Glas-Email für gehärtetem Glas

Tempering temperature: 680 720Deg. C Firing temperature: 600 650 Deg. C Paste-oil ratio: Powder lot: Varnish (8006) = 10.3 0.35 If paste is adhered on the screen when printed, we suggest adding a small amount of thinner (801902) into the paste to adjust the viscosity and ensure a sustained printing. Coefficient of Thermal Expansion (CTE)(85 95)×10-7/K50-300 Acid and alkali resistance Acid resistance: The surface is eroded but can still clearly reflect images after dipping in 3.5% hydrochoric acid solution for 10-15min at room temperature. Alkali resistance: No sharp trace on the surface after dipping in 10% caustic soda solution for 10-15min. Supply Mode: Powder, Printing ink
