Remix each of the two components (part A and B) every time before using.
1. Mixing of the two components
Add 100 parts of BLUESIL RTV 3530 A to 100 parts of BLUESIL RTV 3530 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 as well as the temperature rise.
2. Degassing
After mixing base and catalyst, it is recommended to eliminate entrapped air.
If the processing is done with the help of a machine both parts are degassed before mixing.
The BLUESIL RTV 3530 is degassed under a vacuum of 30 to 50 mbar. Under vacuum, the product expands 3 at 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 5 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. 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 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, the moulds can be demolded after 24 hours. In order to achieve the best possible performance levels from the moulds 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.
Conversely at lower temperature polymerization is much slower, at 36 hours may be necessary to complete cross-linking.


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 is 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 causes of inhibition. The best way is to se only dedicated gear when processing polyaddition RTVs.
