There is no significant difference in the general practice of porcelain restoration in China and other countries. However, there are a wider variety of commercial products specially designed for porcelain restoration in western countries. Many of those products are quite worthy of being introduced into China. In this study, we tested and studied three imported products: Hxtal NYL-1, Golden Porcelain Restoration Glaze and Golden Polymer Varnish with UVLS. Tensile test results show that Hxtal NYL-1 has the highest elongation at breakage and the lowest tensile strength among five epoxy formulations. After 78-day exposure to UV light at 365 nm, the color of Hxtal NYL-1 varies the least among three epoxy formulations. According to the UV-Vis spectra, Golden Glaze only absorbs UVB, and Golden Varnish absorbs both UVB and UVA. The results of a 7-day UV light aging experiment show that neither Golden Glaze nor Golden Varnish becomes yellow after being exposed to UV light at 365 nm, but Golden Varnish is much less prone to yellowing than Golden Glaze at 254 nm. In addition, based on some practical cases, the usage of these products in porcelain restoration is also briefly introduced in this paper.
