Knowledge about screen printing silicone ink

1. Basic Knowledge:
The ratio of printing silicone ink to Catalyst agent is 100:2.
The curing time of Silicone is related to temperature and air humidity. Under normal temperature, when you add curing agent and bake at 120 °c, the drying time is 6-10 seconds. The Operating Time of Silica Gel on the screen is more than 24 hours, and the temperature rises, curing speeds up, the temperature drops, curing slows down. When you add hardener, please seal low temperature preservation, can increase its operating time.
The amount of diluent added is generally 5%-30%, according to the needs of the printer to add, the more the relative drying speed will slow down, the defoaming ability will become stronger,Liquidity will be better.

2. Storage:
Printing silicone ink: sealed storage at room temperature;Catalyst agent:
Catalyst agent if stored for too long, it is easy to layer, when used to shake well.
Silica Gel curing agent is a transparent paste, can be stored for a long time, more than half a year to seal better. The Silica Gel which has been mixed with hardener should be stored in the refrigerator below 0℃. It should be used within 48 hours. When using it, the new slurry should be added and mixed evenly.

3. The different fastness type Silicone ink and the bonding agent, may solve each kind of cloth fastness question.
4. Universal anti-poisoning agent, can solve the problem of fabric poisoning, and can be on the machine, will not cause waste.
