2140037 9402545 PCTABS00030 An intumescent composition comprises saline soluble inorganic silicate fibrous material containing CaO, MgO and no more than 4 % by weight of Al2O3, such as calcium magnesium silicate. The fibres may be vitreous, with an average length of 10 to 500 microns, and may form 5 to 30 weight percent of the composition. The composition may be incorporated in a coating composition, e.g. for wet coating (paint) or powder coating, or a mastic or putty, or a composition containing a polymer. Enhanced fire protection can be provided, and the coating compositions may be applied as a single thick coating rather than by building up thin layers.
