Notes:
An intumescnt material has been developed, based on alkali silicates, which can be used in fire protection in the form of sheets or boards which can be joined to various materials, ranging from wood and wood products to metal. The swelling of the material on heating to over 100°C or on contact with a flame is due to and endothermic process and is associated with the emission of water vapour. The solid foam formed is rigid and consists of hydrated silica. The phenomena observed during the preparation of the boards and their behaviour on heating can be explained in terms of silicate chemistry.
