Intumescent paints protect a concrete, steel or timber structure against fire by reacting under the influence of the heat of the fire, forming an insulating layer of foam. Intumescent paints offer the aesthetical advantage of showing the shape of the structure and are extremely light. For timber structures, transparent intumescent paint offers fire protection while preserving the architectural value.
Promat offers different intumescent paints to suit the type of structure to be protected, the required fire resistance rating and durability requirements, even for external application.
Promat spray coatings are used to protect steel, concrete or wood structures against fire.
Reacting at temperatures from 270 ° C to 300 ° C, intumescent paints and varnishes expand about 20 times their thickness under the effect of heat.
In order to ensure the performance of its systems, Promat offers a wide range of glue and coating which, combined with the range of Promat sheets, guarantee the fire resistance and durability performance of the systems.
Promat offers a wide range of products (bags, pastes, sealants and liquid coatings, necklaces, bricks, stoppers, sheaths, intumescent strips, etc.) which, thanks to their intumescent power, ensure fire performance on the surface of the hoppers ( expansion in contact with heat from 150 ° C).
