Remix each of the 2 components (base and catalyst) every time before using.
1. Mixing of the two components
To 100 parts of BLUESIL RTV V-1062 S add 10 parts of BLUESIL CATA HI PRO GREEN.
The two components are thoroughly mixed either by hand or using an electrical or pneumatic mixer, on a low speed setting so as to limit the inclusion of air in the mixture as well as the temperature rise.

2. Degassing
The mixture is degassed under a vacuum of 30 to 50 mbar. The product will expand under the action of the vacuum to between 3 and 4 times its initial volume and bubbles form on its surface. These bubbles will disappear gradually and the mixture will sink back down to its initial volume within 5 to 10 minutes. Releasing the vacuum once or twice during the operation will improve and facilitate gas removal.
Remark: release the vacuum several times improves the degassing. For easier degassing only fill a recipient to 1/3 of its height.

3. Cross linking
The best curing conditions are at 23°C and 50 % relative humidity. The use of the products at higher temperatures and / or relative humidity levels will reduce the pot life and increase the setting rate. However, the temperature must not exceed 50°C beyond this temperature there is risk of the product reverting. As opposed to this, lower temperatures and relative humidity levels will increase the pot life and decrease the setting rate. It is recommended not to use the product at temperatures below 20°C under these conditions, the final product performance levels will be difficult to achieve.

At 23°C and 50 % relative humidity, the membranes can be demolded after 16 h-24 h. In order to achieve the best possible performance levels from the membranes, it is preferable to wait for 24 h before using them. The definitive properties will be acquired after 3-7 days.
The recipient containing the catalyst must be carefully closed after use air moisture causes a reduction in its reactivity over time.
Ensure that the packaging is hermetically sealed again each time it is used.
