The thickness of intumescent that should be applied on a structural steel section depends on the required protection time but also the characteristics of the steel section. For calculation of DFT (dry film thickness) a factor called HP/A (heated perimeter divided by cross sectional area) is used. temperature and coating-thickness expansion. Intumescent paint provides the same level of protection in a coating that looks like a thin layer of paint. Free Delivery Over £900; Quality Guarantee; Call us on 01392 822600; Track Your Order. Shelf Life 3M TMFireDam Intumescent Coating WB 1000 shelf life is 6 months in original unopened containers from date of packaging when stored above 10oC (50oF). intumescent coatings are designed for internal use and typically have a dry film thickness no grater than 5 mm. , beam, column, angle, etc. Each product available at Rawlins Paints comes with an in-depth datasheet, outlining application methods, drying time and layer specifications before the top, pigmented to colour. coating for a composite laminate of a defined thickness. Intumescent (reactive) coatings are coatings that react under the influence of fire and swell in a controlled manner to many times their original thickness, producing an insulating carbonaceous char or foam that protects the substrate from the effects of the fire. The thickness of this intumescent coating is dependent on the steel section used. the protection - up to a limit. Also note there should be a distinction made between what I'm calling intumescent coatings and what I will call intumescent paint. 1 Chart for Thickness for Target Performance Performance Level in CAN/ULC-S9705 Test(1) Equivalence Primer Thickness(2) (wet film thickness [WFT]) DC 315 Thickness (WFT) 10 min. Faster results recognised. No asbestos ingredient:. specializes in protecting surfaces and structures from corrosion with high-performance coatings and linings. An intumescent formulation comprises a clay such as an organoclay, a source of carbon, a blowing agent and an acid source. Surfaces to receive intumescent coating shall be cleaned prior to the application of the fireproofing. ALBI CLAD 800 Product Data Information page 1 of 2 Albi Clad 800 is an intumescent mastic coating applied to structural steel, concrete and other construction materials for the purposes of fire protection. The mastic and intumescent coating average thickness should not exceed the maximum thickness published in the individual designs and no individual thickness measurement should be less than 80% of the thickness specified in a design. 60 mils per coat By. Intumescent paint – This fire rated paint expands in the presence of fire, swelling to up to 50 times its original thickness and forming a foam-like char which is very slow burning. Paint-Thickness.
