Silicone Catalyst F23 Clear
Add 5% of catalyst by weight to silicone rubber base. Please use a precise electronic scale to weigh the rubber and catalyst.
Mixing proportions and temperature:
- Below 0°C regardless of how much catalyst is added, the rubber will react very slowly, and never fully cure.
- Below 5°C the rubber will react very slowly and cannot be cured within 24 hours.
- Below 15°C the working time is approx. 30-60 minutes, with a curing time of about 12-24 hours.
- Temperatures about 25°C, the working time is about 15-30 minutes, with a curing time of about 4-6 hours.
- Temperatures about 35-40°C , the working time is about 10-15 minutes, with a curing time of about 2-3 hours.
