[新聞爆掛] How to adjust the solidification time of mold silicone?

[複製網址]
Mold silicone is a general term for various types of silicone. Commonly used are industrial grade silica gel (condensation type) and food grade silica gel (addition type). Due to the advantages of high reproduction accuracy, convenient operation and high production efficiency,Silicone molding products,         it is recognized and used by the general public.

Industrial grade silica gel (condensation type): the ratio of curing agent is 100:2-3, such as 100 grams of silica gel, add 2-3% curing agent and stir evenly. Typically used for perfusion molds.

Food grade silica gel (additive type): silica gel is two-component AB type. Agent A is silica gel and agent B is curing agent. They are mixed in a 1:1 ratio. Due to its strong fluidity, it is suitable for casting molds. For example, the operating time is 30-40 minutes, and the curing time is about 3-4 hours at room temperature of 25°C. It can also be rapidly cured by heating, for example, heating at 120°C for about 20 minutes.
