Ink-jet head using sealant and ink-jet apparatus using the ink-jet head

摘要

The present invention provides an ink-jet head and an ink-jet apparatus using the ink-jet head. The liquid-ink-contacting sections of the ink-jet head are sealed with a moisture-curing sealant essentially consisting of a silicone-modified organic polymer compound. In the molecular structure, the silicone-modified organic polymer compound has carbon atoms modified with alkoxysilane . The moisture-curing sealant contains an organo-tin or organo-titanium catalyst having the alkoxy and/or carboxyl groups, the alkyl chain of the alkoxy group has 5 or less carbon atoms, and the alkyl chain of the carboxyl group has 6 or less. <IMAGE>
