Silicone - Defiant 15

Siraya Tech | 3D Printing UV Resin | Platinum Silicone | NFEP Film

All new Defiant 15 from Siraya Tech with extra resistance to platinum poisoning without complicated post-processing is perfect for your next project. With just 30 minutes of curing the part submerged in water, Defiant 25 will cure without the part being clear coated.

Has good resistance to silicone poisoning, especially due to UV resin. Siraya Tech Defiant 15 requires a lot less post-processing to make mold cure properly.

Platinum silicone poisoning presents a unique challenge, as it arises not only from 3D printing resins but also from the silicone manufacturing process itself. To achieve the best possible results, it's crucial to identify the ideal combination of silicone and resins. Defiant 15 has been engineered to exhibit greater tolerance compared to traditional platinum silicone; however, certain resins inherently offer better compatibility with silicone and necessitate less post-processing.

Resin Selection and Post-Processing: Essential for 3D UV Resin Prints.

Ideal with 3D Printing UV Resin

Defiant 15 liquid silicone has extra resistance to curing inhibition, No coating is needed. It works best with our Fast, Build, Blu, Easy and Sculpt resins.

Tear Resistant & Longevity

Compared with others, Defiant 15 has better flexibility and stronger tear resistance, and silicone rubber has a longer life span and can be reused many times.

Thinner Viscosity

This clear silicone mold making is easy to pour and degas, and it's thinner, making it perfect for beginners.

How to use Silicone Defiant 15

1. Mixing A part and B part

Mix Siraya Tech Defiant 15 clear platinum mold making silicone rubber part A and part B in 1:1 by weight (or volume)

2. Stir well

Then stir the silicone mold making rubber for 5 minutes. Make sure to stir the liquid rubber mixture well for better results.

3. Poring into the mold frame

Pour the fully stirred mold making silicone into the film frame, pot life is about 15 minutes and fully cures in 4 - 6 hours (ambient temperature at 25C)

4. Demoulding

Siraya Tech liquid silicone rubber is very easy to release from molds and the resulting molds are very flexible. Even beginners can make their own molds very easily.
