Unifrax engineers have expanded the Silplate® product portfolio by introducing a series of mastic coatings based on the Silplate technology. Silplate Mass S Coating combines low bio-persistent (LBP) fibres, refractory oxides and polycrystalline wool fibres with an inorganic binder system to create a wet mix. Based on its composition, Silplate Mass S is an “unclassified” material that can be applied as a hot face lining over brick, castable or edge grained fibre linings.
Once dried, this mastic provides a hard, tough armour-like shell over the surface of the substrate material. The cured Silplate Mass S surface is highly resistant to flame impingement and flue gas velocities common in industrial furnaces and kilns. At high temperatures (>1300 °C) Silplate Mass S forms magnesium silicate, creating a ceramic bond between the fibres and fillers in the material. This bond provides high physical stability to the lining surface and protects the back-up material over which it is applied.
