Description:
HY630 is liquid rubber(condensation cure rtv, or tin cure silicone) mainly used for silicone plastic molds, with the advantages of good tensile strength, high tear strength, high temperature resistance, excellent chemical resistance, high duplication times, long-term stability, high durability, etc. This moulding rubber is one of the products with the highest use level in the production of craftwork gifts and its shrinkage is even lower than 2‰. RTV mould rubber and silicone rubber are general called two-component room temperature vulcanization silicone with excellent fluidity and good operational flexibility, easy moulding process, and so on. Add curing agent of 2%-3% at the room temperature, the rtv mould rubber is still operational within 30 minutes,and after 2-5 hours, the silicone elastomer(silicone mold) will be obtained with resistance to deformation, extremely high or low temperature, acid and alkali and expansion. The rtv mould rubber is mainly applicable to mold duplication of poly crafts, resin craftworks, lightings, candles. It is also suitable for fabrication of precision molds.
RTV Mould Rubber Applications:
Plastic molds, silicone soft plastic molds,making molds for plastic toys, plastic crafts, plastic gifts, PU products,stationary products, pavement, and so on. It has a quite broad applications due to its favorable viscosity and hardness.

Operation Instruction for rtv mould rubber:
The product is a kind of white flowing liquid . If the customer wants to make large products and large size molds, the mold should be made of rtv mould rubber with high hardness. On the contrary, if the mold with fine and precision patterns , it should be made of rtv mould rubber with low hardness. The amount of the curing agent depends on the actual requirements of the customer.
The proportions and reactions of the curing agent and the silicone are listed in the following:
1. Curing agent 1% added, the silicone can still be operated within 2.5 hours and can be demoulded after 6-8 hours.
2. Curing agent 2% added, the silicone can still be operated within 50 minutes to 1 hour and can be demoulded after 2-3 hours.
3. Curing agent 3% added, the silicone can still be operated within 28 – 30 minutes and can be demoulded after 1.5-2 hours.
4. Curing agent 4% added, the silicone can still be operated within 10 – 15 minutes and can be demoulded after 1 -1.5 hours.
The manufacturer of liquid silicone rubber for more than 10 years.
