Shanghai Handai Chemical Officially Unveils Its 27th Innovative Product of 2026: HYH6727 Solvent-Free Mannich Curing Agent

Shanghai Handai Chemical Officially Launches Its 27th Innovative Product of 2026: HYH6727 Solvent-Free Mannich Curing Agent.

Specifically designed for rapid curing at temperatures of 0°C and above, this product can be used directly with unmodified epoxy resins, providing a stable and efficient curing solution for epoxy systems in low-temperature working conditions.  

HYH6727 stands out with three core advantages: rapid curing, long-term durability, and environmental sustainability. The product offers excellent curing speed, significantly reducing construction wait times and improving overall project progress. After curing, it forms a dense cross-linked structure with outstanding chemical and water resistance, effectively protecting against erosion from acids, alkalis, solvents, moisture, and other harsh environments, meeting the needs of long-term industrial and outdoor protection. Additionally, the formulation contains no benzyl alcohol, featuring mild odor and low volatility for enhanced safety and environmental friendliness. It aligns with modern green construction and health protection requirements, ensuring both engineering quality and user safety.  

The product is a transparent liquid with stable properties and excellent compatibility. Its viscosity is controlled between 900–1400 CPS at 25°C, and the amine hydrogen equivalent is 90. It ensures precise mixing ratios, smooth application, and adaptability to various processes and formulation designs, offering users flexible and efficient options.  

Thanks to its well-balanced performance, HYH6727 is widely used in marine protective coatings, solvent-free flooring, civil engineering, rapid-curing adhesives, and various repair materials. It can also be used as a performance-enhancing component in combination with other amine curing agents to improve system reactivity and overall performance.  

Handai Chemical drives industry advancement through technological innovation, empowering engineering construction and industrial protection with high-quality products, and continuously providing customers with safer, more efficient, and more durable material solutions.
