silicone rubber for garden stone & sculpture molds making

 RTV silicone rubber 

Description of RTV silicone rubber:

HY-638# silicon rubber is mainly used for toy gifts and craftwork gifts with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. It is suitable for small products or fine and precision products which is difficult to demould. This silicone rubber is one of the products with the highest use level in the production of craftwork gifts and the shrinkage is up to 2.

Applications of RTV silicone rubber:

Poly technique, lightings, candles, and  molds in multiple pieces for large products.

Standard Datasheet:

General Description of RTV silicone rubber:

RTV-2 molding silicon rubber and silicone rubber are general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes,and in 2-3 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion. The silicone rubber is mainly applicable to mold duplication of poly crafts, resin craftworks, lightings, candles, etc. and fabrication of precision molds.

Operation Instruction for RTV silicone rubber:

The product is white or red flowing liquid with general hardness of 2250A°after curing . If the customer wants to make large products and large size molds, the mold should be made of silicone rubber with high hardness. On the contrary, if  the mold with fine and precision patterns , it should be made of silicon with low hardness. The amount of the curing agent depends on 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.

(Note: our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)

The proportions and reactions of the curing agent and the silicon are listed as follows:

1. Adding curing agent 1%, the silicone can still be operated within 2.5 hours and can be demoulded after 6-8 hours.

2. Adding curing agent 2%, the silicone can still be operated within 50 minutes to 1 hour and can be demoulded after 2-3 hours.

3. Adding curing agent 3%, the silicone can still be operated within 28 - 30 minutes and can be demoulded after 1.5-2 hours.

4. Adding curing agent 4%, the silicone can still be operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.

 RTV-2 silicone rubber for electronic potting compound

Brief Introduction of Electronic potting compound silicone rubber
Electronic potting compound silicone rubber is a code of addition cure silicone rubber, which is similar to KCC potting silicone rubber. It has a low viscosity and mixing ratio 1:1, easy in operation and pourable. The electronic potting compound silicone rubber is suitable for bonded seal of electronic components, power module and control module, which requires waterproof and anti-vibration.

Applications of Electronic potting compound silicone rubber
The potting silicone rubber is a kind of low viscosity, Inherent flame resistance, two components silicone rubber with heat-conducting. It can cure in both room temperature and heated temperature. It has the feature of the higher temperature the faster of the curing time. It can be applied to electronic components for insulation, waterproofing, fixed and flame retardant. The flame retardant UL94-V0 level can be achieved. It mainly applied in electronic components surface with materials of PC (Poly-carbonate),PP,ABS,PVC, etc. and metal materials.

Operation of Electronic potting compound silicone rubber
1.    Put part A and part B in separate container with equal dosage and stir evenly when mixing the two parts together.
2.    Put the mixture into the vacuum machine under 0.08 MPa for 5 minutes.
3.    The temperature influences the curing time of electronic potting silicone rubber. When in too low temperature, we suggest customers appropriately heat the mixture to accelerate vulcanization.

Storage of Electronic potting compound silicone rubber
Electronic potting silicone rubber is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about 12 months from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
