Gaskets are substrates, typically foam, rubber or paper, that act as an interface or seal between two surfaces. They are found throughout industry, but are especially common in electronics, transportation, fluid handling and appliances. Their assembly requires resistance to a number of fluids, high adhesion to difficult-to-bond surfaces, and fast and easy application. Bonding a Gasket to substrate comes in handy for assembly.
Because gaskets are often held in place with pressure and friction (O-rings, for example) a true “bond” may not be required. In applications such as these, adhesive bonded gaskets are most commonly placed in compression stress.
The primary function of the adhesive or tape is to seal and permanently bond the gasket should the two different parts be separated. For gaskets with exposed edges or applications requiring frequent separation (e.g. refrigerator doors), peel stresses become prominent. Gasket material is often very flexible, and adhesives and tapes with high peel strengths are required.
