It is advised to remix both base and catalyst before mixing them together.


1. Mixing of the two components
To 100 parts of BLUESIL RTV 3310 add 5 parts of catalysts BLUESIL CATA 6H or BLUESIL CATA 24H. 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 temperature rise.


2. Degassing
After mixing base and catalyst, it is recommended to degas to eliminate entrapped air. If the processing is done with the help of a machine both parts are degassed before mixing. The BLUESIL RTV 3310 is degassed under vacuum pressure of 30 to 50 mbar. Under vacuum pressure, the product will expand 3 at 4 times its initial volume and forms bubble on its surface. These bubbles will disappear gradually and the mixture will sink back down to its initial  volume within 5 to 10 minutes. Release the vacuum and repeat the operation a few minutes later.
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 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 time. 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 de-moulded after 16 to 24 hours. In order to achieve the best possible performance levels from the membranes, it is preferable to wait for 24 hours before using them. The definitive properties will be acquired after 3 days.
Remark: Part used drums should be resealed between each use.

4. How to use
Apply BLUESIL RTV 3310 mixed with BLUESIL CATA 6H or BLUESIL CATA 24H directly on the model by casting, trying to avoid bubbles and voids. Even though silicone is naturally no-adhering to most materials, it 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.

Please consult the Safety Data Sheet of this product.

BLUESIL CATA 6H

BLUESIL RTV 3310 is a silicone elastomer which, after the addition of catalysts BLUESIL CATA 6H or BLUESIL CATA 24H, cures at room temperature by a polycondensation reaction and leads to a flexible and elastic material.

2 Part RTV

Fluid

  • Easy demolding thanks to the intrinsic release properties of silicone elastomers.

  • Excellent reproduction of details.

  • Easy processing.

  • High flexibility and mechanical resistance.

Very flexible molds for the production of parts in common reproduction materials, such as plaster, wax, resins (epoxy, acrylic, polyester):

  • Decoration items: picture frames, ornaments, statues.
  • Figurines, toys, candles, giftware.
  • Furniture parts.
