Urethane (meth) acrylate resin composition and coating material using the same
Abstract:
The present invention aims to provide a urethane (meth)acrylate composition that forms a coating film with excellent surface-drying property at ordinary temperature through four seasons, slidability, and pinhole resistance (formation of a coating film that is free from pinholes), and a coating material using the urethane (meth)acrylate composition. The present invention provides a urethane (meth)acrylate resin composition including a urethane (meth)acrylate resin (A), a polymerizable unsaturated monomer (B), a paraffin wax (C), and an ethylene-α-olefin co-oligomer (D). The mass ratio of the paraffin wax (C) to the ethylene-α-olefin co-oligomer (D) is 0.05 to 50. The present invention also provides a coating material using the urethane (meth)acrylate composition.
