    Great Silicone
    As listed, this is a high temperature RTV silicone which can withstand high temperatures easily. I used it in my 3D printer which gets around 110C and this silicone had no problems handling those temperatures. Great product by loctite. And most of all, it’s easy to get in India at a reasonable price. Shipping and delivery was quick and the product was packed nicely.


We require a gasket that can withstand very high pressures. Can we use Loctite Gasketing solutions?
Yes, LOCTITE Anaerobic Gaskets can resist pressure upto 34.47 N/mm2.
Our design uses the pre-cut gasket as a shim. Is there any way to use Loctite Gasket in case the gaps between the flanges are large?
Yes, in case the product design specifies the use of pre-cut gasket as a shim, LOCTITE Anaerobic Gasket Dressing can be used in conjugation with the pre-cut gasket. Just clean the flange surfaces and apply LOCTITE Anaerobic Gasket Dressing to both the sides of a fresh pre-cut gasket. Make sure to use a primer on both the sides of the pre-cut gasket before application of the Gasket Dressing.
What type of materials can LOCTITE gasketing compounds be used on?
LOCTITE gasketing sealants can be used on many different materials including metals, wood, rubber, plastic, ceramics, glass and even concrete. The type of sealant selected for a specific application depends on the material to be sealed, environmental conditions, temperature and operating pressures in the system.
There are some traces of the old gasket left on the parts. What can be used to remove them?
In order to remove any old gasket parts, you can use LOCTITE SF 790 Chisel Gasket Remover.
We have to seal a fuel system. Would LOCTITE gasketing compounds be effective?
Yes. LOCTITE has two types of gasket technologies - one is anaerobic and the other is high performance Silicones. LOCTITE Anaerobic Gaskets are resistant to gasoline and Fuel oils. LOCTITE High Performance Silicones are 8 times more oil resistant than standard RTV silicones and hence perform well when used to seal hot oil systems like oil pans. They are both definitely superior to ordinary silicones as the latter swell and loose their sealing ability when used to seal fluid systems.
How can we disassemble a part sealed with LOCTITE Gasketing Compound?
In order to disassemble the flanges sealed with LOCTITE Gasketing Compound, just use hand tools, and clean the flange surfaces with LOCTITE SF 790 Chisel Gasket Remover.
