Focus on CHINACOAT 2026 | A.H.A Presents Full Range of Powder Coating Additives and Curing Agent Solutions in Guangzhou

On November 11, 2026, CHINACOAT 2026 — the 2026 China International Exhibition for Coatings, Inks and Adhesives — together with SFCHINA 2026, the 2026 China International Exhibition for Surface Treatment, Coating and Coating Products, opened at Area A of the China Import and Export Fair Complex in Guangzhou. This edition also marks the 30th anniversary of CHINACOAT.

A.H.A is exhibiting its full portfolio of crosslinking agents, matting agents and functional additives for powder coatings. On the opening day, the booth welcomed numerous customers and industry peers from China and abroad, with in-depth discussions centered on practical application needs such as formulation optimization, low-temperature curing, matte effects, and weatherability and anti-corrosion performance.

01 Full Range of Additives and Curing Agents Covering Mainstream Powder Coating Systems

The products on display are grouped by application into six categories: crosslinking agents, matting solutions, degassing agents, flow modifiers, texture agents and catalysts. They cover TGIC, HAA, PUR and hybrid powder coating systems, providing matched product selections for different end-use applications.

02 HAA Systems: Standard, Yellowing-Resistant and Pinhole-Free Crosslinking Agents Plus Patented Matting Solutions

The HAA section features three crosslinking agents: the standard grade AHA6552 (CAS: 6334-25-4), the yellowing-resistant grade AHA6553 (CAS: 57843-53-5), and the pinhole-free grade AHA6554 (a compounded mixture), matching different weatherability and surface appearance requirements.

The accompanying patented matting agent AHA2138 enables one-step matting in wax-free formulations, achieving gloss levels down to approximately 10%. The gloss-versus-dosage curves in the booth graphics show that, as AHA2138 loading increases from 2% to 10%, the gloss of both white and black coatings steadily decreases to low levels.

03 PUR Systems: Blocked Crosslinking Agents and Dedicated Matting Agents

The PUR section features four blocked PUR crosslinking agents — AHA6630, AHA6640, AHA6650 and AHA6680 — covering blocked IPDI and blocked H12MDI types.

The accompanying matting agent AHA2160 (patent pending) supports one-step matting without the need for high-hydroxyl-value polyester resins and without wax, while reducing the amount of PUR crosslinking agent required. Gloss curves show that, at loadings of 10%–16%, the gloss of both white and black coatings can be reduced to approximately 10 GU or below.

04 Low-Temperature Curing Solutions: Dual Lineup for Matte and Gloss

Responding to the need for energy savings, cost reduction and heat-sensitive substrates, the company is showcasing low-temperature curing solutions. On the matte side, the matting curing agent AHA2203 (patent pending) achieves full cure at temperatures as low as 130°C, with gloss as low as 4 GU under 130°C curing conditions. Based on a special carboxyl-functional design, it offers excellent storage stability.

On the gloss side, the phenol-excess crosslinking agent supports both low-temperature curing and high-temperature rapid curing: full cure at 130°C/30 min, rapid cure at 200°C/2 min, and IR curing at temperatures as low as 120°C/2 min. It delivers excellent leveling, gloss of up to 105 GU, and only slight color change.

05 Functional Solutions: Anti-Cathodic Disbondment and High-Crosslink Heat-Resistant Systems

In the functional powder coatings section, the AHA3370 anti-cathodic disbondment additive, at a loading of 0.5%, raises conversion efficiency from 88.3% to 96.3% and reduces the cathodic disbondment value from 8.0 mm to 4.8 mm, significantly improving CD test performance.

AHA EP400 is designed for high-crosslink, heat-resistant systems, suitable for high-performance coatings and FBE powder coatings with higher Tg. It withstands harsh thermal conditions and offers excellent chemical resistance and corrosion resistance. In a reference formulation: 60° gloss 97, impact test passed (200 kg·cm), gel time at 200°C 30 s, Tg 146.9°C.

06 CNAS-Accredited Laboratory Backs Product Consistency with Quality Assurance

The company operates a laboratory accredited by the China National Accreditation Service for Conformity Assessment (CNAS) in accordance with ISO/IEC 17025:2017 (the quality inspection center of Anhui Jinlang New Material Technology Co., Ltd., under AHA International, with ilac-MRA mutual recognition). It can conduct high-level coating performance testing and issue professional test reports bearing the CNAS mark, serving as important support for ensuring consistent customer product quality.

A.H.A has 45 years of professional foreign trade experience and resources, and is a comprehensive enterprise group integrating distinctive international trade with high-end pharmaceutical R&D and manufacturing, committed to providing global customers with one-stop professional international trade solutions. The company has obtained AEO Advanced Certification, ISO, BRC, EcoVadis (2023 Gold) and ESGG certifications, among others. CHINACOAT 2026 runs from November 11 to 13. Customers and industry peers are warmly welcome to visit the A.H.A booth at 4.1C49 to exchange ideas, request samples and discuss cooperation.
