Remix each of the two components (parts A and B) every time before using.
The instructions below are valid for both versions of the product (referred to as BLUESIL RTV 3436 A&B).
1. Mixing of the two components
Add 10 parts of BLUESIL RTV 3436 B to 100 parts of BLUESIL RTV 3436 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 3436 A&B, it is recommended to eliminate entrapped air. If the mixing is carried out by means of a machine, both parts have to be degassed before mixing.
The BLUESIL RTV 3436 A&B is degassed under a vacuum of 30 to 50 mbar. Under vacuum, the product expands 3 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 5 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 23°C. The use of products 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 rate. It is recommended not to polymerize the product at temperatures below 20°C; under these conditions, the final product performance levels will be difficult to achieve.
Room temperature curing assures the lowest possible shrinkage, if accelerated cure is desired, mild heat should be preferred. To minimize shrinkage the elastomer should be cured at maximum temperature of 60°C, higher temperatures will cause higher shrinkage.
At 23°C, the moulds can be demoulded after 16 hours. In order to achieve the best possible performance levels from the moulds, it is preferable to wait for additional 24 hours before using them.
Be aware that contact with certain materials can inhibit the curing of this RTV:

  • Natural rubbers vulcanized with sulphur
  • Polycondensation RTV catalysed with metal salts
  • PVC stabilizing agents
  • Amine cured epoxies
  • Sulphur containing clays.
If doubts exist it’s recommendable to run a quick test with a small quantity of material in order to assess compatibility. Take duly note that cross contamination due to not well cleaned tools or devices is frequently the main cause of inhibition. The best way is to use only dedicated gear when processing polyaddition RTVs.

 

STORAGE t < +40°C IN ITS ORIGINAL PACKStore in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures. Store in tightly closed original container. equipped with a degassing device. Suitable containers: polyethylene. Steel drums coated with epoxy-resin.Please consult the Safety Data Sheet of this product.

BLUESIL RTV 3436 A TRANSLUCENT

The BLUESIL RTV 3436 A&B – is a two component, silicone elastomer which cures at room temperature by a polyaddition reaction (10:1 ratio).
The product is available in two color versions:
BLUESIL RTV 3436 A&B: Red
BLUESIL RTV 3436 TL A&B: Colorless

2 Part RTV

Fluid

- High fluidity.
- Easy processing and curing.
- Excellent mechanical properties.
- Low linear shrinkage (when cross-linked at room temperature).

This product is specifically formulated for the production of flexible moulds to be kept for long periods or where particularly accurate reproduction is required (ceramics, figurines, model-makers, etc.).
