They are the most chemically durable of the lead-containing systems we offer for packaging applications and are especially recommended where exposure to aggressive atmospheric attack (e.g. sulfur), may be encountered.
- chemical composition: lead. Those marked * are developed with cadmium-containing pigments. - expansion coefficient (C.o.E.): Average C.o.E. measured on the basic frit System is 80 (± 4).10-7K-1. - recommended firing conditions: 600oC to 650oC - chemical resistance: Norm EN 1388-2 (tests on the basic flux system in laboratory conditions)
