Intumescent paint is used to save the building structure from passive fire. It expands to prevent the structure on which it is applied when exposed to high temperature or fire. This process not only prevents or minimizes the damage of the building but also gives enough time to the occupants to vacant the place safely.
In this article, we will discuss the process of fireproofing Intumescent paint India works to prevent the damage from fire and also how it is applied on the structures.
Let’s know the work process of intumescent paint:
Due to the endothermic reaction on the surface the intumescent paints are able to protect it. These paints absorb the heat When the temperature gets high and undergoes a chemical reaction due to which it expands or swells. A thin layer of intumescent paint coating expands upto 50 times while the normal pain only expands upto 5 times when exposed to heat. Because of the thermochemical reaction, the microporous carbonaceous foam creates that reduce heat effect on the underlying surface of the building
Intumescent paint has a unique property of active cooling effects during fire and reduces the fire effect that makes it fire proofing. Intumescent paint has hydrates that get released when it reacts at high temperature and as a result water vapour forms that cools and protects the inner subuildin
What are the materials that intumescent paint protect?
There are various materials that are protected by intumescent paint such as steel, timber, concrete, and composite. Below mentioned are the ways that it can be utilised on different materials.
Application of intumescent paints on steel materials:
Intumescent paints are always used in the constructions to protect them during fire. It is mixed with the anticorrosive primer and applied on the topcoat. This process assures me that it forms a coolness when exposed to fire forming a form. It has the ability when exposed to any exposure to heat and reduces the damage rate. The primer also helps to reduce the degradation of the instrument layer.
Before applying the compatible primer on the steel, it should make sure to clean it and also make it grease, oil, rust, dirt or any particle stick on it. Some products with which compatibles primers has been tested are Acrylic,short or medium oil alkyd, zinc- Rich epoxy(has 80% mass of metallic zinc powder or 96% mass of metallic zinc powder), zinc silicate, etc. The physical state of support is always noted while preparing the concrete and timber.
