Usage of molding silicone rubber :

For the duplication and mold making of glass crafts,lighting,candle ,culture relics duplications.

Description of silicone rubber for resin&unsaturated resin cratfs  :

Liquid silicone for molds(pourable silicone\soap mould silicone \resin & undaturated resin cratfs) 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 demuould.this liquid silicone for molds(pourable silicone /soap mould silicone) is one of the products with the highest use level in the production of craftwork gifts and the shrinkage is up to 2%.

Operation instruction for silicone rubber for resin&unsaturated resin crafts:

the product is white or red flowing liquid with general hardness of 34-38 shore A after curing,if the customer wants to make large products and large size molds.the mold should be make of silicone rubber with high haardness,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 os 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 silicone 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 proprtions and reactions of the curing agent and the silicone 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 minuted 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.
