✦ Synopsis

Abstract

Thin coats of flame‐retardant paints are unable to protect flammable substrates as there is not sufficient flame retardant in the thin coat to protect the substrate. Intumescent coatings foam and bubble when subjected to high temperatures and create multicellular cushions which prevent (a) heat from penetrating into the substrate and (b) flames from spreading along the surface. This paper concentrates on paints and varnishes, but also considers protective coatings for structural steel, smoke proof and wall piercings.

Intumescent coatings are among the most e7cient ways of 5re retarding 6ammable materials. The coatings swell under the in6uence of heat and form a thick porous charred layer. The latter perfectly insulates the substrate against an excessive increase of temperature and oxygen access. In order to make

## Abstract The aim of the study is the development of an intumescent nanocomposite coating to provide fire protection for the metallic substrate. Acrylic nanocomposites containing nanoclay and relative intumescent nanocoatings are prepared. The effect of nanoclay on the thermal degradation of an i
