building substrates. although we do recommend that a small area is tested on unusual substrates.

The fire resistance tests have been achieved through testing in according to EN 1366-3 : 2009 and EN 1366-4 : 2006 and are specific to the conditions of the tests. They do, however, provide a good indication of the expected performance of the sealant in fire situations. To achieve a specific fire rating, all substrates being used in the system must have equivalent fire ratings.

Installation
We have technical representatives who provide assistance in the selection and specification of the products on this site and should be consulted for exact installation and product suitability. Ensure an early engagement with ourselves, designers, main contractor and specialist installers before any installation. Other trades and/or manufacturers may need to be consulted. For in-depth information, specification and technical advice please call our Head Office on:
Telephone: +44 (0)1329 844 500
Email: sales@astroflame.com
Maintenance
All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 – Code of Practice for the Installation and Inspection of Fire Stopping.
Competency
It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
Health and Safety
The product does not present any known health hazards during or after installation. Normal good industrial and personal hygiene practices should be observed. For further information on health and safety requirements please contact the technical team on:
