Properties of UV-Curable Coatings for Wood Floorings as a Function of UV Dose
E-mail:
We have investigated the viscoelastic properties and strengths of cured films of UV-curable urethane acrylate coatings as a function of the UV dose. In this study, the value of Tg increased with increasing UV dose, but the logarithmic damping ratio, which is related to the hardness, decreased accordingly. The tensile strengths increased with increasing UV dose. For the aliphatic and aromatic urethane triacrylate coatings, there was no significant improvement in the tensile strength over 0.44 J/cm2. For the mixture of aliphatic and aromatic coatings (50:50 wt%), the tensile strength increased with increasing UV dose up to 0.74 J/cm2.
