Introduction of sandstone mold silicone rubber :

Sandstone mold silicone, sandstone handicraft silicone, sandstone sculpture mold special silicone is usually a kind of two-component room temperature vulcanized silicone rubber , A component is a fluid liquid glue, B component is a curing agent (vulcanizing agent), the two Rapid prototyping after mixing. Hongye's condensation-type silicone and addition-type silicone are both suitable for sandstone carving molds.

Sandstone mold silicone rubber application:

Sandstone mold silicone rubber is suitable for making silicone molds for the following products: sand sculpture sandstone artwork, garden decoration, outdoor sculpture, villa indoor and outdoor decoration, hotels, large urban garden sculptures. Especially for overmolded cultural stone, sand sculpture sandstone artwork, artificial sandstone material, handicraft ornaments, garden sculpture, relief mural, simulation animal sculpture, Roman column, sandstone flower pot, sandstone line, sandstone lighting, art wall tiles The production of silicone molds for sandstone art products such as boards and artists.

Sandstone mold silicone rubber performance characteristics :
1. It is a mold glue especially for cultural stones, sand sculpture sandstone artworks, and large-scale urban garden sculptures. It has good elasticity, high tear strength and good replication effect;

2. The silicone mold made is not easy to be deformed, resistant to high temperature, acid and alkali, and does not expand;

3. Good weather resistance, many times of overturning, and low linear shrinkage;

4. Good tensile force, good elasticity, high tear strength and long service life;

5. The curing speed at room temperature, the hardness of silica gel, and the fluidity of liquid glue can be specially adjusted and produced according to the customer's product requirements, and the silica gel can be customized for you;

6. It has better hydrolysis resistance, and is more suitable for making sandstone carving molds of various sizes and complex patterns and shapes, as well as large gypsum, sandstone cement, stone and other molds.

Description of the mold opening method and operation process of sandstone relief mold glue material :

There are three ways to open the sandstone embossed silicone mold: overmolding, rinsing, and perfusion.

If the split mold is opened, it is recommended to use the mold silicone rubber with high hardness as the mold ; on the contrary, if the injection mold is to be used, it is recommended to use the soft mold silicone rubber for the mold.

(Note: The company's products do not recommend adding silicone oil, special soft silicone molds or complex patterns and precision small, you can add 5%-10% silicone oil to adjust the softness of the silicone mold for demoulding.)

Hongye silicone - mold silicone rubber HY -640 performance parameters:

Remarks : The above parameters are only the parameters of this model HY-640, the parameters of other models are not shown; if you have special needs, please contact our company; after curing, the hardness, viscosity, and operating time can be specially adjusted and provided according to customer needs.

Reference for the addition ratio of condensation type silica gel curing agent :

The amount of curing agent added can be determined according to the actual requirements of customers. If fast drying and rapid mold release are required, more curing agent should be added accordingly; on the contrary, if slower mold release is required, less curing agent should be added (but the curing agent is added amount cannot exceed 5%). The specific reference is as follows:

1. When the amount of curing agent is 1%, the colloid will still flow in 2.5 hours, and it can be demolded in 6-8 hours.

2. When the amount of curing agent is 2%, the colloid will still flow in 50 minutes to 1 hour, and it can be demolded in 2 to 3 hours.

3. When the amount of curing agent is 3%, the colloid will still flow in 28-30 minutes, and it can be demolded in 1.5-2 hours.

4. When the amount of curing agent is 4%, the colloid will flow in 10-15 minutes, and it can be demolded in 1-1.5 hours.

Precautions for the use of sandstone mold silicone rubber and sculpture mold silicone rubber :

1. The amount of curing agent should be determined according to the temperature, and it should be reduced if the temperature is high. If the curing agent is used too much, the mold will become hard and brittle; if the curing agent is used too little, the operation time will be prolonged.

2. In order for your mold to achieve the best use effect, please store the mold for at least 24 hours before use.
