FR Coating is a spray grade ablative sealant coating designed to enhance, seal and fire protect mineral fibres. It is based on a durable polymer system with inert fillers, non-halogenated fire retardants and a preservative to resist microbial attack.
FR Coating is designed to be applied by spraying directly onto mineral fibres. The coating dries to give a sound and flexible white surface finish. During installation of mineral fibres, the cured sealant coating reduces de-lamination and increases the surface stability for adhesive and fixing sealant application.
The ablative property of the coating resists flame spread and protects the mineral fibres against fire penetration by significantly reducing the permeability of the mineral fibre core and prevents the passage of hot gases. This reduces the temperature rise on the unexposed side and reducing heat conduction through the building services.
Mineral fibres coated with FR Coating are designed to prevent the spread of fire and smoke through opening in fire rated walls and floors and where openings are formed to allow the installation of multiple building services. The system will also maintain the acoustic design performance.
