Liquid Gaskets are liquid sealants used for sealing inner fluids by applying them to the joint surfaces of various flanges, screws etc. Highly reliable sealing is achieved by filling in and adhering to the minute clearance on the joint surface. As they are a liquid when applied, so metal joint surfaces touch each other, and there is almost no decrease in surface pressure due to vibration. Therefore, they are durable and have excellent sealability. Products with various material bases are available including synthetic resin-based, synthetic rubber-based, acrylate-based, acrylic emulsion-based, and silicone-based. There are also various reaction system grades including solvent vaporization, anaerobic curing, and moisture-curing.
Products include general-purpose types, and products for FIPG and CIPG.
FIPG: Formed In Place Gasket Liquid gasket that is applied on one surface and forms a seal by reactive curing after joining the other surface.
CIPG: Cured In Place Gasket Liquid gasket that is applied on one surface as a bead and forms a seal by curing before joining the other surface (sealing by surface pressure of the joint surface).
TB1207B is an acetone type single-component, moisture-curing, silicone-based liquid gasket for FIPG. It has a fast curing speed, and it becomes a flexible cured material, so it has excellent displacement conformability on joint surfaces. In addition to engine oil pans, it can also be used for sealing coolants such as for water pumps.
