Comprehensive Introduction to Cementitious Fireproofing and Epoxy Intumescent Fireproofing

Cementitious Fireproofing is a traditional and classic thick-coat passive fire protection material, mainly composed of inorganic cement, lightweight thermal insulation fillers and other components. It achieves thermal insulation and fire protection through its extremely low thermal conductivity, does not expand or shrink when exposed to fire, and blocks heat transfer through a stable porous structure to prevent steel from losing strength at high temperatures. This system complies with mainstream standards such as UL 263, ASTM E119 and GB 14907, and is a commonly used fire protection system for onshore industrial projects
.
Epoxy Intumescent Fireproofing is the mainstream thin-coat solution for international high-end projects, marine engineering and modular construction. It adopts a two-component epoxy formula, integrating fire protection and anti-corrosion functions. When exposed to fire, it can quickly expand to form a dense carbonized thermal insulation layer, which can cope with hydrocarbon fires and jet fires, meeting high-level requirements such as UL 1709. Due to its characteristics of light weight and high durability, it has become the first choice for offshore wind power, FPSO, export modules and other projects
.
Cementitious Fireproofing is mainly applied to onshore heavy steel structures and large-scale industrial facilities, including petrochemical plants, oil refineries, LNG receiving terminals, pipe rack supports, industrial workshops, etc. It has controllable cost and flexible construction, can be prefabricated and sprayed in workshops or constructed on-site, and is suitable for large-area conventional fire protection areas that are cost-sensitive and have low appearance requirements.
Epoxy Intumescent Fireproofing is more suitable for high-standard and high-corrosion environments. Its core application scenarios include offshore wind power modules, FPSO offshore production facilities, overseas export steel structure modules, marine platforms, etc. It is resistant to salt spray, impact and chemical corrosion, can be matched with heavy anti-corrosion systems, adapts to harsh environments such as marine transportation and marine atmosphere, and meets the requirements of lightweight and aesthetics
.

The advantages of Cementitious Fireproofing are low cost, stable fire resistance, good weather resistance, high construction fault tolerance, and suitability for large-area construction; its disadvantages are thick coating, high self-weight, which increases structural load, rough appearance, and is not suitable for lightweight scenarios and those with high aesthetic requirements
.
The advantages of Epoxy Intumescent Fireproofing are thin coating, light self-weight, integrated fire and corrosion protection, beautiful surface, and adaptability to automatic workshop spraying; its disadvantages are relatively high material and construction costs, and stricter requirements on construction environment and equipment
