About Liquid Gaskets

What are liquid gaskets?

They are generally fluidic materials at room temperature. When they are applied on a joint surface they dry or become flat after a certain period of time to form an elastic membrane or viscous thin film. They keep satisfactory tightness of the jointed portion against oil, water, and air, and prevent leak of them having enough pressure resistance.

Advantages of liquid gaskets

• A small amount provides sufficient sealing.→Reduce the gasket material cost.
• Effective even on a surface with relatively low tightening pressure.→Reduce the part and material costs.
• Well adaptive to a flange surface.→Reduce the process steps and process cost.
• No additional tightening required.→Simplify the work.
• Lessens the preparatory works including material selection and calculation of thickness, compared to solid gaskets.→Shorten the design time.
• Applicable to any shape or size of flanges.→Reduce time and cost for inventory control.

Merits in installing a coating machine

• Enables automation.→Improves the production volume.
• Constancy of application amount.→Eliminates waste.
• Eliminates such variation as excessive or insufficient application.→Stabilizes quality.
• Reduces workers.→Reduces the workers cost.

Various types of liquid gaskets

What are silicone-based liquid gaskets?

Please understand the characteristics of liquid gaskets and use them accordingly.

• Pressure resistance varies depending on how clean the applied flange surface is (oily, watery, dusty, etc.).
• Non-solvent, reactive types require some time to change from a liquid to solid form; therefore, such time must be controlled.
• The removability of an adhesion type is not so good.
• Not suitable for a flange that has a very big clearance.
• Needs to use a liquid gasket that suits a medium to be sealed (oil, water, etc.)
