Intumescent paint for steel uk. An overview of intumescent paint products and manufacturers in the uk whatever you fire category or building regulation requirements, there is an intumescent paint for your needs. The intumescent coatings are based on the following system: Intumescent steel paints and coatings are available in water and solvent based forms, providing protection to most structural steel sizes of 30, 60, 90 and 120 minutes fire protection, utilising thick and thin film intumescent coating technology.
Incorrectly applied intumescent paint delaminating from a structural steel member. Conforms to bs476 part 21. Intumescent paints are specialist coatings that provide up to 120 minutes fire protection on structural steel.
This increase in volume and decrease in density provides insulation to the structural steel members against high. Fire and intumescent paints our range of fire and intumescent paints is extensive and comes from some of the leading brands in the industry. As one of the largest intumescent paint suppliers in the uk we supply for projects large or small, from factories, warehouses and hotels to a single beam or rsj for a home extension or house or flat loft conversion.
Intumescent coatings are designed to protect the structural steel sections in case of fire. Intumescent coating products are designed to passively protect substrate materials—typically steel—from reaching combustion temperatures. Intumescent paint, insulates structural steel and cast iron steel during a fire, keeping components below the critical (collapse) temperature.
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. A compatible decorative overcoat system ensures the system will enhance the building’s architectural and design features. Fireproof coatings, intumescent paint, wallpaper and sprays compatible with a range of materials.
The top international manufacturers like akzonobel, ppg, jotun, and sika all sell their products on the uk market, and provide them to local approved contractors. The paint reacts to high temperatures, typically above 200 c, by expanding up to 50 times its original thickness. The base coat is the element.
With top coats, base coats and acrylics and matts available in a wide variety of colours, you can achieve the aesthetic appeal you are looking for at the same time as increasing the level of protection in. Our intumescent coatings have been exhaustively tested both in our own laboratories but also to national and international standards in independent test houses across the globe. Brush, roller or airless spray application.
Fire resistance for load bearing elements of structure. Intumescent paint for structural steel and cast iron. Nullifire intumescent coatings for structural steel, are the tried and tested way of protecting buildings and people from fire.
In the case of an intumescent paint, when subjected to temperatures exceeding 120°c the paint will intumesce (swell up to 50 times the thickness of the paint) and form an carbon layer (char) which, in the case of intumescent steel paint, thermally insulates the steel substrate and maintain a temperature below 550°c or 620°c for a given. For this reason, a coating thickness gauge with a high measurement range is required. Our fn max paint thickness gauge has a very high upper measurement limit of 5,000µm (5mm) on ferrous metals, such as steel.
Intumescent paint tends to be applied as a thicker coating than many other types of painted coating, such as automotive paints. These coatings function by charring and “swelling” upon exposure to high temperatures such as when a fire occurs. Passive fire protection materials insulate steel structures from the effects of the high temperatures that may be generated in fire.
In order to fulfil the requirements of building regulations (to maintain the building’s stability for a reasonable period), the load. A compatible decorative overcoat system ensures the system will enhance the building‚äôs architectural and design features. Water based intumescent for structural steel.
However, there are some products that are not available to purchase online, owing to the need to verify that the products are being applied correctly. A compatible decorative overcoat system ensures the system will enhance the building’s architectural and design.
