Method of Application

    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.

 

Attention:

1. There are 30 minutes of operation time (at room temperature) when adding 2% curing agent, and the mold can be completely cured in 4 hours. Generally, the mold is better placed for 24 hours before use. At this time, the performance of the mold is relatively stable in all aspects, and the use effect will be better.

2. The mixing ratio of silicone and curing agent is  100:2-3.  For example,  100 grams of silicone, add 2-3 grams of curing agent. In principle, do not take the method of adding less or more curing agents.

 

Shelf Life:

12 months at room temperature (under 25C) without opening.

 

Packing:

25Kg / 200Kg

*Iron bucket packaging.

Sealed storage away from heat, light, and water to prevent deterioration. This product is shipped as non-hazardous.
