ВВЕДЕНИЕ ПРОДУКТА

The PUW series is formulated with Zero VOCs aliphatic polyisocyanates based on hexamethylene diisocyanate (HDI), enabling excellent self-emulsifying ability when mixed with waterborne polyol binders. This two-component (2K) system delivers superior chemical resistance, thermal stability, and enhanced bonding strength across diverse substrates including metal, wood, and plastic.

Key Advantages

Easy Dispersion:Directly add to waterborne resin and mix with low-speed stirring—no high-speed dispersion equipment needed; simple operation.
Fast Drying:Cures at room temperature, fast drying speed, suitable for production lines, improves efficiency.
High Hardness:Forms a hard film with good scratch resistance and anti-blocking properties, ideal for furniture, flooring, and other wear-resistant applications.
Non-Yellowing:Based on HDI aliphatic structure, resists yellowing under outdoor exposure, suitable for automotive coatings and outdoor metal finishes.
Water and Chemical Resistance:Cured film offers good resistance to water, solvents, and stains, ideal for industrial protection and kitchen/bathroom environments.
Broad Substrate Compatibility:Can be applied to various substrates including wood, metal, plastic, and concrete.

Waterbased Polyisocyanates

Based on HDI, Kabasph® PUW series PU curing agent, also called PU hardenr, 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.

Aliphatic Polyisocyanates

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.

Blocked Polyisocyanates

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.

Customized Polyisocyanates

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.

Solvent-Based HDI Blocked Aliphatic Polyisocyanate Crosslinkers

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.
