Bluesil RTV 3825 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.
At 23°C RTV 3825 will cure in 15h. In order to achieve the best possible performance levels from the pads; it is preferable to wait for 72 h before using them.
|BLUESIL RTV 3825 may be stored at a temperature between -20 °C/ -4 °F and 30 °C/ 86 °F for up to 9 months from its date of manufacturing.||Please consult the Safety Data Sheet of this product.|
