A Vermiculite Spray NSW maybe used for protecting a structure from fire. Also an intumescent paint as a passive protection against fire which reacts chemically while heating the fire. The coating then expands for forming char, which in turn helps in protecting the steel work only for a specific period from heat of fire.
Why and when do you need intumescent coating?
The main aim of passive fire protecting techniques is to help the occupants of the building leave it as soon as possible. Steel is considered to be extremely strong as well as a versatile material for building. But at a temperature of about 550 degrees it starts losing the structural integrity.
Intumescent paint for protection of steel is usually very thick as well as opaque. It is finished with very thin layer of protective fire retarding coating just like gloss. The intumescent coats are usually applied through an airless spray for giving a smooth finish. This remains stable at an ambient temperature. The composition of the coating is based mainly on organic resin binder which is epoxy or rubber.
Once dried, the passive fire stopping intumescent coats is the reactive layer. Thus it becomes quite important to get the right thickness of dry film for getting the requisite fire resistance. The thickness of the film is measured through a wet gauge of film. Some of the coats of paint could be applied for building up for totally dry coating the thickness and for providing the mush required protection from heat.
