Bindex fire and acoustic sealant

Bindex fire and acoustic sealant is an acrylic based sealant designed to stop sound, smoke and fire from passing through gaps in fire rated walls and ceilings. It has been fire tested in Australia for control joints, perimeter seals and penetration seals around cables and metal pipes.

When it is exposed to heat, it forms a fire barrier by expanding and forming a solid charred material. It provides fire performance of up to 3 hours in plasterboard walls whilst maintaining the acoustic rating of Siniat wall and ceiling systems.

The acrylic formulation means water wash up, easier application, a paintable surface and low volatile chemical content for a low odour product.

Applications:

Surfaces must be clean and free from dirt and grease. Use a brush to remove loose material.
Lightly apply water or diluted Bindex to porous materials to improve bonding. The surfaces may be damp but not running wet.
For the best bond, overlap Bindex onto the material surfaces. The application range is in temperatures between +5 °C and +40 °C.

Single layer butt joints and multi-layer recessed and butt joints can be jointed with bindex fire sealant and maintain the fire rating of Siniat wall systems. A bead of sealant is applied along the edge of a face layer sheet of plasterboard, then the next sheet is butted up against the first sheet. Sealant must squeeze out of the joint. Excess sealant may be scraped off or left as is. Single layer butt joints must be backed with framing. Bindex fire and acoustic sealant can be used instead of Mastabase and paper tape to joint sheets in multi-layer systems.
