A Smarter Choice for the Next Generation of Industrial Anti-Corrosion Coatings
With the official implementation of GB 30981.2-2025, the new national standard for harmful substance limits in industrial coatings, industrial anti-corrosion coatings industry has entered a new era of stricter green compliance.
The new regulation tightens control over VOCs, free isocyanates, PFAS (per- and polyfluoroalkyl substances) and other hazardous substances, exposing the environmental limitations of traditional PU and fluorocarbon coatings.
Focusing on modified polysiloxane technology, Quark New Material has independently developed Durle® Epoxy Modified Polysiloxane Resin, offering a high-solid, low-VOCs, safe, and low-carbon solution for the green transformation of industrial anti-corrosion coatings.
Three Core Advantages for Precise Compliance with the New Standards
1. Regulatory Compliance with Significantly Lower VOCs
Durle® Epoxy Polysiloxane Resin SH-2110E features high solids and low viscosity, with a resin solid content of up to 97% ±2%, making it ideal for high-solid and solvent-free formulations.
The VOC content of finished coatings is lower than 100 g/L, offering a significant advantage compared to conventional: PU coatings (>350 g/L) Fluorocarbon coatings (>400 g/L)
Starting from the raw material source, Durle® helps coating manufacturers easily meet the mandatory low-VOCs requirements of GB 30981.2-2025, reducing compliance pressure and supporting sustainable production.
2. Safer Raw Materials for Simplified Storage, Transportation, and Application
Durle® formulations are free of isocyanates and heavy metals, fundamentally eliminating the occupational health risks and application hazards commonly associated with PU and fluorocarbon systems.
In addition, the product is classified as non-hazardous, which means:
No hazardous chemical storage qualification required
Simplified logistics and transportation
Easier on-site coating operations
Lower supply chain management costs
This creates a safer and more efficient full-process solution from warehousing to application.
3. PFAS-Free and Lower Carbon for a Sustainable Future
Durle® Polysiloxane features a Si-O backbone structure with lower carbon content, significantly reducing dependence on petroleum-based raw materials compared with PU and fluorocarbon systems.
Resulted in: Lower carbon emissions Reduced environmental footprint Better alignment with carbon neutrality goals. At the same time, its PFAS-Free formulation eliminates the environmental compliance risks increasingly faced by fluorocarbon coatings under global PFAS restrictions.
This makes Durle® a future-ready solution aligned with dual-carbon strategy and global sustainability trends. At this critical turning point under strict policy, choosing Durle® Polysiloxane Resin enables coating manufacturers to address compliance challenges at the source—whether related to excessive VOCs or restricted hazardous substances.
Beyond compliance, Durle® also delivers long-term anti-corrosion performance, helping customers enhance product competitiveness and seize opportunities in the accelerating green transformation of industrial coatings.
