INTRODUCCIÓN DEL PRODUCTO

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.
