All over the world, there are several engineering and architectural works whose beauty and aesthetics are the result of a steel structure of modern and bold design. Either airports, large shopping centers, hospitals, schools, and skyscrapers, these are places that, due to their functionality, concentrate many people inside.

Capsulorhexis in intumescent cataract
Journal of Cataract and Refractive Surgery, 1999This technique of anterior capsulorhexis is for use in eyes with high intralenticular pressure and absence of red reflex as encountered in intumescent cataract. The initial steps of fashioning the anterior capsular flap and lens decompression are done under the microscope's high magnification and noncoaxial oblique illumination.

Intumescent fire-retardant systems
Polymer Degradation and Stability, 1989Abstract The use as fire retardants of intumescent systems which on heating give a swollen char is reviewed. Early developments in intumescent organic coatings are described, which provided fundamental knowledge on the chemical composition of intumescent systems.

Intumescent Reaction Mechanisms
Journal of Fire Sciences, 1985An extensive experimental program has been conducted on intumescent systems where the components have been varied systematically. Small plates were coated with the various formulations, exposed to a heat source typical of aviation fuel fires, and the temperature-time history of the substrate recorded.

One way to improve the fire performance of polymers is by the development of intumescent systems. The addition of ammonium polyphosphate/polyamide-6 is known to provide flame retardancy in many polymers via an intumescent process. The development of appropriate formulations is limited by their mechanical properties.

Flame retardants: intumescent systems
1998Intumescent fire retardant additives undergo a thermal degradation process on heating, which produces a thermally stable, foamed, multicellular residue called ‘intumescent char’. When these substances are added to a polymeric material which is later involved in a fire, they produce an intumescent char which accumulates on the surface, while the polymer

Tailored polymers: Intumescent coatings
Materials & Design, 1984Abstract Intumescent coatings, applied in the form of a paint, are dependent upon three agents within the paint formulation. The interaction of these agents results in the formation of a rigid carbonaceous foam when the paint is exposed to fire and this acts as a heat barrier.

Abstract : Formulation studies using commercial Saran microspheres and halogenated latex binder led to the development of aqueous intumescent coatings. When modified with certain flame retardant additives, compositions impart excellent flame spread resistance to wood substrates.

Intumescence‐Based Flame Retardant
2021This chapter reviews the applications of intumescence in the field of fire protection (resistance to fire) and fire retardancy (reaction to fire) of material. It starts describing the basics of intumescence and gives the main intumescent products available on the market associated with their typical application’s fields.
