    What is Liquid Silicone Rubber?

    Liquid Silicone RTV (room-temperature-vulcanizing silicone) is a two-part system that can be mixed and poured into a mould. It cures at room temperature and can be used to create highly detailed resin art moulds.

    RTV is made up of two components: a base and a catalyst. The base is usually clear or white, while the catalyst can be either clear or pigmented. When mixed together in the correct ratio, they will react to form a cured silicone rubber. ArtSil base (Part A) is pink in colour with a blue catalyst (Part B) when mixed ArtSil will be a purple this to help to insure correct mixing. 

    The beauty of using RTV is to create moulds that can reproduce even the most intricate details. It is also very strong and flexible, making it ideal for use with resin projects.

    Once your RTV mould is created, you can use it over and over again to cast perfect copies of your original artwork. So if you're looking for a way to create professional-quality resin casts, ArtSil RTV Silicone is definitely the way to go!

    How To Make Moulds With Artsil Liquid Silicone Rubber

    When using liquid silicone to create moulds, it is important to follow the instructions carefully. The process is relatively simple and does not require any special equipment. You will need an ArtSil kit, mixing container, mixing sticks, your master and an outer mould. 

    To start, mix the liquid silicone base (Part A) and liquid silicone catalyst (Part B) with a ratio of 1:1 by volume. 

    Once mixed, pour the mixture into the mould and tap the mould on a flat surface, you can also tap the side walls, then allow it to cure for the amount of time specified on the label. Once cured, remove the mould from the cured silicone.

    Finally, clean up by cutting any excess cured silicone from the mould and you are ready to use your new mould!
