Shanghai Handai Chemical Unveils Its 22nd Innovative Product for 2026—HYH6722 Modified Amine Curing Agent Makes a Heavyweight Debut

Handai Chemical, with years of expertise in epoxy materials and driven by technological innovation, proudly introduces the 22nd  product of its 2026 series—the HYH6722 Modified Amine Curing Agent.

As a versatile curing agent combining broad applicability and specialized performance, HYH6722 is suitable for multiple core fields. It perfectly adapts to diverse application scenarios, including self-leveling finishes, quartz sand flooring systems, chemical-resistant mortars and grouting materials, high-solid coatings, secondary impermeable linings, and tile grouting. Whether for wear-resistant flooring in industrial plants, anti-corrosion projects in chemical workshops, or decorative finishes in high-end buildings, it achieves efficient compatibility, truly delivering the practical value of 'one agent for multiple uses' and simplifying procurement and construction processes for clients.

The product features a green, eco-friendly formula free from phenols and nonylphenol, strictly aligning with current industrial requirements for green production and environmental compliance. It has extremely low free amine content and a mild odor, improving the application environment at the source and safeguarding the health of workers. Leveraging advanced molecular modification technology, the product achieves a leap in performance, combining high reactivity with low viscosity. Its viscosity is precisely controlled at 160–260 CPS at 25°C, offering far superior flowability compared to traditional products, ensuring easy mixing and spreading, and significantly reducing application difficulty and time costs. With an amine hydrogen equivalent precisely set at 93, it enables accurate mixing ratios with epoxy resins, ensuring efficient and thorough curing reactions, notably shortening project timelines and facilitating rapid delivery.

The cured film is dense, uniform, and pore-free, with exceptional adhesion and outstanding early water resistance, effectively resisting moisture erosion. It also exhibits excellent resistance to chemical corrosion, acids, and bases, capable of withstanding long-term exposure to various media such as organic acids, inorganic alkalis, and industrial solvents. Even under extreme conditions like high humidity or strong corrosion, it maintains stable performance, significantly extending substrate service life and reducing long-term maintenance costs. The product appears as a clear, transparent liquid, and the cured film boasts a rich gloss and uniform color, balancing excellent decorative appeal with superior durability. This precisely meets the dual stringent demands of high-end projects for both performance quality and aesthetic appeal.

Adhering to its corporate philosophy of 'Innovating for a better life,' Handai Chemical remains committed to creating greater value for customers through continuous technological breakthroughs and product upgrades, contributing to the green and efficient development of the industry.
