Product advantages and working principle：
The tempered glass enamel is reinforced through high-temperature (680-720?C) instant baking and instant cooling, which melts the glass pigment and the glass body into one, achieving color adhesion and durability. After colorization and enhancement, the glass has strong structure, high strength, strong resistance to atmospheric corrosion, and good corrosion resistance and hiding power.
Matters needing attention:
1. Do not contact with the skin directly;
2. Stir thoroughly for 5-15 minutes before use;
3. Please test before mass production;
4. Immediately seal after use.
