Frequently asked questions of RTV-2 silicone rubber for plaster crafts and cements
Why does the silicone mold get burnt out?
This consequence happens only because you have left out the important notes when using unsaturated resin materials to produce your products. The unsaturated resin produces great heat when added the curing agent. So you must demould the product within 3 minutes to avoid this problem.
Need the datasheet and the price of Molding silicon for reference, please feel free to confirm some of your information in advance,
1) What's the material of your products, plaster, resin, cement, wax, or any others, please?
2) What is the size of your products, small(within 30cm), medium(30-60cm) or big(60-200cm), please?
3) How about your way of making silicone mold, by pouring way or brushing way, please?
Getting your information in details, we will recommend the most suitable Molding silicon with the best price at the first time for your reference.
(Note:we do not recommend silicon oil. For special soft mold or molds with complex pattern or fine details, 5%-10% silicon oil can be added to condition the flexibility of the mold for convenience of release)
Curing agent and silicon proportion and reaction(in temperature 25ºC):
1,Added with 2% of curing agent, silicon can still flow within 2.5 hours, mold can be released in 7-8 hours.
2,Added with 3% of curing agent, silicon can still flow within 100mins to 1 hours, mold can be released in 6-7 hours.
3,Added with 4% of curing agent, silicon can still flow within 60-70 minutes, mold can be released in 5-6 hours.
4,Added with 5% of curing agent, silicon can still flow wtithin 50 minutes, mold can be released in 4-5 hours.
