∎Typical Applications

Provide a glassy clear appearance to parts manufactured using it. The rubber is an excellent candidate to consider for cost-efficient

manufacture of highly transparent optical parts, with very low modulus.

How to use ?

Remix each of the two components (part A and B) every time before using.

● Mixing of the two components

  1. Add 100 parts A to 100 parts B.

  2. 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. 

  3. The viscosity of part A and B can be reduce using Maxtech  2300, add 5 to 10% of the quantity of SI8601. This will make no significant change to the mechanical properties after polymerization. Up to 30% of Maxtech 2300 can be added without causing exudation.

  4.  Degassing

  5. After mixing base and catalyst, it is recommended to eliminate entrapped air.

  6. If the processing is done with the help of a machine both parts are degassed before mixing.

  7. The SI8601 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. Wait a few minutes to ensure complete degassing and then release the vacuum. The product is ready for use.

  8. Remark:  release the vacuum several times improves the degassing.  

  9. For easier degassing only fill a recipient to 1/3 of its height.

  10. The product can be poured by gravity or under pressure. SI8603 A and B is easier to use than normal RTV because the viscosity of the two components Increases relatively slowly.

  11.  Cross-linking

  12. At 23°C, the moulds can be demoulded after 24h. In order to achieve the best possible performance levels from the moulds it is preferable to wait for 24 h before using them.

  13. If the accelerated cure is desired, mild heat should be preferred. Conversely at lower temperature polymerization is much slower, at 20°C 36h may be necessary to complete cross-linking.

  14. Be aware that contact with certain materials can inhibit the curing of this RTV:  

  15. Natural rubbers vulcanized with sulphur

  16. Polycondensation RTV catalyzed with metal salts

  17. PVC stabilizing

  18. gents Amine cured

  19. epoxies Sulphur

  20. containing clays.

  21. In case of doubts, it is recommended to test the substrate by applying a small quantity

  22. of the mixed silicone on a restricted area. Take note that cross contaminates due to improperly cleaned tools or devices are a most frequent cause for inhibition
