RTV-2 silicone rubber for gypsum statues
mold making​
Description:
HY-635#
plaster cast silicone is mainly used for plaster products molds
with the advantages of high tear strength, high durability, high
temperature resistance, long shelf life, high duplication times
etc. It is suitable for small products or fine and precision
products which is difficult to demould. This plaster molding
silicone is one of the products with the highest use level in the
production of many kinds of products, and the shrinkage is
even lower than 2‰.The
rtv mold making silicone rubber(condensation curing) is generally
called two-component room temperature vulcanization type with
excellent fluidity and operational performance. Add curing agent of
2%-3% at room temperature, the plaster molding silicone is still
operational within 30 minutes,and in 2-5 hours, a high tear
silicone elastomers will be obtained with resistance to
deformation, high-temperature, acid and alkali, and
expansion.
Applications:
This high
tear strentgh silicone rubber can be used in making molds for
plaster, polyurethane
, lighting ornaments, model design, stationery gifts,
artifacts replia, PU crafts, and so on.

Operation Instruction for rtv-2 plaster moulding material :
　　Our product, a flowing liquid with general hardness of 34—38A°after curing process, is in white color. also you can add some dye according to your needs, but you should contact with us first, because some type of dye will affect the silicone property and quality. If 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 silicone with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If requires faster drying rate, more curing agent should be needed; contrarily, if requires slower drying, less curing agent is needed. If all the operation is correct, you will obtain a perfect silicone elastomers for molding. The operation is not difficult, our salesmen can give tailored molding scheme for customers.(every salesmen of Hong ye company is well trained to provide with related technical consultation)
The proportions and reactions of the curing agent and the silicone are listed as follows:
　　1. Adding curing agent 1%, the silicone could still be operated within 2.5 hours, and could be demoulded after 6-8 hours.
　　2. Adding curing agent 2%, the silicone could still be operated within 50 minutes to 1 hour and could be demoulded after 2-3 hours.
　　3. Adding curing agent 3%, the silicone could still be operated within 28 - 30 minutes and could be demoulded after 1.5-2 hours.
　　4. Adding curing agent 4%, the silicone could
still be operated within 10 - 15 minutes and could be
demoulded after 1 -1.5 hours.
