Testing of the Light Transmittance of Industrial Varnishes

Abstract

The article presents the study of the light transmittance of a colorless car varnish. The varnish was tested at different temperatures for UV light transmission and the ability to protect car paint pigments from degradation. These tests make it possible to assess the durability and quality of the varnish. A comparison of light transmittance through glass, quartz glass and solar glass was made. It has been noted that the curing temperature of the varnish has an impact on its transmission (up to a few percent). A similar effect has been observed in the case of varnish with a hardener.
