- Application and Usage Information
- Usage Information:
- Remix each of the two components (parts A and B) every time before using.
- Mixing of the two components:
- Add 100 parts of Bluesil™ RTV 3460 A to 10 parts of Bluesil™ RTV 3460 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.
- Degassing
- After mixing BLUESIL RTV 3460 A&B, it is recommended to eliminate entrapped air. If the processing is done with the help of a mixing machine both parts are degassed before mixing.
- The BLUESIL RTV 3460 A&B 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.
- 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 molds can be demolded after 16 hours. 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 60°C for 3-4 hours, higher temperatures will cause higher shrinkage.
- Conversely at lower temperature polymerization is much slower, at 20°C 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 sulfur
- Polycondensation RTV catalyzed with metal salts
- PVC stabilizing agents
- Amine cured epoxies
- Sulfur 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.
- Product Application: This product is specifically formulated for use with casting materials and urethane foams for architectural, prototyping and furniture molding applications. Bluesil™ RTV 3460 A and Bluesil™ RTV 3460 B is also used in high pressure applications (PU Foam, RIM).
