Steps to Apply RTV2 Moulding Silicone

Steps to Apply RTV2 Moulding Silicone

1) Surface (Model) that silicone will be poured must be clean.

  •    There shouldn’t any wet, dust or dirt.

2)    Release agent for the surface is adviced.

  •    Spray    

  •    Brush    

  •    Sponge

3)    Silicone must be mixed at least 30 seconds before adding the curing agent.

  •    Mixing process will increase the fluidity of the silicone.

  •    Helps chemical components inside the silicone become homogeneous.

4)    All preliminary work should be done before casting and casting should be completed without wasting time.

  •    Enough amount of curing agentmust be added to silicone.

  •    Ideal curing time that depends on the silicone and curing agent. In most of the cases it is better to wait for 8-12 hours. Silicones that vulcanized (cured)under or over this time may have slightly less performance.

  •    Curing agent amount must be set according to the ambient temperature and moisture.

  •    Curing and operation time shortens as the temperature and moisture rises.

  •    More the curing agent amount faster the vulcanizing, less the curing agent amount slower the vulcanizing.

  •    Precision balance is highly recommended to determine the right amount. If there is no access to any balance, tape measure or a syringe can be used, as well.

5)    Silicone must be mixed well after adding the curing agent.

  •    A low-medium speed mixer (paint mixer etc.) is recommended.

  •    Mixing process, taking the silicone amount into consideration, should continue approximately for 1-2 minutes.

  •    Important during the mixing process is to make sure that the curing agent penetrates the siliconecompletely and spreads homogeneously.

6)    Removing of the air bubbles after the mixing process is essential.

  •    Must be kept for 1-2 minutes inside the vacuum chamber for the best results.

  •    If you have no access to a vacuum chamber one, vibration method can be used.

  •    With a blowgun or by blowing, the evacuation of bubbles on the surface can be supported.

7)    Silicone must not be touched after the moulding process until the vulcanizing (curing) is completed.

  •    Vulcanized silicone can be released from the model.

  •    For the best moulding performance, process should begin at least 24 hours after the vulcanizing is done.

  •    It is recommended to rest the mould and cleaned at regular intervals between the castings if the offensive chemicals will be processed such as polyurethane.
