Remix each of the two components (parts A and B) every time before using.
1. Mixing of the two components
Add 100 parts of BLUESIL RTV to 10 parts of BLUESIL RTV 3433 B.
The two components may be intimately mixed either by hand or using a low-speed electric or pneumatic mixer to minimize the introduction of air into the mixture.


2. Degassing
After mixing BLUESIL RTV 3433 A&B, it is strongly recommended to eliminate entrapped air. If the processing is done with the help of a machine and a static mixer, the two parts are degassed separately before mixing.
The BLUESIL RTV 3433 A&B 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. Then the vacuum can be released.
Remark: release the vacuum several times imes the degassing. For easier degassing only fill a recipient to 1/3 of its height.
Molds obtained without degassing the mixed A and B parts can contain voids (entrapped air bubbles) that lead to damages of the mold itself upon repeated usage with common reproduction materials. Following the degassing instructions above is therefore a method to increase mold duration.
3. Cross linking
The best curing conditions are at 23?C. The use of the product at higher temperatures will reduce the pot life and increase the setting rate. As opposed to this, lower temperatures will increase the pot life and decrease the setting time.
At 23?C, the cured silicone can be demoulded after the time indicated as ""demolding time"""""" (see § 2.Polymerization, pag.1). In order to achieve the best possible performance levels from the molds, it is preferable to wait for 24 hours before using them.
Room temperature curing assures the lowest possible shrinkage, if accelerated cure is desired, mild heat should be preferred. To minimize shrinkage cure the elastomer at maximum temperature of for 3-4 hours, higher temperatures will cause higher shrinkage.
Be aware that contact with certain materials can inhibit the curing of this RTV:

  • and its derivatives (e.g. sulphur containing clays"
