Self-adhesive gaskets are covered on one side with an adhesive backing. The adhesive is protected by release paper, which is peeled away at the time the gasket is ready to be installed. The adhesive is there to help hold the gasket in place while fitting, not for any mechanical sealing or structural purpose.
Self-adhesive and pressure-sensitive gaskets are used to make fitting and installation of gaskets simpler. The adhesive helps prevent slipping or deformation of the gasket by holding it in place until flange bolts or clamps are tightened. This is especially useful when the surface the gasket is applied to is not completely horizontal, for very large gaskets that are hard to fit, or where gaskets need to be fitted quickly for safety reasons.
Adhesive backed gaskets are also useful for sealing removable panels. When the panel is removed, the gasket stays in place.
Considerations for self-adhesive gaskets
Adhesive choice can depend on a variety of factors:
- Gasket material
- Surface characteristics where the gasket will be applied
- Operating temperature
- Need for chemical or solvent resistance
- Need to reposition
The choice of release paper can also be important. Some types are flexible, others help the gasket maintain a stable shape.
