Description

A one part intumescent acrylic mastic for sealing gaps around fire doors, linear joints, penetraction 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.

Maintains fire integrity when sealing around pipes and cables that penetrate walls.

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.

Tested around metallic pipes, cable trays, cable bunches, small, medium and large cables.

Sealant remains 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.

** Insulation In Floor Reduces 50% , However Integrity Remains the Same **

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.
