Abstract
A method of providing fire protection to a structure includes the step of installing an intumescent mesh on a surface of the structure such that the intumescent mesh is exposed to outdoor environmental conditions. The intumescent mesh includes a mesh with a series of openings and an intumescent coating applied to the flexible grid such that air can pass through the openings in the intumescent mesh. The intumescent coating includes expandable graphite and a polymer-based carrier; and the intumescent coating does not degrade when exposed the outdoor environmental conditions. The intumescent coating remains flexible and resists cracking and spalling from the flexible grid.
Claims8
A method of providing fire protection to a structure, the method comprising the steps of:
- installing an intumescent mesh on a surface of the structure such that the intumescent mesh is exposed to outdoor environmental conditions, the intumescent mesh comprising a flexible grid coated with an intumescent coating such that the intumescent mesh defines a series of openings, the flexible grid being coated such that air can pass through the series of openings in the intumescent mesh, and the outdoor environmental conditions comprising at least precipitation and direct sunlight;
- wherein:
- the intumescent coating comprises expandable graphite and a polymer-based carrier;
- and
- the intumescent coating does not degrade when exposed the outdoor environmental conditions such that the intumescent coating remains flexible and resists cracking and spalling from the flexible grid.
