DPGDA Reactive Diluent for UV Wood Coatings
CAS Number: 57472-68-1
Dipropylene glycol diacrylate (DPGDA) is a difunctional reactive diluent widely used in UV-curing wood coating formulations to reduce viscosity while maintaining crosslink density and cure speed. It provides a balance of flexibility and hardness in cured films, with good adhesion to wood substrates. DPGDA is one of the most commonly used reactive diluents in UV wood floor and furniture coatings.
