Sealing of moisuture and gases - PLENSET™ Gas barrier type

What is the PLENSET_TM gas barrier type?

PLENSET_TM Gas Barrier Type is an innovative one-component epoxy resin adhesive developed utilizing the advanced technological capabilities of Ajinomoto Fine-Techno.
This product maintains the excellent low-temperature curing properties of the traditional PLENSET while incorporating additional functionality as a gas barrier. It is designed to achieve a composition that is resistant to the infiltration of water vapor and other gas components. Consequently, during sealing, it effectively prevents the entry of harmful gases and moisture from the outside, significantly enhancing the performance and longevity of the sealed parts.
This feature plays a crucial role in many fields, including electronic components, precision machinery, sensor modules, and optical equipment.
