JONCRYL^® U 4500

Polyurethane Dispersion for High-End Wood Applications

JONCRYL U 4500 is a new self-crosslinking, aliphatic polyurethane dispersion designed for use in wood topcoats. The dispersion is characterized by its final hardness and exceptional scratch resistance. The dispersion is free of both triethylamine and NMP. Additionally, the low minimum film forming temperature and low solvent demand allows formulators to achieve low VOC coatings. With its broad acrylic dispersion compatibility, JONCRYL U 4500 can be easily blended with WB acrylic resins such as JONCRYL 9530-A to achieve higher levels of scratch, mar, and abrasion resistance, without many of the potential drawbacks of PUD blends.
