TECHNOLOGY

The GLS enamel is a critical component. It's not just any glass; it's a specially formulated borosilicate glass frit designed to have a coefficient of thermal expansion similar to that of the steel substrate.

This similarity minimizes stress at the glass-steel interface during temperature fluctuations, preventing cracking and spalling.

The enamel is also formulated to resist attack from a wide range of chemicals, including acids (except hydrofluoric acid), alkalis, and solvents. Different enamel formulations are available for specific applications, such as high-temperature service or exposure to particularly aggressive chemicals. The quality of the enamel is determined by factors such as its chemical composition, particle size distribution, and fusion characteristics.
