Polyisocyanate hardener stands as a cornerstone in high-performance coating formulations, offering a wide array of options tailored to diverse application needs. Runshine New Materials (Foshan) Co., Ltd. specializes in producing various polyisocyanate hardeners, ranging from solvent-based to waterborne types, and including both blocked and unblocked variants. These hardeners, also known as crosslinkers, derive from different isocyanate monomers such as HDI, IPDI, TDI, and MDI, each bringing unique properties to meet specific coating requirements. What makes polyisocyanate hardener indispensable is its unique reactivity with polyols or other active hydrogen groups, which enables the formation of robust, crosslinked polymer networks—networks that underpin the durability and performance of the final coatings.
