Shanghai Handai Chemical Unveils Its 21st Innovative Product of 2026: HYH6721 Cycloaliphatic Amine Curing Agent

Shanghai Handai Chemical proudly introduces the 21st innovation in its 2026 series — the HYH6721 Cycloaliphatic Amine Curing Agent.

HYH6721 is a clear, transparent liquid with a viscosity of 1500–4000 cps at 25°C and an amine hydrogen equivalent of 91. These stable and reliable technical parameters ensure precise performance for a wide range of applications.

The product is highly versatile and particularly suitable for industrial coatings, marine and offshore maintenance coatings, civil engineering and concrete repair materials, as well as fast-curing structural adhesives. Whether in large-scale outdoor projects or precision industrial coating applications, HYH6721 delivers outstanding performance.

As a medium-viscosity epoxy curing agent specifically designed for low-temperature environments, HYH6721 adapts perfectly to demanding application conditions and offers multiple key advantages: rapid curing at low temperatures, significantly shortening construction cycles and improving project efficiency; excellent moisture resistance and anti-blooming properties, ensuring clear and durable coatings even in high-humidity conditions; outstanding color stability that effectively prevents yellowing for long-lasting aesthetics; exceptional chemical corrosion resistance, providing durable substrate protection; and low odor, creating a healthier and more comfortable working environment for operators. These combined strengths support efficient construction and long-term protection, offering reliable assurance for various engineering projects.

Handai Chemical remains committed to its brand philosophy of 'Innovating for a better life,' striving to create greater value for customers through technological innovation.
