Description
Long Life Ultra-Thin Steel Structure Fireproof Coating
The ultra-thin steel structure fireproof coating produced by our company has the following characteristics:
1. Excellent fire performance: the coating can expand rapidly when heated by fire, forming a solid refractory heat insulation barrier, with thin coating, high foaming rate, the formation of heat insulation bubble layer uniform and dense characteristics. Less than a millimeter of coating can expand into nearly 20 millimeters of foam insulation, and the uniform dense carbon layer increases the fire resistance of the steel structure.
2. Excellent environmental performance: the coating has the characteristics of high solid content and low VOC content, solid content up to 75%, small volatile amount of organic matter, environmental protection and safety, suitable for use in closed environments such as building rooms and ship cabins. The paint with water as the solvent, less volatile organic matter, low environmental pollution, to overcome the oil-based fireproof paint flammable and explosive, toxicity, transportation, storage and use of unsafe shortcomings, is conducive to environmental protection and production, construction personnel health and safety.
3. Excellent coating performance: The coating has the advantages of easy coating and strong adhesion while having high solid content.
4. Ultra-thin coating; reducing the load weight under the premise of ensuring the fire protection effect is of great significance in the field of aviation and aerospace, as well as in the use of ships and key parts.
are specialized intumescent paint-like materials applied to the surface of steel structural members to provide fire resistance. These coatings expand and char when exposed to high temperatures, creating an insulating layer that protects the underlying steel from rapid heating and loss of structural integrity during a fire.Ultra-thin steel structure fireproof coatings
