How to use
- Arrange the adjustable mold housing around a clean, securely fixed master and fasten the walls with binder clips.
- Stir Parts A and B separately before weighing.
- Measure equal weights of Parts A and B, then mix slowly and thoroughly.
- Pour the mixed silicone into the prepared housing within the typical working time.
- Allow the silicone to cure fully before removing the housing and demolding.
Vacuum degassing is recommended for deep cavities, fine detail or demanding surface-finish requirements.
Typical applications
Suitable for mold development for resin, wax, gypsum, plaster, concrete, soap, decorative objects, prototypes and similar casting projects. Suitability depends on the master material, release system, geometry and production conditions.
Cure inhibition
Platinum-cure silicone can be inhibited by sulphur-containing clay, latex gloves, tin-cure silicone residue, amines, some epoxy curing agents and uncured or unsealed SLA, LCD or DLP resin prints. Keep tools and master surfaces clean and run a small test cure before production.
Storage and shelf life
Store unopened original containers at 15–25°C. Recommended shelf life is 12 months from the date of manufacture.
