Passive materials for fire safety separate steel structures from the effects of the high temperatures that may be produced in fire. They can be divided into two categories, non-reactive, of which the most common examples are boards and sprays, and reactive, of which the most common example is thin film Intumescent Paint NSW. Thin intumescent film coatings may be applied either on-site or off-site.
Intumescent Coatings
Intumescent Paint NSW are paints and materials that are inert at low temperatures but are usually sealed at temperatures between 200 and 250 ° C due to complex chemical reactions. The steel products will not be impacted at these temperatures. They swell as a result of this reaction and have an extended layer of char with low conductivity.
Two large families can be classified into intumescent coatings: thin film and thick film. Thin film materials are either solvent-based or water-based, and are used mainly for fire construction. Initially, thick film Intumescent Paint NSW were developed for the offshore and hydrocarbon industries but were adapted for use in buildings.
These are primarily used in buildings needing 30, 60 and 90 minutes of fire-resistance. A variety of items have been produced in recent years that can provide fire resistance of 120 minutes. They can be installed on the spot or off-site. Most on-site applications are generally done using water-based materials. But when there is no end use in a dry, heated environment for the structure to which the material is applied then solvent-based materials are generally used. Solvent-based materials often tend to cover a broader variety of section factors than water-based materials and can be used on-site to secure smaller, high-thickness parts.
