Feature of Tin Cure Silicone Rubber

MethodofApplication:

1. After shaking the curing agent (Part B), weigh the material according to the ratio of A: B = 100:2 and mix and stir evenly. The bottom and the walls of the container must be well scraped to ensure that the silicone and curing agent are fully mixed here. It must be stirred evenly. If not, it will affect the service life of the silicone mold.

2.  Degas the well-mixed rubber under a vacuum, the vacuuming time should not be too long, generally not more than 10 minutes.

3.  The mold can be fully cured after 4 hours at room temperature. Do not heat to cure. Even if you want to heat it up to accelerate its curing time, the temperature is not recommended to be higher than 100 °C. For best results, molds are best left for 24 hours before use.
