Applications:

  • Designed for applications which demand a strong but flexible bond, such as when bonding materials with differing thermal expansion rates, e.g. glass to metal or glass to plastic. 
  • Unprimed adhesion to commonly used materials including enameled and painted steel, aluminum, ceramic and glass as well as to certain plastics used in engineering applications.
  • Used as a Formed-in-Place Gasket (FIPG) material.
