Oligomers are the bulk component of a UV/EB curable formulation and therefore determine the main properties. Urethane (meth)acrylates provides the best balance between adhesion, hardness, flexibility, weatherability, and abrasion and chemical resistance. Many of these properties are due to the intermolecular hydrogen bonding ability of urethane groups.
Urethane (meth)acrylates are suitable for high-grade interior and exterior applications. The main applications are in coatings for metals and plastics as well as coatings for high-quality furniture and flooring. They are also often used in overprint varnishes (OPVs) and offset and screen inks.
