An electromagnetic induction instrument with a statistical function to store readings and calculate their averages is most useful. Intumescent coatings are passive fire protection measures which swell up when heated (in a fire for example) and protect the material (steel, plasterboard or wood ) underneath it, from fire. For wood, critical state is linked to the residual section of the timber load-bearing element after burning. As the coating swells it forms a carbon layer which thermally insulates the steel structure it is protecting. To determine dry film thickness (DFT) based on the wet film thickness (WTF), it is necessary to multiply the WFT by a specific number that is different from product to product. Coating steel with layers of intumescent paint can add 30, 60 or even 90 minutes extra protection from the heat. Includes Optifire+ technology - reliable and traceable fire protection
They may be based on a number of resin binders including epoxy , and silicone. Application of intumescent paint layers helps fireproof structural steel, steel beams, steelwork or cast iron and can be used externally or internally, on small or larger areas. With intumescent paint's charring reaction to fire, is there a required clearance to allow around steel member to allow for the protective charred coating to expand… Unprotected steelwork can reach temperatures of 550°C in a fire, where it then can lose its load bearing capacity and collapse. Latex/microsphere intumescent coatings show good quality and appearance when applied to wood. Further work on primer systems is needed, however, to eliminate cracking and discoloration of coatings when applied to steel panels. Intumescent coating delays the collapse of the structure through insulating the structural elements (columns, beams, floors and roofs) that support the building, thus helping achieve fire resistance levels specified in terms of time.
