Intumescent paints are primarily designed for the protection of structural steel from fire. The products works by expanding when heated to form an insulating char around the substrate being protected. In ambient conditions the thin coating allows for the steel structures to maintain their usual form rather than being boxed in with a board or covered with fire spray.
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).
