We all know that two-component silicone rubber is composed of silicone and curing agent. To cure silicone rubber, a certain proportion of curing agent must be added. So what is the correct ratio of liquid silicone rubber to curing agent? According to two-component liquid silicone The types of rubber are divided into addition liquid silicone rubber and condensation liquid silicone rubber. The proportions of different types of silicone rubber are also different.

1. The ratio of condensation silicone rubber to curing agent is as follows:

1. Add 1.5% curing agent, the colloid will still flow in 2.5 hours, and can be demoulded in 10-12 hours.

2. Add 2% of curing agent, and it will still flow in 20-30 minutes, and can be demoulded in 2-3 hours.

3. Add 3% curing agent, the colloid will still flow in 28 to 30 minutes, and can be demoulded in 1.5 to 2 hours.

4. Add 4% curing agent, the colloid will still flow in 10 to 15 minutes, and can be demoulded in 1 to 1.5 hours.

2. The ratio of addition silicone rubber to curing agent is as follows:

1. Translucent silicone rubber, the ratio of silicone rubber to curing agent is 1:1 by weight.

2. Highly transparent silicone rubber, the ratio of silicone rubber to curing agent is 10:1 by weight.
