Protecta FR Adhesive
Protecta® FR Adhesive is a ready-to-use, water-based thixotropic paste formulated with an inorganic polymer and filler. Designed to withstand extreme temperatures exceeding 1,200°C, it delivers excellent early grab and rapid bond strength. Upon curing, it forms a robust, cement-like bond with long-term adhesion, making it ideal for bonding and sealing in high-temperature or fire-exposed environments. It serves dual functions as both an adhesive and a filler, suitable for a wide range of construction, mechanical, and industrial applications requiring fire resistance.
Note: Not tested to AS1530.4-2014 and AS4072.1-2005.
