We all know that two-component silica gel is composed of silicone and curing agent, to make silicone gel curing must be added a certain proportion of curing agent, so how much is the correct proportion of liquid silicone and curing agent, according to the type of two-component liquid silicone, divided into molding liquid silicone and condensed liquid silicone, different types of silica gel its ratio is not the same.

The proportion of condensed silica gel and curing agent is as follows:
1, the curing agent added 1.5%, 2.5 hours colloidal flow, 10-12 hours can be demoulded.
2, curing agent add 2%, 20-30 minutes will flow, 2 ~ 3 hours can be demoulded.
3, curing agent add 3%, 28 ~ 30 minutes colloidal flow, 1.5 ~ 2 hours can be demoulded.
4, curing agent add 4%, 10 ~ 15 minutes colloidal flow, 1 ~ 1.5 hours can be demoulded.

Molding silica gel and curing agent ratio is as follows:
1, translucent silicone, silicone and curing agent ratio of 1:1 weight ratio.
2, high transparent silicone, silicone and curing agent ratio of 10:1 weight ratio.
