Abstract

The durability of an acrylic-melamine (AC-ML) based varnish containing Tinuvin 292 when exposed to 100 cycles of accelerated exposure testing in fluorescent UV and condensation was investigated. Fourier-transform infrared (FTIR) spectroscopy, thermal gravimetric analysis (TGA), and scanning electron microscope (SEM) were used to evaluate the changes between the initial and aged coatings...
