What are the usage methods and precautions of silicone ink?

Silicone ink is used when we make silicone molds. Generally, methyl silicone oil is used. Methyl silicone oil is colorless, odorless, and not volatile; it is insoluble in water, methanol, and ethylene glycol, and can be mixed with benzene and dimethyl ether. , methyl ethyl ketone, carbon tetrachloride or kerosene are miscible, have a small vapor pressure, high flash point and ignition point. What do we need to pay attention to during use? The following Hongtu Silicone will teach you the precautions for using silicone ink.

1. How to use silicone ink

   1. Add sulfur to the material twice (150°C/1-2 hours), and clean the surface.

   2. After taking out the silicone ink from the refrigerator, you need to wait for the temperature of the silicone ink to return to normal temperature or close to normal temperature before using it. During use, if the viscosity is found to be too high, you can properly add odorless kerosene to adjust to an appropriate viscosity, and wait until the ink reaches room temperature and a suitable viscosity before performing screen printing, pad printing or spot printing.

   3. Vulcanize after standing for 5-10 minutes in a dust-free environment.

   4. Bake at 180-250°C for 10-15 minutes for vulcanization, and low-temperature printing silicone ink at 110-130°C for 20-30 minutes for vulcanization.

   2. Precautions for silicone ink

   1. After opening the can, the product should be fully stirred evenly.

   2. Printing needs to create a good and suitable environment. Hongtu Silicone warmly reminds that the best environment for printing is: the operation room needs to be dust-free, and the temperature is controlled below 25°C and the humidity is controlled at 55-75%; if the humidity is too high Low sensitivity will lead to static electricity in silicone ink, which will increase the number of defective printed products.

   3. The product to be printed should be subjected to secondary vulcanization at a temperature greater than 150°C/1-2 hours before use, otherwise it will cause poor local vulcanization of the paint film.

   4. Please keep the silicone ink refrigerated, and the unused silicone ink should be sealed and refrigerated.

   3. Shelf life of silicone ink

   The storage period of silicone ink is 3 months; if the product has passed the shelf life, it can still be used after passing the technical inspection.

4. Storage conditions of silicone ink

Airtight refrigeration;

   Storage temperature: 0-10°C, humidity: 55-85%; waterproof, leak-proof, sun-proof, high-temperature-proof, and away from fire sources.
