DINGPRECISION Dual Spray, Dual Coat, Dual Compliance Coating Solution:

Mastering 2026 New National Standards & EU REACH in One Go

Introduction: Dual Compliance is Rapidly Becoming a Prerequisite, Not a Bonus

On August 1, 2026, six new national safety standards for coating, including GB 14444-2025 "Safety Technical Requirements for Spray Booths", will be officially implemented. Simultaneously, the EU (EU) 2024/3190 Bisphenol A ban will take full effect in 2026.

For manufacturing enterprises in the Guangdong-Hong Kong-Macao Greater Bay Area, products must now comply with both new domestic standards and EU export regulations. Dual compliance is rapidly transforming from a competitive advantage into a mandatory requirement.

We are DINGPRECISION (Foshan Dingyi Industrial Technology Co., Ltd.), located in Beijiao, Shunde, specializing in precision sheet metal fabrication and coating processing. This article, centered on our "Dual Spray, Dual Coat" process, systematically deconstructs the dual challenges of the 2026 New National Standards and EU regulations, and explains how we can meet both sets of requirements with a single system.

1. Why is the Greater Bay Area Facing Dual Compliance Pressure First?

The Guangdong-Hong Kong-Macao Greater Bay Area is one of the regions with the highest density of manufacturing exports in China. Taking Foshan Shunde as an example, it hosts significant clusters of the home appliance, energy storage, robotics, liquid cooling, and medical device industries, with products exported extensively to Europe, North America, and Southeast Asia.

The EU REACH regulation Annex XVII is tightening restrictions on substances in coatings annually. (EU) 2024/3190 directly prohibits the use of Bisphenol A (BPA) in food contact coatings, with a detection limit as low as 1 μg/kg.

The pain points for Greater Bay Area enterprises are very concentrated:

Non-compliant coating = Full batch rejection + Customer compensation claims + Supplier downgrade

For sheet metal OEM and coating enterprises, this means: Those who establish dual compliance capabilities first secure the ticket to export orders; those still using outdated processes will be eliminated from the supply chain.

2. Core Changes in the 2026 New National Standards: Six Coating Safety Standards Updated Simultaneously

From August 1, 2026, six new national safety standards for coating will be implemented simultaneously, covering the entire chain of spray booths, drying ovens, electrostatic spraying, exhaust gas purification, safety management, and electrostatic spray guns:

表格

Direct impact on coating enterprises:

• Spray booths must refine hazardous area classification per GB 14444-2025, upgrade ventilation, and interlock systems.

• Drying ovens require temperature control and combustible gas monitoring to eliminate safety hazards during the baking process.

• Electrostatic spraying requires implementing static grounding and workpiece resistance requirements to ensure operational safety.

• Organic waste gas purification devices must meet VOC purification efficiency and explosion-proof requirements, integrating environmental protection and safety.

3. Tightening EU Regulations: REACH & Bisphenol A Ban

3.1 EU REACH Regulation Continues to Tighten

EU REACH Annex XVII is tightening restrictions on substances in coatings annually, involving heavy metals, phthalates, bisphenols, etc. Coating products exported to the EU must provide compliance declarations and test reports.

3.2 (EU) 2024/3190 Bisphenol A Ban

(EU) 2024/3190 directly prohibits the use of Bisphenol A (BPA) in food contact coatings, with a detection limit as low as 1 μg/kg. This means:

• Coatings for food contact products (e.g., air fryer inner linings, food containers) must be BPA-free.

• The extremely low detection limit imposes higher requirements on the entire chain: coating raw materials, pretreatment, and application.

• The supply chain must be traceable, with full documentation from raw materials to final product testing.

3.3 Essence of Dual Compliance: One System, Two Sets of Standards

Dual compliance is not about maintaining two separate systems – "one for domestic, one for EU." It is a single, fully traceable compliance system spanning from raw materials to finished product testing, meeting both national standards and EU requirements simultaneously. This is the core value of the DINGPRECISION Dual Spray, Dual Coat process.

4. Detailed Explanation of the Dual Spray, Dual Coat Process: DINGPRECISION's Core Coating Capability

4.1 What is Dual Spray, Dual Coat?

Dual Spray, Dual Coat is DINGPRECISION's core coating process system. It refers to a complete two-layer coating scheme involving two spray applications (primer + topcoat) and two baking cycles:

Pretreatment (Zirconization) → Primer Spray (20-30 μm) → Flash-off (5-15 min)
→ Topcoat Spray (Total thickness 40-60 μm) → Baking (120-180°C × 20-40 min) → Final Inspection
