Intumescent Paint READ MORE

London's leading and independent specialist passive fire protection contractor

SIV Fire Protection is providing expertise in all types of Built-in fire protection and passive fire protection solutions.

SIV Fire Protection offers fast, safe, cost effective and practical solution for the protection of all internal, semi – exposed and fully exposed building steel structures against fire. By applying a variety of fire rated reactive coatings, commonly known as intumescent paints, we can fire protect the steelwork for up to 2 hours.

Design and reaction of intumescent coatings

Intumescent coatings are designed to protect the structural steel sections in case of fire. Under the influence of heat, the intumescent paint reacts and forms an insulating foam layer / char barrier, which keeps the temperature of the steel below 550° C.

The intumescent coatings are based on the following system:

• Steel surface preparation
• Primer coat
• Base coat (Intumescent coat)
• Top seal

The base coat is the element of the system which reacts to the fire and consists of the following components:

• Catalyst
• Carbohydrate
• Binder
• Foaming (expanding) agent

In a fire situation, the coating will soften, and the increase of the temperature causes a chemical reaction. The catalyst decomposes into an organic acid which combines with the carbohydrate to form a carbon char. The foaming agent gives off a large volume of non-flammable gas which combines with the char to form a solid insulating layer which expands some 50-100 times than the original coat that protects the substrate.

Application of intumescent coatings

A number of important factors must be considered prior to the selection and application of intumescent coating systems. These factors are often ignored or underestimated which drove down the quality of intumescent paints’ application and significantly reduced the capability of the system in a fire situation. A poor quality workmanship can also causes extensive delamination of intumescent coating very early, within a year or two of the original application.

The application of intumescent coating systems is a specialist task and employing third party recognised contractors, certified by independent third party certification scheme is essential and strongly recommended in the Building Regulation Approved Document Part B.

SIV Fire Protection is a fully trained specialist approved contractor in the application of intumescent coating systems for the fire protection of steel structures and timber surfaces for both new construction and refurbishment projects.
