Remix each of the two components (parts A and B) every time before using.
1. Mixing of the two components
Add 10 parts of BLUESIL RTV 3430 SB B to 100 parts of BLUESIL RTV 3430 SB A.
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 3430 SB A&B, it is strongly recommended to eliminate entrapped air. Any air bubble included in the cured silicone mold represents weakness points of the mold itself, decreasing both its mechanical resistance and the resistance to diffusion of the casting material inside the mold.
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 3430 SB 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.
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, the elastomer can be cured at a temperature of "

  • Very good release properties.
  • High mechanical strength.
  • Excellent details reproduction.

This product is specifically formulated to produce silicone molds having very good release properties the molds can be used therefore for the production of manufacts (e.g. ornamental or decoration parts) made of casting materials requiring careful demolding.
