Usage of Silicon rubber for crafts mold making

Silicon rubber for plaster products is suitable for the mold making of large size products making in multiple pieces, reliefs, arts & crafts.

Description of  Silicon rubber for  crafts mold making

Silicon rubber for  crafts mold making 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 brushing silicon 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 Silicon rubber for  crafts mold making

Silicon rubber for  crafts mold makingwhite or red flowing liquid with general hardness of 23—27A°after curing . If the customer wants to make large products and large size molds, the mold should be made of silicon 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% silicon oil can be added to soften the mold for easy demould.)

The proportions and reactions of the  Silicon rubber for  crafts mold making  is listed as follows:

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

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

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

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