Descripción del producto

1. Description of liquid RTV*2 silicone rubber to make artificial stone molds

It is a kind of room temperature vulcanized silicone rubber in condensation type. It's generally named as two part silicone rubber, Part A is a flowable liquid, part B is the curing agent or catalyst. It's mainly used for all mold making with different size and pattern.

2. Characteristics of liquid RTV*2 silicone rubber to make artificial stone molds

(1). Suitable for both pouring molding and brushing molding

(2). Strong tear strength and tensile strength

(3). Easily release air to avoid bubbles

(4). excellent non-stick effect

(5). Various hardness from 5 to *0 shore A

(6). Excellent flexibility, easy to demould.

(7). High temperature resistance, high duplication times and repeated use

(8). Good cut-growth resistance

3. Application of liquid RTV*2 silicone rubber to make artificial stone molds

two component liquid silicone making mold for stone figures molding, which with good tensile strength as well as high duplication times ,so it is perfect for making mold in statue and figures industries ,such as Stone figurine ,ceramic statues,polyurethane statuary, ceramic statues,polyurethane animals,Buddha, plaster ceiling, artificial stone, GRC home decorations etc.while,it also application for making mold for Resin and poly resin crafts, Lighting ornaments, candles crafts, statue Buddha, relief, artifacts copied, Animals and plants sculpture.

5. Using instructions of liquid RTV*2 silicone rubber to make artificial stone molds

Step 1: prepare the original molds

Prepare an perfect mold modle and clean it totally(the release agent can be detergent, soapy water and Vaseline)before operation .Take **0g silicone material and 2~5g curing agent strictly and mix them evenly.

*Notes:Make sure the toys and operation tool cleaned up totally to avoid uncure problem .

Step 2: Vacuum pumping

Without exception, this step takes less than *0 minutes.(normally is 5munites) Otherwise, it will cause cross linking reaction, and no more further steps will be available

Step 3: Pouring casting or Brushing operation

1. For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air . (mold with fine and precision patterns with low hardness.)

2.For delicate pattern products we suggest use brushing operation way.which can copy the pattern exactly .brushing way require high viscosity which wont be easy to flow away and easy to brush(large size molds with high hardness)

3.The amount of the curing agent can be adjusted according to the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.but we dont suggest to add silicone oil avoid oil problem.

Step 4:Demoulding:

After *5 hours later, can demould the silicone mold, it's will be better for molf to demould after *4 hours.

Notes:The curing temperature and curing time can be adjustable according to the operation conditions.

Package

*5KG/drum vacuum packing for part A *1kg/ bottle catalyst for part B

**0KG/drum packing for part A *1kg/ bottle catalyst for part B

Shelf life and transportation

1. Twelve(*2) months when stored at *5â„ƒ in tightly closed original packages.

2. The liquid silicone rubber is non- dangerous product (not inflammable and explosive), which could be transported as general chemicals.

FAQ

1. Why will the silicone mold be reused only for a few times?

It can be due to the following reasons:

a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which can destroy the molecular weight of silicone rubber and reduce the tension and tear strength.

b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs or the silicon rubber with a low hardness to makes molds for large sized products with simple designs.

(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)

2. Why does the silicone mold appear to dry outside but wet inside?

Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.

Solution: Add 0.1% water into the silicon rubber and Stir over a low speed briefly when you use it.

3. Why is the silicon mold oily?

The molding silicone rubber itself doesnt contain any oil, so it wont be oily. If the mold is oily, it may be because you add the compound silicone oil( the compound of silicon oil and white oil). The white oil is not silicon oil but a kind of petrochemicals.
