Product Description Thermoguard Thermocoat S is a intumescent solvent-borne coating for the protection of exterior steels and steels exposed during construction. When applied in accordance with the correct film thickness schedule can achieve 30, 60, 90 and 120 minute protection. Thermocoat is an intumescent paint system providing fire resistance to structural steel and cast iron of up to 90 mins with a minimum number of coats. A compatible decorative overcoat system ensures the system will enhance the building’s architectural and design features. Recomended for external exposed steel not subject to pooling water. How do intumescent coatings work? The heat of a fire triggers a catalytic reaction, causing the expansion of an insulating char layer up to 50 times the paint thickness. This layer keeps the steel below its critical temperature, thus maintaining the structural integrity of the building. Please Note: If certification is required, an intumescent enquiry form must be completed prior to purchase of the product, as this will ensure the correct quantity is applied to achieve the fire rating. The enquiry form is available to download from the ‘Data Sheets’ tab. Thermocoat S Application Thermocoat S may be applied by brush, roller or airless spray. To achieve the best finish in the shortest time, spray application is recommended. Prior to application the contractor should contact Thermoguard’s Technical Department and obtain a basecoat application schedule. To assist correct application in accordance with this schedule, a wet film gauge will be supplied with the order. Further wet film gauges will be provided on request.
