Intumescent Coating

Intumescent paint cost is not the lowest comparing to other, more traditional coatings. Firstly, some intumescent coatings, especially hard char, have a low coverage rate. One litre of the coating covers 1 – 7 m² and covering one square metre can cost anything between $5 and $65. The big differences in intumescent paint cost derives from the.

Intumescent coating. Intumescent coating is a layer of protective substance which works by chemical reaction generated by heat, resulting in swelling and formation of an insulating layer on the surface, with or without release of water. This finish coat can be any color and gloss level and should be a material that will protect the intumescent coating against high humidity and other potentially harsh interior environmental conditions, while providing a smooth, attractive, architectural finish. Exterior. Application is performed through a four step, process. An intumescent system is a combination of various compounds that in the event of fire react together as a result of the temperature increase to form a carbon foam. This foam attains a thickness of 10 to 100 times of the originally applied coating and insulates the substrate material through its low thermal conductivity. A sustainable alternative for intumescent coating. You can differentiate your intumescent coating offer further by using Charmor™ Pro, an intumescent carbon donor offering the exact same high quality and technical properties as our standard Charmor™. Based on the mass balance concept, Charmor™ Pro is designed to reduce the carbon.

Intumescent firestop pillows are another common product. Most often, they are used in at data rooms because they can be packed, unpacked, and repacked as new cables are installed. The pillows are made from an insulation material like mineral fiber or mineral wool, which is then wrapped with an intumescent coating. Intumescent is a reactive coating which swells as a result of heat exposure, thus increasing in volume and decreasing in density. Specifically, an intumescent paint is a coating that reacts to heat by swelling in a controlled manner to many times its original thickness, producing a carbonaceous char formed by a large number of small bubbles that act as an insulating layer to protect the substrate. DC315 intumescent coating is an NFPA 286 tested coating designed to meet IBC/IRC Code requirements as an Interior Finish and Alternative Thermal or Ignition Barrier System over Spray Polyurethane Foam (SPF). The International Building Code (IBC) mandates SPF is separated from the interior of the building by a 15-minute thermal barrier. Adding thickness to an intumescent coating application increases the amount of swelling that will occur in the case of a fire incident. For example, if a 350 mil coating of a given intumescent has been determined to have a fire rating of 1.5 hours, 700 mils would theoretically be necessary to achieve a fire rating of 3 hours.

Pipe covered with a thin-film intumescent spray fireproofing commercial product called UniTherm. When the flame from a blow-torch is applied, the intumescent sodium silicate expands, forming a layer of insulation which slows down heat transfer to the pipe underneath. Hydrates within the coating give up their water content, maintaining a temperature near the boiling point of water, 100 °C. Intumescent coatings are opaque and visibly distinguishable when applied to the substrate. Opaque or white in color, intumescent coatings provide site-applied fire protection to various substrates in accordance with our evaluation report, ER 305 and other evaluation reports containing No-Burn ®, Inc.’s intumescent coatings. Intumescent Basecoat SC801 Intumescent Basecoat is a water-based, white, thin film, intumescent coating for the protection of internal structural steelwork. Optimised to provide up to 120 minutes fire resistance to “I” section beams, columns, hollow tube columns and cellular beams. Advantages at a glance: The intumescent coating expands at high temperatures and forms a protective, insulating layer on the surface of the steel. Therefore, in a fire, the steel structure will be protected for a given period of time while the people are safely evacuated and the fire fighters can extinguish the blaze.

Intumescent: Passive Fire Protection Supplying a number of fire safety products PFP Pipe Closers, Thermal Fire Sleeves, Fire Pillows, Duct Sleeves, PFP FR Boards, PFP Putty Pads/Cords, PFP FR Acrylic, Fire Coating & Fire Rated Mastic & more. Intumescent Coatings - Steel. The stability of a building depends on loadbearing structural steel. 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. Fire rated intumescent paint is the most commonly used coating to protect steel against fire and acts as an insulator, forming a solid char in response to heat.Intumescent paint can be applied on steel as a thin or a thick film coating. Thin film fireproof paint materials that can be used for steel are water or solved based and are typically applied to prevent fires in regular buildings. Epoxy Intumescent A self-reinforced epoxy coating, Chartek 7E simplifies application giving the oil and gas industry more choice and greater efficiency than ever before. Chartek 7E offers outstanding pool and jet fire resistance for up to two hours and a significant reduction in installed weight against other PFP products in the market.

The Intumescent Coating Systems website is a comprehensive source of information about the passive fire protection of structural steel for architect, engineers, builders and anyoneone involved in specifying and applying intumescent coatings products in Australia. The Intumescent Coating is designed to insulate the steel, and prevent the temperature of the steel from rising to a critical point at which structural failure becomes possible. Once heat is applied to these products they expand significantly and this in turn provides an insulating layer between the heat source and the substrate. Intumescent paint is a passive fire resistance coating that expands up to 50 times the original thickness when exposed to fire. A chemical reaction at about 350°F builds up an insulating char that protects the underlying material from the heat. Intumescent coating is a coating that protects the initial material by reacting to the heat exposure in a predictable, controllable manner. It reacts by swelling controllably to many times of its original thickness producing carbonaceous char or foam which acts as the insulating layer for the substrate.

Industry definitions may aid in a better understanding of what an intumescent coating (also known as fireproofing) is and is not. According to SSPC’s 2011 Protective Coatings Glossary, a fire-retardant is a “ . . . product, under accepted methods of test, that will significantly: (1) reduce the rate of flame spread on the surface of a material to which it has been applied, or (2) resist.
