Features of Silicone rubber for concrete stone replication:

Silicone rubber for GRC products replication has good characteristics of easy operation, light viscosity and good flowability, low shrinkage, favorable tension, No-deformation favorable hardness and high temperature, acid alkali and ageing resistance.

Basic description of Silicone rubber for concrete stone replication:

Silicone rubber for GRC products replication is a kind of silicon consisted with two part, one is silicon another one is catalyst, the ratio is 100:2 under temperature 25°the operating time of mold making silicon is half an hour,demould time 2-4 hours. if customers make molds in brushing way,628 and 638 are good choices as they have moderate viscosity.

 Guideline of Silicone rubber for GRC products replication: 

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.

FAQ for Silicone rubber for concrete stone replication:

What’s the solutions for the sticky of the silicone mold?

The main reason for this problem is that you do not handle the products or original molds well, then you should deal with the original mold or products carefully before molding. Such as for the products with a complicated

pattern or a unsmoothed surface, you should polish and clean the products after which it will be molded ,then spray the release agent. Normally, the release agent can be Vaseline , detergent. liquid wax Etc. In practical process, you can bush different release agent according to different material.

The second reason is that the operator pour the silicone into the mold when the mixture is mixed evenly, then the finish silicone mold will not cure and dry entirely..
