|
|
Non-solvent Type ( Silicon Type) 1211
|
-
It is low in viscosity and is fluidity. Thus, it is superior in workability
-
It can be used in combination with solid sheet gasket for temporary fixing of the O-ring
-
As it corrodes copper and copper alloy, It cannot be used on copper or copper alloy under airtight state
Three Bond 1211 is a silicone based, one component white coloured liquid gaskets. It sets automatically at room temperature upon exposure to air moisture. No hardeners, activators or heat are required. TB 1211 increases bonding strength while hardening. They begin hardening in 40 minutes at 25ºC after application. The resultant rubber-like solids resist both heat and cold, maintains stability and original properties under a wide range of temperature.
Features
-
Highly resistant to heat, cold, weather
-
Excellent electric insulation
-
Solvent-less; minimal shrinkage
-
Ideal for sealing comparatively large clearances
