Bindex Fire & Acoustic Sealant is a heavy-duty acrylic sealant engineered specifically for Australian Siniat wall and ceiling systems. It acts as a permanent barrier against fire, smoke, and noise, ensuring your work meets building codes and provides peace of mind for the client.
Features:
- Serious Fire Protection: When things get hot, this sealant expands (intumescent) to form a solid char barrier. It’s tested to achieve up to a 3-hour fire rating on plasterboard walls.
- Better Soundproofing: Stops noise from “bleeding” through gaps, which is essential for multi-res units, offices, and acoustic privacy.
- Easy to Work With: Unlike messy industrial sealants, Bindex is a low-slump acrylic. It’s easy to gun out, easy to tool off, and offers water wash-up.
- Safe for Indoor Use: It has a low-odour, low-VOC formula, making it much better for your lungs when working in tight, indoor spaces.
- Paintable Finish: Once cured, it can be painted over to match the wall for a clean, professional look.
Applications:
- Control Joints & Perimeter Seals: Sealing the edges where walls meet floors or ceilings.
- Penetrations: Filling gaps around electrical cables and metal pipes.
- Plasterboard Jointing: Can be used instead of standard base coat and tape in multi-layer systems to maintain fire integrity.
