New-Dimension Adhesion Achieved with Molecular Adhesion and Bonding Technology!

Proposed Product, Service or Method

【New-Dimension Adhesion Achieved with Molecular Adhesion and Bonding Technology! 】

We have leveraged our rubber adhesion technology cultivated over many years to develop a molecular adhesion technology that is able to seal without crushing minute grooves of around several µm to several hundred µm transferred onto glass or resin. The technology is garnering attention as an innovative adhesion technology effective for the development of micro fluid devices that conduct operations such as electrophoresis, chemical reactions and cell culturing.

【Benefits】☑Reduced costs ☑Reduced size/weight ☑Shorter delivery time ☑Improved quality/performance ☐Safety/environmental measures ☐Other

Technological Distinctiveness, Sales Points, Main Features

・Differing from conventional adhesives that use intermolecular forces or anchoring effects, the rubber and base material are adhered/bonded through covalent bonds for high peel strength and exceptional heat, thermal shock and water resistance.
・There is almost no adhesive layer, so adhesion/bonding can be accomplished without eroding minute structures such as flow channels. Also, there are almost no dimension errors caused by variations in the thickness of the adhesion layer.
・Unlike fusion, adhesion/bonding is achieved at a lower temperature than the melting point of the materials being adhered, which makes it possible to limit the occurrence of warping in resins, etc. caused by deformation or thermal expansion differences.

Existing and Potential Applications

・Track record in mass production of RFID tags, human STR–analysis chips, etc.
・Developing applications for cell cultivation devices, medical devices, switches, etc.
