Nolifrit Ground Coat Porcelain Enamel Frit Features:
1, With very good adhesion, can dissolve much iron oxide in metal surface, makes very strong combination with metal body.
2, Can be combined with cover coat in high level.
3, With very good elasticity and compressive strength. Prevent and decrease damage due to mechanical stress.
4, With less viscosity and surface tension, it's good for escape of gas when firing. Reduce bubbles on cover coat. To ensure the smooth surface of enamel products.
5, With suitable expansion coefficient similar as steel plate.
Steel Plate Ground Coat Porcelain Enamel Frit Usage Introduction:
Steel plate ground coat frit is mainly used in low carbon steel plate, with very good adhesion and wide firing temperature range.
It can be single used, and can be also mixed with other ground coat frits according to firing temperature required.
