Intumescent coatings may be designed for protection of metals from fire, such as structural steel. Reviews of the technology are available. [ 3 ] They may be based on a number of resin binders including epoxy , and silicone. [ 4 ]
Intumescent fireproofing is a layer of a material which is applied like paint on the structural steel members. The thickness of this intumescent coating is dependent on the steel section used. Intumescent coatings are applied in a relatively low thickness (usually 350- to 700- micrometer ), have a more aesthetic smooth finish, and help prevent ...
Dormitories in the US are considering or are required by law to use these products. Intumescent coatings are used by various dormitories and in school buildings, especially those with historic structures that lack fire sprinkler systems. [10]
Fire-retardant materials are designed to burn slowly.. Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat.
For example, information on microfilm is destroyed at 65.5 °C (149.9 °F) (a.k.a. Class 150) [citation needed] and magnetic media (such as data tapes) lose data above 51.7 °C (125.1 °F) (a.k.a. Class 125). [citation needed] Fireproof vaults built to meet the more stringent Class 125 requirement are called data-rated vaults. [citation needed]
Flame retardants are a diverse group of chemicals that are added to manufactured materials, such as plastics and textiles, and surface finishes and coatings. [1] Flame retardants are activated by the presence of an ignition source and prevent or slow the further development of flames by a variety of different physical and chemical mechanisms.
Recent research focuses on application of different types of fire retardants during the manufacturing process as well as applications of fire retardants (especially intumescent coatings) at the finishing stage. [20]
This is the rating required to protect microfilm, microfiche, and other film-based information storage media. Above 150 °F (65.5 °C) film is distorted by the heat and information is lost. A Class 150-2 Hour vault must keep the temperature below 150 °F. for at least two hours, with temperatures up to 2,000 °F. (1,093.3 °C) outside the vault.
