Shanghai Handai Chemical Expands Its 2026 Series with the 20th Innovative Release: HYH6720 Cycloaliphatic Amine Curing Agent

Shanghai Handai Chemical Expands Its 2026 Series with the 20th Innovative Release: HYH6720 Cycloaliphatic Amine Curing Agent.Developed for extreme temperature applications, this high-performance curing agent addresses critical coating challenges in specialized environments with its core advantages of being virtually bloom-free and offering early water spot resistance. It provides the industry with an innovative solution that combines both stability and reliability.

The product is a transparent liquid with precisely optimized key technical parameters: viscosity is controlled between 900–1300 cps at 25°C, and the amine hydrogen equivalent is 116. This excellent parameter compatibility ensures strong synergy and reactivity with resin systems. It also offers remarkable application versatility, easily adapting to different process requirements. With a shelf life of up to 24 months, it significantly reduces warehousing and inventory management costs for enterprises. It is particularly suitable for high-solid coatings and flooring systems that demand stringent color stability and chemical resistance.

HYH6720 covers a wide range of applications and can be effectively used in self-leveling floors, troweled and pebble finishes, chemical-resistant mortars and grouts, high-solid coatings, secondary protective linings, and tile grouting. Whether in freezing low-temperature construction conditions or harsh high-temperature service environments, the product performs consistently, ensuring long-term protection for coatings and cementitious materials.

Shanghai Handai Chemical remains steadfast in its corporate philosophy of “Innovating for a better life,” driving product upgrades through continuous technological iteration to create core value for customers and support the industry’s green and efficient development.
