BLUESIL RTV 3044 A may be stored for up to 18 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.

BLUESIL RTV 3044 A

Bluesil ™ RTV 3044 is a 1:1 mix ratio, two-component clear, high strength, addition cure silicone rubber compound. It is formulated to cure overnight at room temperature or within hours at elevated temperature to give a hardness of approximately 38 ShA. Its low viscosity makes the product easy to pour and quick to degas.

  1. Stir both components A and B well before use (except when machine dispensing).

     
  2. The components A and B are mixed by weight in the above indicated ratio into a clean mixing container until a uniform color is obtained, making sure to scrape the container walls and bottom to ensure a thorough mix.  The mixing can be carried out either by hand or by using a low speed electric or pneumatic mixer to minimize the introduction by air and to avoid any temperature increase.  If a mechanical mixer is used, do not exceed 150 rpm..

     
  3. Place the container into a vacuum chamber and evacuate the entrapped air from the mixture using a vacuum pump capable of achieving 29 inches of mercury vacuum. The mixture will rise, crest and then collapse in the container. Interruption (bumping) of the vacuum may be necessary to prevent overflowing the container. Keep the mixture under full vacuum for 2-3 minutes after the material has receded in the container.

     
  4. Bleed air slowly into the vacuum chamber. When the chamber is at atmospheric equilibrium, remove the cover plate and take out the container.

     
  5. Pour the deaired material slowly in a steady stream from one end of the mold box so that the material flows evenly over the pattern. This should minimize entrapment of air bubbles under the flowing material. A "print" coat may be poured first over the pattern which will also help reduce the possibility of entrapping air on the pattern and in the cured rubber. A mold release (petroleum jelly) may be applied on the pattern first to improve release.

     
  6. Allow the rubber to cure for 16-24 hours at 75±5°F (24°C) before removing the cured rubber mold from the pattern. For best results, allow the mold to air cure an additional 24 hours before using it in production. Full cure is achieved in 3-7 days.

     

    MIXED PROCESSING PROPERTIES WILL BE AFFECTED

    BY TEMPERATURE VARIATIONS

     
  • A decrease in work life and pot life may be expected to occur at temperatures exceeding 75°F (24°C). Room temperature curing moldmaking rubbers are particularly sensitive to higher temperatures. Refrigeration of the base (Part A) prior to use in hot environments has shown to improve the handling properties of these materials.
  • Lower temperatures will increase the work life and pot life of this material. Cure temperatures below 68°F (20°C) are not recommended and have been found to cause a reduction in final cure hardness and physical properties.
  • This system contains a platinum CATALYST, which may be inhibited by materials found in some organic polymer systems, chlorinated solvents, and some substrates. Especially troublesome materials are: amine cured epoxies, sulfur cured organic rubber systems such as natural rubber, polysulfide rubber, latex rubber and adhesives, sulfur containing modeling clays, PVC coated surfaces, and tin catalyzed silicone RTV rubbers. A patch test to determine compatibility is recommended when doubts exists
