FIELD: chemistry.
SUBSTANCE: invention relates to a new intumescent coating composition. Described is an intumescent coating composition containing (a) a reaction product of tetraalkoxyorthosilicate or its partially condensed oligomer and epoxy resin containing hydroxyl groups, wherein alkoxy groups are independently selected from C1-C20-alkoxy groups, (b) one or more foaming additives and (c) one or more metal oxides and/or hydroxides. Method for protecting structures from fire or heat and substrate is also described.
EFFECT: high foam strength and high fire-resistance.
