FAQS

Leveraging our in-house CNAS‑accredited laboratory, we can tailor the filler-to-resin ratio to meet the demands of challenging operating conditions, such as exposure to strong acids and bases, alternating high and low temperatures, and seawater erosion. Our R&D team is equipped to develop custom‑designed products on demand, providing end‑to‑end support throughout the entire process—from sample testing and pilot‑scale trials to full‑scale production.

Solvent-free coatings can be applied in a single thick coat, reducing the number of coating passes from three to one or two, shortening the construction schedule by 32% and eliminating the risk of ignition in confined spaces. The resulting paint film is dense and free of pinholes, extending the anti-corrosion service life of storage tanks to 20 years and significantly reducing the frequency of future maintenance and recoating.

Yunhu T‑1 modified high‑temperature‑resistant coating offers long‑term service at 200°C and withstands erosion by condensate acid at a 40% concentration, making it suitable for hazardous waste incineration and boiler flue gas applications. It has been successfully deployed in multiple power plant projects; after eight years of operation, the substrate remains free from corrosion, and each boiler has saved approximately RMB 700,000 in equipment replacement costs.

Under normal installation conditions, we offer a 5–10 year warranty and 24/7 technical support. For quality issues, we provide remote assistance within 24 hours and dispatch technicians to resolve the problem on-site within 48 hours. If the issue stems from the substrate, we will provide a free remediation plan to help reduce your future maintenance costs.

Step 1: On-site condition assessment—development of an anti-corrosion plan—sample shipment—performance testing—contract signing. Step 2: Production scheduling and manufacturing, followed by dedicated hazardous‑material delivery. Step 3: Construction‑site technical guidance. Finally, regular follow-up inspections during the warranty period. Throughout the process, a dedicated project manager provides one‑on‑one oversight, ensuring transparency and efficiency.

Our high-solids, solvent-free, water-based product line is manufactured in strict compliance with national standards, with all VOC levels meeting regulatory requirements and supported by third-party test reports. Produced to national green‑factory standards and rigorously validated across numerous Sinopec projects, our products pass environmental inspections on the first attempt, helping you avoid costly production shutdowns and penalties.

Epoxy coatings are suitable for sewage ponds, storage tanks, and underground equipment; polyurethane is ideal for outdoor steel structures; high‑temperature‑resistant coatings are used in flue gas dust collectors; and solvent‑free formulations are best suited for enclosed storage tanks and confined spaces. We will develop a customized coating system tailored to your specific media, operating temperatures, and substrate materials, helping you avoid selection errors.

With over 40 years of expertise in corrosion protection, we hold 26 invention patents and collaborate with universities on industry‑university‑research initiatives, independently developing our own proprietary formulation systems. Our products’ salt‑spray, acid‑alkali, and temperature resistance have been verified through both in‑house CNAS‑accredited testing and third‑party assessments. Under equivalent protection conditions, our total procurement costs are 28% lower than those of imported brands.

We offer end-to-end lifecycle services, including operational condition surveys, formulation selection, material supply, on-site technical briefings, anti-corrosion construction, and post‑installation maintenance. Leveraging an 80,000‑ton intelligent production base, we can both deliver materials and dispatch engineers to the site for comprehensive, on‑site guidance throughout the entire construction process.

We are a high-tech enterprise and a national-level green factory, holding Grade‑I qualifications for waterproofing, anti-corrosion, and thermal insulation construction, CCS ship classification society certification, and ISO’s three major management system certifications. We also operate our own CNAS‑accredited laboratory. We have been consistently shortlisted on the framework procurement lists of Sinopec and PetroChina, with complete sets of test reports that fully meet the tender requirements of central state‑owned enterprises.
