What is Molecular Adhesion Technology

Molecular adhesion technology is the means for providing a strong adhesion between rubber and various other materials such as metal, resin, ceramics, glass, and different kinds of rubber.
By using adhesion surface treatment and heat/pressure, this technology provides a strong adhesion without high-density adhesives or conventional high temperature/high pressure adhesion processes.

Features of Molecular Adhesion Technology

  1. Ultra-fine grooves and fluid channels that have been etched in plastics, etc. can be sealed without being filled.
    (This is due to the molecular film being close to a monolayer, even if a molecular adhesive is used.)

  2. Molecular adhesion is conducted at a temperature that does not exceed the melting point of the target materials, thus reducing the risk of deformation.
    (Unlike heat sealing with plastics, adheasion temperature is 80°C or lower.)

  3. Molecular adhesion enables adhesion between silicone rubber and difficult to adhere plastics.
    (This is the strongest feature of molecular adhesion technology. For optical detection applications, it is essential to have a flat, clean surface free of residual adhesive.)

Examples of Work Process


Characteristics of PDMS (Silicone Rubber)

  1. Air bubbles can be eliminated from liquids due to silicone's excellent air permeability.

  2. Advantageous over conventional resins in terms of heat resistance, UV resistance, and weather resistance.

  3. The shape of the silicone rubber can be changed by using external stress.
    (Swelling, expansion: Applicable for valves)
