What is the ratio of dual component silicone to curing agent

Hits: 280 img

We all know that two-component silicone is composed of silicone and curing agent. To cure silicone, a certain proportion of curing agent must be added. So what is the correct ratio of liquid silicone to curing agent? According to the type of two-component liquid silicone, it can be divided into additive liquid silicone and condensed liquid silicone, and the ratio of different types of silicone is also different.

1、 The ratio of condensed silicone to curing agent is as follows:

1. The dosage of curing agent is 1.5%, and the gel is still flowing after 2.5 hours. It can be demolded after 10-12 hours.
2. The amount of curing agent added is 2%, and it will still flow in 20-30 minutes. It can be demolded in 2-3 hours.
3. The amount of curing agent added is 3%, and the colloid is still flowing after 28-30 minutes. It can be demolded after 1.5-2 hours.
4. The amount of curing agent added is 4%, and the colloid is still flowing for 10-15 minutes. It can be demolded within 1-1.5 hours.

2、 The ratio of added silicone to curing agent is as follows:

1. Semi transparent silicone, with a 1:1 weight ratio of silicone to curing agent.
2. Highly transparent silicone, with a weight ratio of 10:1 between silicone and curing agent.
