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.
