What are the application ranges of fire-retardant coatings?

The steel structure substrate is the primary application area for fire-retardant coatings, with the aim of enhancing the fire resistance limit of steel structures (which tend to soften and collapse at high temperatures).

Chaohui Chemical Suzhou Team Building Event

The autumn charm permeates the city of Gusu, as we unite our hearts and pool our strength to embark on a new journey. Temporarily stepping away from our busy work, we’ll unwind amidst mountains and waters, strengthen our bonds through collaboration, and together write a new chapter of unity and progress for Chaohui Chemical.

What is the fire-retardant principle of fire-retardant coatings?

The fire-retardant principle of fire-retardant coatings essentially lies in the physical and chemical changes that occur within the coating itself, creating a protective system that provides thermal insulation, flame retardancy, and smoke suppression under high-temperature fire conditions. This system slows down the temperature rise of the substrate, inhibits the spread of fire, and extends the fire-resistance duration of the substrate.

This coating is easy to apply, dries quickly, is non-toxic, and safe to use. This product can be applied to surfaces made of cement mortar, concrete, cement-asbestos boards, ceilings, and other substrates.

Crossing mountains and seas, let’s talk about cooperation! A delegation of Russian clients visited our company for an inspection and study tour.

On November 14, 2025, a delegation of Russian clients traveled from afar to visit our company, conducting on-site inspections and engaging in in-depth exchanges, with a particular focus on the core business of paint production. The company’s management team provided full-time accompaniment and hospitality throughout the visit. Both sides held highly efficient discussions on topics including paint business cooperation, production processes, and market applications. The entire exchange session was smoothly coordinated, practical, and substantive, resulting in the reaching of multiple areas of consensus.

Coating Defect Detection

In the protection of large-scale structures such as bridges, storage tanks, and pipelines, coating systems act like a “shield”—a protective armor that effectively blocks external corrosion and significantly extends the service life of these structures. However, if this “armor” contains discontinuities—such as pinholes or missed coatings—it can become a hidden “entry point” for structural degradation. Oxygen and electrolytes from the outside environment can seep through these gaps into the substrate, causing corrosion of the metal base material and seriously compromising the structure’s safety and durability. Today, we’ll talk about how to identify these hidden coating defects through scientific testing.

How much do you know about fire-retardant coatings for steel structures?

Anti-corrosion systems: ISO 12944 standard ranges from C1 to C5.

Corrosion is the phenomenon in which materials—primarily metals—undergo chemical or electrochemical reactions with their surrounding environment, leading to a deterioration of their performance. In the fields of construction, industry, and marine engineering, corrosion prevention has always been a critically important issue. Whether it’s towering steel structures reaching into the clouds or offshore facilities deep beneath the sea, corrosion can become a source of safety hazards. The international standard ISO 12944 is the most widely used standard for specifying corrosion protection levels and is extensively applied in the protective design of steel structures, industrial equipment enclosures, and outdoor equipment.

Waterproofing Solution for the Bottom Edge Plate of Steel Storage Tanks

Currently, the conventional practice for waterproofing tank bottom plates in China involves sealing joints with asphalt or applying asphalt-sand coatings. Some also use rubber-modified asphalt or epoxy glass cloth for waterproofing. However, the former suffers from poor aging resistance and insufficient bonding strength, while the latter exhibits poor elasticity, leading to cracking and delamination after use—both resulting in less-than-ideal performance. Additionally, there has been an attempt to employ ternary ethylene-propylene-diene monomer (EPDM) rubber sheets for corrosion protection; yet, their surface tends to crack easily, thereby losing their waterproof and anticorrosive effectiveness. In response to these issues, our company has conducted on-site investigations and research, and has developed a highly effective and comprehensive waterproofing and anticorrosion solution. Specifically, building upon our CTPU elastic polyurethane waterproofing coating, we have adjusted the formulation by adding a certain amount of filler to create granular compounds and paste-like materials. We then employ a construction technique that involves laminating polyester waterproof mesh fabric to enhance the coating’s strength, thereby effectively blocking the pathways through which corrosive agents such as rainwater and dew can penetrate the edge plates and tank bottom plates, thus achieving the goal of protecting the tank bottom plates.
