PU Hardener

Kabasph® aromatic polyisocyanate hardeners deliver fast drying, high hardness, and low free TDI (≤0.5%) for 2K PU wood and furniture coatings. Ideal for interior wood finishes, matte topcoats, high-gloss clear coats, and industrial furniture production lines. High solids, low viscosity options available. China AAB Industry Technology Group, is a technology-driven high-tech group focused on green chemicals through an “investment + empowerment” dual-engine model; its main products include high-performance resins, eco-friendly pigments and pre-dispersions, specialty fillers, and functional additives, providing systematic solutions for global coatings, inks, powder coatings, and other applications. Its competitive advantages lie in a globally synergistic industrial matrix across Asia, Europe, the Middle East, and the Americas, R&D and smart manufacturing, joint innovation platforms with universities and research institutions, full-cycle support in capital, technology, channels, and management for portfolio companies, and long-term strategic partnerships with multiple Fortune 500 companies.

Kabasph® KFB-3375D is a low-free, low-odor, high-compatibility blocked HDI crosslinker delivering excellent flexibility, adhesion, and chemical resistance for can & coil coatings, flexible packaging adhesives, and industrial finishes.

Kabasph is dedicated to the research, development, and production of high-performance curing agents engineered to extend coating service life, deliver exceptional anti-yellowing properties, and provide outstanding chemical resistance. Our advanced curing agents—including solvent-based and waterborne polyisocyanates (such as HDI biuret and HDI trimer)—ensure long-term protection and aesthetic durability, even under demanding outdoor or industrial environments.

Kabasph® blocked polyisocyanates combine the durability of polyurethane chemistry with the simplicity of one-component processing. They offer extended shelf life, precise thermal activation, strong film properties, and formulation flexibility—making them the preferred choice for automotive finishes, coil coatings, and waterborne stoving systems.

Kabasph® HDI-based aliphatic polyisocyanates combine non-yellowing durability, chemical resilience, and mechanical toughness to provide long-lasting protection for coatings and adhesives exposed to demanding outdoor conditions.

Based on HDI, Kabasph® PUW series PU curing agent, also called PU hardener, offers water-dispersible polyisocyanates designed for waterborne coatings in the wood, industrial, and flooring applications. Additionally, they can be used in adhesive formulations to improve mechanical performance.
