Shanghai Handai Chemical Grandly Launches Its 25th Innovative Product of 2026: HYH6725 Modified Amine Curing Agent

Shanghai Handai Chemical Officially Launches Its 25th Innovative Product of 2026: HYH6725 Modified Amine Curing Agent.

As a high-performance cycloaliphatic polyamine curing agent specifically engineered for epoxy resin systems, this product delivers outstanding comprehensive performance, offering a new solution for high-end coating and industrial protection applications.

HYH6725 boasts several core advantages: it exhibits excellent yellowing resistance, maintaining stable coating color and clarity even under prolonged UV exposure, effectively extending the service life of the finish. The product offers a long pot life, providing ample time for on-site application and adjustments, significantly reducing application errors and enhancing project quality. Its low-viscosity design ensures excellent fluidity, easy stirring, and mixing, substantially improving coating efficiency. It is suitable for both automated and manual application scenarios, balancing efficiency and results.

The product is a transparent liquid with a viscosity of 150–220 CPS at 25°C and an amine hydrogen equivalent of 93. It ensures precise mixing ratios, stable reactions, and excellent compatibility with mainstream epoxy resin systems, forming a dense, uniform, and strongly adherent coating after curing.

Thanks to its stable and reliable performance, HYH6725 is widely applicable in topcoat and clear coat systems, mortar and self-leveling systems, as well as various industrial and protective coating systems. It is particularly suitable for industrial scenarios demanding high weather resistance, long-lasting appearance, and extended workability, providing solid support for high-quality projects.
