Seaton SEAPUR Water-Based Self-Matting Polyurethane Leads New Standards for Green Coatings

In 2025, with the EU REACH regulation continuously expanding its SVHC (Substances of Very High Concern) list, China's "Dual Carbon" strategy advancing deeply, and local governments imposing stricter total VOC emission controls, the green transformation of the coatings industry has shifted from an "optional" to a "must-have." In this context, how to find water-based resin raw materials that meet stringent environmental regulations without sacrificing coating performance has become a question every responsible coatings company must answer.

Guangdong Seaton Advanced Materials (SEATON)'s SEAPUR series of water-based self-matting polyurethane dispersions provides the answer through a unified commitment across seven products: the entire line is APEO-free and free from formaldehyde and formaldehyde-releasing substances, achieving high-performance coating results on the foundation of green compliance.

I. APEO: The "Hidden Risk" the Coatings Industry Must Address

APEO (Alkylphenol Ethoxylates) is a class of chemicals formerly widely used as surfactants. In the synthesis of polyurethane dispersions, acrylic emulsions, and other water-based resins, some products use APEO-type emulsifiers to stabilize dispersion systems. However, upon environmental degradation, APEO produces alkylphenols with endocrine-disrupting activity (such as nonylphenol NP and octylphenol OP), which can mimic estrogen and disrupt biological endocrine systems. APEO has been listed on multiple international green standards' banned or restricted substance lists, including the EU REACH Regulation (Annex XVII, Entry 46), Oeko-Tex Standard 100, and SG certification.

Key Compliance Milestone: Since 2021, the EU has formally and completely banned textiles and leather products containing APEO from entering the EU market (REACH Annex XVII, Entry 46). The China Coatings Industry Association has also encouraged the industry to advance APEO substitution.

The TDS (Technical Data Sheets) for all SEAPUR series products explicitly state: "This product contains no intentionally added alkylphenol ethoxylates (APEO)." This commitment means that at the product design stage, Seaton incorporated APEO-alternative emulsifier systems into its formulation development standards, eliminating compliance risks for end customers at the source — whether exporting to the EU or meeting green certification requirements.

II. Formaldehyde: The Core Sensitive Indicator for Home and Consumer Goods Industries

Formaldehyde and formaldehyde-releasing substances are among the most closely watched harmful substance indicators by consumers in furniture coatings, wood paints, textile coatings, and other market segments. China's national standards GB 18583 and GB 18584, EU wood coating formaldehyde emission limits, and OEKO-TEX textile certifications all specify clear formaldehyde limits.

The TDS for the SEAPUR series (50G71, 50G72, 50G75, 50G80, 50G85, 50G89, 50G91) explicitly declares: "Free from formaldehyde and formaldehyde-releasing substances." This has direct value for downstream coating formulators and end-brand manufacturers — water-based formulation systems built with SEAPUR resins possess inherent compliance advantages on formaldehyde metrics, significantly simplifying product certification processes and reducing testing risks.

III. Water-Based Transformation: From VOC Reduction to Full-Chain Greening

Compared to solvent-based polyurethanes, the SEAPUR series — as water-based dispersions — offers systematic environmental advantages:

Notably, SEAPUR 50G80 goes further by achieving "filler-free" self-matting — no matting powders such as silica are added, reducing the additional environmental burden caused by solid fillers in formulations. It is one of the self-matting resins closest to the "clean formulation" concept.

IV. Product Certifications and Downstream Compliance Applicability

Based on the technical characteristics of the SEAPUR series, its compliance applicability is particularly outstanding in the following application scenarios:

• EU export leather/textiles: APEO-free commitment directly corresponds to REACH Annex XVII Entry 46 compliance requirements

• Children's furniture/toys: Formaldehyde-free commitment meets EN 71, GB/T 22788 and other children's product formaldehyde limit requirements

• Green building material certification: Low-VOC water-based formulations facilitate overall coating products obtaining China's green building material product certification (Ten-Ring certification, etc.)

• OEKO-TEX certified textiles: APEO-free and formaldehyde-free meet the core harmful substance requirements of Oeko-Tex Standard 100

• Automotive interior VOC standards: Water-based formulations meet interior part VOC emission limits of major OEMs (VW, BMW, Toyota, etc.)

V. Green Procurement Trends Under the Dual-Carbon Goal

Under the national strategy framework of "Carbon Peak and Carbon Neutrality," manufacturing enterprises face increasing pressure for green supply chain management. An increasing number of brand owners and OEM manufacturers require suppliers to provide environmental declarations, VOC content certifications, and even carbon footprint data for raw materials. Choosing the SEAPUR series water-based self-matting polyurethane is not only a coating technology choice but also a supply chain green compliance investment:

• Helps downstream coatings companies respond to customer green audits and improve supplier ratings

• Reduces risks of product recalls and trade barriers caused by harmful substance exceedances

• Provides traceable green raw material usage data to support brand owners' ESG reporting

• Aligns with increasingly stringent domestic and international chemical management regulations, reducing long-term compliance costs

VI. Guangdong Seaton Advanced Materials: A Long-Term Commitment to Green R&D

Since its establishment, Guangdong Seaton Advanced Materials Technology Co., Ltd. has consistently regarded "green, high-performance, and precision application" as its core R&D direction. The green design philosophy of SEAPUR series products runs throughout the entire development process:

• Selection of APEO-alternative emulsifier systems, eliminating harmful emulsifiers at the molecular design level

• No use of formaldehyde or formaldehyde-releasing crosslinking aids; the formulation system is inherently formaldehyde-free

• Continuous optimization of water-based dispersion processes to reduce VOC co-solvent usage while improving solids content and storage stability

• Providing customers with complete Technical Data Sheets (TDS) and environmental declaration documents to support their downstream compliance management

Seaton understands that green is not a slogan — it is a systematic engineering effort behind every formulation choice and every testing verification. The SEAPUR series is Seaton's concrete manifestation of its green commitment in the field of water-based self-matting polyurethane.

VII. SEAPUR Series Green Attributes Overview

Conclusion: Choosing Green Raw Materials Is Choosing the Future

Facing increasingly stringent domestic and international environmental regulations, and facing brand owners' urgent demand for green supply chains, choosing the water-based, APEO-free, formaldehyde-free SEAPUR series self-matting polyurethane is not only a technical optimization but also a proactive layout for enterprises on the path of green development. Seaton Advanced Materials is willing to work hand in hand with coatings companies and manufacturers worldwide to jointly advance the green transformation of China's coatings industry — making high performance and environmental compliance no longer a dilemma, but complementary product competitiveness.
