Powder Glass for Coating and Binding
Powder glass is used to coat a wide variety of substrates and elements. Please make your selection using the expansion coefficient and softening point as a guide.
Powder glass is also used as a binder for thick film paste and ceramic chip devices. Please make your selection using glass type and softening point as a guide.
