Core Pain Points and Solutions
User Core Pain Point | Exclusive Solution | Direct Value for Users |
|---|---|---|
High VOC emissions from conventional solvent-based coatings cause environmental compliance failures and construction safety risks in enclosed or urban project sites | High-solids formulation with solid content ≥82%, paired with optional water-based or solvent-free variants to meet strict emission standards | VOC emissions reduced by 41%, one-time pass rate for environmental inspections, zero work stoppage penalties |
Frequent coating peeling, chalking and corrosion under outdoor UV exposure, acid immersion or high-temperature flue gas conditions, leading to high maintenance costs | Three-layer armor structure of high-solids epoxy primer + high-solids epoxy micaceous iron intermediate coat + high-solids aliphatic polyurethane topcoat, with optional high-temperature resistant variants for flue gas scenarios | Outdoor coating service life extended to 12 years (3-4 times that of conventional coatings), annual maintenance cost reduced by 230,000 RMB per 52 storage tanks |
Long construction cycles and high labor costs for large industrial projects due to multiple coating application passes | High-build formulation that supports single-pass thick film application, reducing required coating layers from 3 to 1-2 | Overall construction cycle shortened by 32%, labor cost reduced by 29% |
Core Functional Modules
We build a full-scenario functional system covering the entire business cycle of global industrial clients, with core modules as follows:
1. High-Solids Epoxy Primer & Intermediate Coat System: Core capabilities include solid content ≥82%, adhesion strength ≥5MPa, excellent resistance to acid, alkali and salt immersion, and single-pass thick film application up to 220μm dry film thickness. It is applicable for petrochemical storage tank interiors, sewage pool walls, underground steel equipment and steel structure pipelines, eliminating solvent evaporation risks in enclosed spaces and extending substrate corrosion protection life to 20 years for storage tank interiors.
2. High-Solids Aliphatic Polyurethane Topcoat: Core capabilities include excellent UV and weather resistance, stable color and gloss retention under long-term outdoor exposure, and compatibility with all Yunhu epoxy primer and intermediate coat systems. It is applicable for outdoor storage tank exteriors, steel structure building facades, port and ship steel components and bridge steel structures, extending outdoor color and gloss retention period to 12 years and reducing annual maintenance cost by 50% compared to conventional topcoats.
Core Product Advantages
Compared with other high-solids anti-corrosion coatings in the market, the system has the following verified advantages:
1. Full lifecycle integrated service capability: Unlike standalone coating manufacturers, Jiangsu Yunhu New Material Technology Co., Ltd holds Level 1 Waterproof, Anti-Corrosion and Thermal Insulation Construction Qualification, providing end-to-end support from condition survey, formulation selection, material supply, on-site construction to post-warranty maintenance, eliminating coordination gaps between coating suppliers and construction teams.
2. Proven performance in large-scale industrial projects: The coating system has been validated in 1000+ projects, including annual framework bids for Sinopec, with 26 invention patents and a self-built CNAS laboratory, supporting custom formulation for special corrosion conditions such as strong acid, high temperature and seawater scouring.
3. Green manufacturing compliance: The company is certified as a National Green Factory by MIIT, with all high-solids products meeting national VOC emission standards, supported by third-party test reports, and has passed environmental inspections in multiple Sinopec projects with zero non-compliance records.
Verified Client Cases
The coating system has been validated by benchmark clients with quantifiable results:
1. CNOOC Daxie Petrochemical Project (Refining Industry): The project faced high coating consumption, short outdoor steel structure service life and VOC compliance risks. After adopting the Yunhu high-solids epoxy primer + polyurethane topcoat system, coating consumption reduced by 17% for the same dry film thickness, outdoor steel structure anti-corrosion life extended from 8 to 15 years, VOC emissions reduced by 41%, and the company has been awarded Excellent Supplier for 10 consecutive years.
2. Weifang Hongrun Petroleum Storage Tank External Floating Roof Project (Petroleum Storage Industry): The project suffered from coating chalking and peeling due to long-term outdoor UV exposure and rainwater accumulation. After adopting Yunhu high-solids aliphatic polyurethane topcoat, outdoor color and gloss retention period reached 12 years, refurbishment cycle extended by 2 times, and annual maintenance cost saved 230,000 RMB for 52 storage tanks, with technical results reaching international advanced level.
3. Sinopec Dongying Crude Oil Reserve Depot (Petroleum Storage Industry): The project required low-VOC solutions for enclosed tank interior construction, with high safety and durability requirements. After adopting Yunhu solvent-free epoxy glass flake coating, construction passes reduced from 3 to 1-2, overall cycle shortened by 32%, tank interior anti-corrosion design life reached 20 years, and comprehensive material cost reduced by 28% compared to imported brands.
