Abstract
The present invention relates to an intumescent coating composition comprising (a) the reaction product of a tetra-alkoxylorthosilicate or partially condensed oligomer thereof and an epoxy resin containing hydroxyl groups, wherein the alkoxy groups are independently selected from C1-C20 alkoxy groups (b) one or more spumifics, and (c) one or more metal oxides and/or hydroxides. The intumescent coating composition provides excellent fire performance and char strength. The invention also relates to substrates coated with the intumescent coating composition, and a method of protecting structures from heat/fire.
