Silicone Rubber for Artificial Stone Mold

Silicone rubber for artificial stone mold

Applications
Artificial stone, such as reef stone, antique brick, weathered brick and timber lines stone, is generally made of cement, resin, gypsum and so on. Using for wall decoration, floor decoration, it is beautiful and with good quality.

Our silicone rubber, especially addition cure (platinum catalyst) is perfectly using in making artificial stone mold, it owns property of high heat resistance— 500 centigrade, less demolding time, more reproduction times and most important: Less shrinkage. Shrinkage for condensation cure is 0.2%-0.5%, for addition cure, it's less than 0.1%, which can make precise designs.

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.
3, About Color
(1) We can produce the simple pure color, such as red, blue, green, yellow and so on.
(2) We can also produce your needing complicated color, such as silver, gold color, but need your palette.

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.
