Enamel for magnetic guides of electromagnet sheet, consisting of SiO2, TiO2, B2O3, ZnO, R2O (in which R is an alkali metal), also contains Co2O3. It has the compsn. 30-50 (wt.)% SiO2, 8-14% TiO2, 17-30% B2O3, 8 12% ZnO, 6-18% R2O and 0.8-2.5% Co2O3. It can also contain 0.1-1% Fe2O3, 0.1-0.7% Al2O3 and 0.1-0.7% CaO. Used in the electronics, radio and electrical industries. The enamel has very high electrical insulating properties and high adhesion to sheet steel. It is suitable for use on the industrial scale. In an example, an enamel had the compsn. 35% SiO2, 10% TiO2, 28% B2O3, 10% ZnO, 15% Na2O and 2% Co2O3.
