The project is in Seattle WA.The spec is for Hilti Fire Finish 120+ CFP-SP WB Steel loses its loadbearing capacity when its temperature rises above 550ºC during a fire; therefore structural steel protection with intumescent coatings is required to preserve the stability of the building structure in the event of a fire. Steel and Gypsum CDWZ.R38327. The intumescent coating products listed on this page are available for interior and exterior use and come in a full range of colours, with full product descriptions available on each item. In the event of a fire the coating will 'intumesce' and expand to form a thermally insulating layer of char to protect the steel beneath… read more The purpose of intumescent products is the prevention of the structural collapse of the building, which can occur if load- bearing steel elements reach a critical state. Exposure to the heat of a fire triggers a reaction, causing the intumescent paint to expand to up to 50 times its thickness and form a solid foam-like char. Found inside – Page 119In airconditioned areas and other places where false ceilings etc. are provided , automatically screens the steel ... 4.10.5 Intumescent Coating Materials which can be painted on the surface of steel and which gets converted into high ... Intumescent coatings protect steel from getting too hot by swelling and charring in the event of a fire, becoming an insulating layer for the metal substrate. Thin film intumescent coatings usually require a primer to be applied to the steel first and sealer topcoat to finish the system to offer between 30 and 90-minutes fire resistance. Found inside – Page 48Intumescent coatings, while giving the impression of a painted finish, are thicker than paint and have a textured finish. The required thickness varies with the level of fire protection as well as the thickness of the steel. The main chemical families of topcoats used for environmental protection are: Intumescent paints can also be used for protecting concrete, in which case the thickness necessary for the given fire resistance time is calculated with regard to the critical temperature of both the steel reinforced bars (between 350 °C and 500 °C) and the concrete cover (the least distance between the surface of embedded reinforcement and the outer surface of the concrete). For wood, critical state is linked to the residual section of the timber load-bearing element after burning. Must be clean, dry and free from dust, oil, loose mill scale or rust, and any other condition preventing good adhesion and blast cleaned in accordance with proper international standards. Intumescent- SYNTHOMER Home | Region: EMEA © Copyright 2021 Rawlins Paints.

"Intumescent" means swelling, particularly when exposed to heat, and describes the reaction that intumescent paint undergoes in a fire. The dry film thickness and quantity of material required for a certain fire resistance time (R 30, 60, 90, 120 minutes or more) depends upon various factors. Intumescent paints for steel, structural steel and cast iron at Rawlins Paints are available with 30, 60, 90 and 120-minute fire protection, to accompany fire retardant paints for other surfaces, available here. Found inside – Page 180Fire-resistive coating or intumescent coating may be applied at an appropriate thickness. The required thickness of insulation for a structural steel member may be determined by using a nomogram which relates critical temperature, ... Unprotected steelwork can reach temperatures of 550°C in a fire, where it then can lose its load bearing capacity and collapse. Extending crucial evacuation time. Following the sufficient period of drying, a survey of dry film thickness should be carried out using a suitable calibrated gauge. Fire protection for up to 120 minutes.
