The intumescent paint function is to retard the destructive action in a fire. Reacts under the action of heat to form a carbonized foam that protects the metal structure, thus retarding the time and prevents exceeding 500 ° C.

So that its efficiency is maximized, as to retard the spread of fire time, consider the film thickness (this will depend on each surface), and application.The correct calculation of the necessary thickness will depend on the massiveness of the profile , fire and stability necessary to consult the manufacturer tests. From 15 to 120 minutes.
