Clear Liquid Silicone Rubber
Applications of liquid silicone rubber
Generally speaking, transparent silicone rubber is used for making precise details products. When the master mold is very precise, and you do not want to damage the master mold, transparent silicone rubber can let you see clearly where is the joint line and let you cut the mold easily.
Advantages:
1, Great transparence.
2. Excellent mechanical properties, in particular tear strength.
3, Excellent flexibility and its low modulus facilitate the mould release.
4, Range of catalysts allows to fulfil the requirements for various curing and working time.
Instruction And Professional Guidance
1, About choosing hardness
First, if size of your stone is very large, you need to choose a little higher hardness, such as 40, 45, 50, 50…. In the contract, if size is small, just need to choose soft silicone rubber.
Second, if details of your stone are complicated, we need to choose soft hardness for you, as rubber can tightly fit every small corner of the master mold. In the contract, if details are easy, 30, 35 hardness is better.
2, About viscosity
Generally speaking, it depends on whether you have a vacuum chamber.
(1)If you do not have a vacuum chamber, we need to choose low viscosity for you, for bubbles can easily release, therefore will not influence the property, what’s more, not
destroy the design.
(2)If you have a vacuum chamber, viscosity is not a problem.

Using Guidance.
(1) Take out a certain amount of liquid silicone base (part A)from the container;
(2). Take out a certain amount of liquid silicone base (part B) from the container and mix with part A.
(3). The two components of silicone rubber must be mixed homogeneously, otherwise, it will be partly cured and solidified;
(4). Deaerate in a vacuum cupboard to achieve bubble free vulcanization;
Note: If no vacuum de-airing equipment is available, air entrapment can be minimized by mixing a small quantity of A and B component, then using a brush, painting the original with a 1-2mm layer. Leave at room temperature until the surface is bubble free and the layer has begun to cure. Mix a further quantity of base and curing agent and proceed as follows to produce a final mold.
(5). Pouring the deaerated mixture over the highest point of the model to form casting mould;
(6). Demolding after the liquid silicone solidified thoroughly.
(7). The mixed liquid silicone rubber will solidified in 3-4 hours under room temperature.
