Intumescent Spray Paint For Steel

Fire protection of structural steel is attained by painting the steel structures with a special protective paint an intumescent coating.

Intumescent spray paint for steel.

Product requirements will vary according to factors such as application method surface condition ambient temperature air humidity and many other factors. The cafco sprayfilm isolatek type wb product line allows designers and architects to obtain a smooth aesthetically pleasing and durable finish along with the required fire. The basic principle of intumescent coating. Intumescent is a reactive coating which swells as a result of heat exposure thus increasing in volume and decreasing in density.

The flameoff steel coverage calculator is intended to provide the user with an approximate amount of product needed for a project. The soft char intumescent coatings for steel are also known as thin film intumescents. The intumescent coating expands at high temperatures and forms a protective insulating layer on the surface of the steel. The most common use for intumescent paint in architecture is to provide an aesthetically pleasing finish on exposed structural steel members.

When exposed to high temperatures intumescent paint expands rapidly creating a protective shield around steel beams and other structural elements. Intumescent steel protection architectural fire protection for exposed structural steel in interior and exterior applications hilti fire finish 120 cfp sp wb is a high performance water based intumescent fire resistive material or ifrm for architecturally exposed structural steel in interior and exterior applications with approved top coats.

Typical spray applied fireproofing provides a thick and spongey surface that requires a finished surround to hide and protect the steel member.

Isolatek international s family of thin film water based intumescent coatings provides designers the flexibility to showcase exposed structural steel. They are lightweight coatings which when heated create a foam like char layer which is a poor conductor of heat and thus slows down the heat transfer. A compatible decorative overcoat system ensures the system will enhance the building s architectural and design features. How do the intumescent coatings work.

In the event of a fire intumescent paint helps to maintain a building s structural integrity. Thin film fireproof paint materials that can be used for steel are water or solved based and are typically applied to prevent fires in regular buildings. Fire rated intumescent paint is the most commonly used coating to protect steel against fire and acts as an insulator forming a solid char in response to heat intumescent paint can be applied on steel as a thin or a thick film coating. Specifically an intumescent paint is a coating which reacts to heat by swelling in a controlled manner to many times its original thickness to produce a carbonaceous char formed by a large number of small bubbles which acts as an insulating layer to protect the.
