Remix each of the two components (base and catalyst) every time before using.

1. Mixing of the two components
To 100 parts of BLUESIL RTV 3220 LV add 5 parts by weight of BLUESIL CATA 2H. The two components are thoroughly mixed either 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
After mixing BLUESIL RTV 3220 LV and BLUESIL CATA 2H, it is recommended to eliminate entrapped air.
The catalysed BLUESIL RTV 3220 LV is degassed under a vacuum of 30 to 50 mbar. Under vacuum, the product expands 3 to 4 times its initial volume and forms bubbles on its surface. These bubbles will disappear gradually and the mixture will sink back down to its initial volume within few minutes. Release the vacuum and repeat the operation a few minutes later.
Remark: release the vacuum several times imes the degassing. For easier degassing only fill a recipient to 1/3 of its height


3. Cross linking
The best curing conditions are at 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. As opposed to this, lower temperatures and relative humidity levels will increase the pot life and decrease the setting rate.
It is suggested not to place the catalysed product, during or after crosslinking, to temperatures above .
At 23°C and 50% relative humidity, the moulds can be demoulded after 3 hours. In order to achieve the best possible performance levels from the moulds, it is preferable to wait for 24 hours before using them. The definitive properties will be acquired after 3 days.

4. How to use
Apply BLUESIL RTV 3220 LV mixed with CATA 2H directly on the model by casting, trying to avoid bubbles and voids.
Models can be made of several materials, stones, concrete, metal, etc. Even though silicone is naturally no-adhering to most materials is always recommendable to prepare the model to avoid any risk of the silicone sticking and so damaging the model. Remove dust and apply a pore filler like soapy water, waxes diluted in xylene, etc.
Part used drums should be resealed between each use.

STORAGE t < +40°C IN ITS ORIGINAL PACKNo special storage precautions noted. Material is stable under normal conditions. Avoid contact with oxidizing agents. Suitable containers: polyethylene. Plastic lined steel drum.Please consult the Safety Data Sheet of this product.

BLUESIL RTV 3220 LV

BLUESIL RTV 3220 LV is a silicone elastomer which cures at room temperature by a polycondensation reaction.
After the addition of catalyst BLUESIL CATA 2H, it cures at room temperature and leads to flexible and elastic material.
