Introduction of high transparent mold silicone:

Highly transparent mold silicone is a kind of two-component addition molding silicone, but its transparency is quite high. The same product has the advantages of high transparency  good mold release. It can be seen whether the casting material in the mold has defects such as bubbles.

High transparent mold silicone use:

It is used in the production of diamond molds such as imitation zircon, imitation gemstones, resin diamonds, crystal face drills, simulation drills, etc. It can also be used for model manufacturing of precision automobiles, models, mechanical parts, nail (nail small jewelry) molds, etc.,  can also be applied Manufacturing of mold making in furniture industry  electronics industry.

Features of high transparent mold silicone:

1. This product is a two-component addition molding liquid silicone rubber, the ratio is 1:1

2. It is  limited by the thickness of the product  can be deeply cured

3. Has excellent high temperature resistance, the temperature can reach 300-500 degrees

4. Food grade, non-toxic  tasteless, passed FDA food grade certification

5. High tensile  tear resistance, many times of mold turning

6. It can be heated  cured, easy to form,  easy to operate

High transparent mold silicone operation process:

1. Mixing: A component (base rubber)  B component (curing agent) are mixed at a weight ratio of 1:1. The mixing can be done manually  with equipment. 　　

2. Defoaming: The mixed rubber should be defoamed before filling. When used in a small amount, it can be carried out in a vacuum dryer. Under vacuum, the volume of the rubber will foam  increase by 4 to 5 times. Therefore, the volume of the degassing container should be 4 to 5 times larger than the volume of the rubber. After a few minutes The volume of the glue returns to normal,  the defoaming process is completed when no bubbles escape on the surface (about 10 minutes). 　

3. Surface treatment: the surface of the mold  the surface of the material that needs to be potted should be cleaned  then liquid paraffin should be used as a release agent.

4. Vulcanization  demoulding: the compound after mixing  deaeration is cured at 120±5℃ for 30 minutes, 60～70℃ for 2～3 hours, curing time at room temperature is 24 hours, curing temperature  time can be based on Depending on process conditions.

Packing, storage  precautions:

1. The base glue of this product is packaged in 40kg/group  400kg/group.

2. This product is non-hazardous  should be sealed  stored in a cool place to prevent rain  sunlight.

3. The storage period of this product is half a year. If the viscosity increases during storage, its fluidity can be restored under the action of shearing force (stirring). It is recommended to put the rubber compound in the container  mix it first,  then add the curing agent to mix. It can still be used after the overdue re-inspection is qualified.

4. Avoid contact with condensed silicone rubber vulcanizing agent during operation. Amines, sulfur, phosphorus  other chemicals may cause the rubber to  vulcanize.
