A Better Tin Cure Choice for Molds That Need Easier Release
When your mold has deeper undercuts, finer detail, or shapes that are harder to peel off cleanly, a softer tin cure silicone can make demolding easier and more forgiving.

WHY THIS PAGE EXISTS
Not every mold should start with a firmer grade.
If your part has delicate edges, deeper undercuts, or shapes that are more difficult to remove cleanly, a softer silicone can help the mold release with less stress during demolding.
That often means fewer damaged edges, more practical mold handling, and a better first trial for detailed designs.
Soft Tin Cure Silicone Rubber for Easy Demolding of Small Detailed Molds
| Section | Details | Remark |
|---|---|---|
| Best for | Candle molds , Soap molds ,Craft molds Small decorative resin molds Fine ornamental reproduction Detailed molds with undercuts | Soft silicone helps easier demolding when the casting has fine details, fragile patterns or complex shapes. |
| Not recommended for | Large molds, heavy castings, thin-wall molds that need strong shape support, or applications where dimensional stability is more important than easy release. | For large or heavy molds, a higher Shore A grade with better shape support is usually recommended. |
| Typical Shore A | Shore A 5 / 10 / 15 /20 | Shore A 5–15 is usually better for easier demolding; Shore A 20 is better when more shape support is needed. |
| Viscosity | 5000/8000/11000 mPa.s | Lower viscosity is better for pouring fine details; higher viscosity can be selected when more body or less flow is required. |
| Mix ratio | Standard 100:3 | Catalyst ratio can be adjusted according to required pot life and curing speed. |
| Pot life | 10 min / 20 min / 30 min /40min/ 1-2h adjustable | Adjustable according to application and working temperature. |
| Cure time | 2h / 4h / 6h / 8h/12h/ 24h / adjustable | Faster or slower curing systems can be selected for different production needs. |
| Cure system | Tin cure | Also known as condensation cure RTV-2 silicone rubber. |
| Sample suggestion | TC-05/ TC-10/ TC-15/TC-20 | depending on mold size, pattern complexity and demolding difficulty. |

Best when maximum softness and flexible release matter most.
A practical soft-grade option for easier demolding and better daily handling.
A softer choice with slightly more body for buyers who still want easier release.
We can recommend the right starting grade based on your mold size, shape complexity, and casting material.
A softer mold usually releases more naturally from more complex shapes.
Helpful when the mold design includes detail that is easy to pull or damage.
A softer body can work better where the mold needs to stretch slightly during release.
Often more practical for candles, soaps, crafts, and decorative resin parts.
APPLICATIONS
These applications demand high detail, flexibility, and reliable demolding performance. Proper silicone selection ensures consistent results and longer mold life.
WHEN THIS IS NOT YOUR FIRST CHOICE
This page may not be the best starting point if your mold is:
Often yes. A softer mold usually releases more easily from shapes that need more flexibility during demolding.
Not necessarily. Easier release helps some designs, but mold life also depends on wall thickness, handling, and casting conditions.
Usually not the best first choice. Larger molds often need more support.
