1. Introduction

China GB 38508 has tightened VOC limits for interior coatings, driving waterborne colorant demand. This paper analyzes 3 sustainability directions based on DENSON WT series market data.

2. Market Drivers

Low-VOC regulation, green building policies and customer ESG requirements are pushing solvent-based systems to waterborne. Total cost of ownership is typically 10-15% lower for waterborne solutions.

3. Direction 1: Low-VOC Architectural Coatings

Architectural waterborne colorants require VOC≤80 g/L (GB 38508) and washability≥3500 cycles (GB/T 9266).

4. Direction 2: Anti-corrosion for Industrial Maintenance

Fig.2 Stainless steel reactor production

Waterborne epoxy and polyurethane systems achieve salt spray≥720 h (GB/T 1771), suitable for infrastructure.

5. Direction 3: Wood and Furniture

7. Conclusion

Waterborne colorants will continue to grow under low-VOC and ESG drivers; DENSON WT series supports stable, cost-effective switching.

8. FAQ

Q1: Is waterborne colorant always more expensive?
A: Raw material may be higher, but lower VOC treatment and compliance cost offset it; total cost is 10-15% lower.

Q2: What is the main regulatory driver?
A: GB 38508 limits VOC in interior coatings and accelerates replacement of solvent-based systems.

Q3: Can existing lines switch to waterborne?
A: Yes, but stainless steel equipment and pH 8-9 control are required to avoid corrosion.

Q4: What performance should be verified?
A: Washability (GB/T 9266), salt spray (GB/T 1771) and D50 (GB/T 19077).
