Intumescent Acoustic Mastic - Trade Name: ASTRO INTU MASTIC
'DoP's = Declarators of Performance.
A one part intumescent acrylic mastic for sealing gaps around fire doors, window frames and for sealing joints, 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.
Maintains fire integrity when sealing around pipes and cables that penetrate walls.
Tested in Block Wall, Concrete, Masonry and Plasterboard Partition.
Tested in Concrete Floors.
Tested in Linear Joints up to 50mm 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.
Tested around metallic pipes, cable trays, cable bunches, small, medium and large cables.
Sealant remains highly flexible after installation
In normal use the mastic will maintain the sound reduction index of a structure.
The mastic has been independently tested in accordance with BS476 and EN requirements. It can provide up to 300 mins of fire resistance depending on depth/width and volumetric area - 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.

Contributes to Green Building
The fire resistance tests have been achieved through testing according to EN 1366-3, EN 1366-4 & BS 476 Part 20 & 22/1987 are specific to the conditions of test. 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.
