RTV 3122 tends to settle during storage, and must be rehomogenised before use. This should be done directly in the original container, either by hand with a spatula, or mechanically with a stirrer.

Be taken to entrap carefully with little air when the catalyst is added, as it would cause bubbles in  the finished product. It is therefore advisable to degas the mixture under a vacuum of 30 to 50 mbar in three to five minutes, applying the vacuum twice in the chamber.  Degassing is quicker in a container with a high diameter: height ratio.

3.Cross linking
At 23°C RTV 3122 will cure in 15h. In order to achieve the best possible performance levels, it is preferable to wait for 72 h before using them.

BLUESIL RTV 3122 may be stored at temperatures between -20°C / -4°F and 30°C / 86°F for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


Bluesil RTV 3122 + 2% Catalyst 68 is a silicone elastomer with two components, crosslinking at room temperature by a polycondensation reaction.
