Description
A one-part silicone sealant formulated to provide a high degree of fire resistance in a variety of joint configurations.
Features and benefits:
- Independently tested and achieves in certain joint configurations an integrity and insulation value in excess of four hours.
- Exhibits excellent unprimed adhesion to most building components.
- Suitable for sealing a wide range of construction and expansion joints in buildings, where compartmentalisation within the building is required to control spread of fire.
- It cross links at room temperature to give a flexible low modulus seal which will withstand movement of 25% in constant service throughout a wide temperature range.
- Exhibits excellent primerless adhesion to a wide range of substrates such as glass, anodized and mill finished aluminium, steel, stainless steel, PVC-U, concrete and other porous surfaces.
- Once cured, the sealant offers superb long-term resistance to heat and fire as well as all other general weather elements.
Not suitable for applications that involve traffic, submersion or food manufacture. Consult manufacturer's literature for details.
