Liquid silicone rubber compound for plaster products moulding

1.Applications of mould making silicone rubber:
Mould making silicone rubber is suitable for industries such as toys, gifts, furniture decoration, construction decoration, human replica,  stationeries, resin crafts, unsaturated resin crafts, poly resin crafts, candle crafts, plastic crafts, plaster crafts, artificial plant and animal crafts ,Buddhist statue crafts.

2. Description of mould making silicone rubber:
Mould making silicone rubber is a flowable liquid, and the quality has nothing to do with the color. It consists of two parts. Part A is a flowable liquid silicone rubber, part B is the curing agent. Dealing with the original model by polish the surface and print release agent first, take some liquid silicone rubber , add 2%-3% curing agent of the amount of silicone, and mix them evenly. Then after vacuum-pumping the mixture, you can pour it into the mould frame. The silicone mould will be cured in 2-3 hours and after 24 hours you can put it into production.

Note: The time for vacuum-pumping should be less than 3-5 mins ,otherwise, once the silicone rubber has cross-link reaction during vacuumizing, and no more further steps will be available.

3.Features of mould making silicone rubber:

a) Good characteristics of easy-operation

b) Good flowability and light viscosity

c) Low shrinkage

d) No deformation

e) Favorable tension

f) Favorable hardness

g) High temperature resistance, acid and alkali-resistance and ageing resistance

5.  RTV Silicone for Gypsum  Mold Making  frequently asked question:

 Why does the RTV Silicone molds appeared striately and unsmoothly?

It is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation. So when you make silicon molds, firstly you should polish the product, spray the mold spray evenly on the product. In this case, the problem can be avoided.
