Polyester Urethane Methacrylates
Polyester Urethane Methacrylates are most commonly used in applications where low shrinkage and excellent adhesion are required. Polyester Urethane Methacrylates give slower cure response and therefore need to be formulated accordingly. They are the preferred oligomers compared to their acrylate counterparts for applications requiring ultra-low skin sensitivity.
