Polyurethane Acrylate Oligomer for Flexible UV Wood Lacquer
CAS Number: 9009-54-5
Aliphatic polyurethane acrylate (PUA) oligomer for UV-curing wood lacquers provides an exceptional balance of flexibility, hardness, and non-yellowing clarity. Unlike epoxy acrylates, PUA oligomers maintain their color stability under UV light exposure, making them the preferred choice for clear topcoats and light-colored wood finishes requiring long-term appearance retention.
