Proper storage and use of silicone screen printing ink ensures its quality and performance and extends its service life. Here are some suggestions for storing and using silicone screen printing ink:
Storage:
Environmental Selection: Silicone screen printing ink should be stored in a cool, dry, well-ventilated place, away from direct sunlight and high temperature environments. The optimal storage temperature is 0℃~24℃, and the humidity is controlled between 55%~75%. This can prevent the ink from deteriorating or generating static electricity, which will lead to an increase in the rate of poor printing appearance.
Container selection: Ink should be stored in airtight containers to prevent moisture and impurities from entering. Inks that are not used for a long time are recommended to be stored in a sealed state, with the temperature controlled at 0~10℃ and the humidity maintained between 55%~85%.
Waterproof and leakproof: During storage, pay attention to waterproofing, leakproofing, sun protection, high temperature protection and keeping away from fire sources to ensure the safety and quality of the ink.
use:
Preparation: Before use, make sure the printing machine and silicone printing screen are in good condition. The mesh of the screen should be selected appropriately. Generally, the mesh should be around 80~120 to ensure that the silicone can smoothly adhere to the substrate through the screen.
Ink stirring: Since silicone screen printing ink may separate after being placed in the container, it is best to stir it evenly before use to ensure the consistency of the printing effect.
Cleaning: Before printing, the release agent and oil stains on the surface of silicone rubber products must be cleaned with clean water or odorless kerosene. This helps ensure that the ink adheres evenly, improving print quality.
Baking and Curing: Depending on the type of silicone ink used, baking may be required. For inks that need to be baked, the baking temperature is generally between 120~180℃, and the baking time depends on the specific situation, usually 10~15 minutes. After baking, the ink can be completely solidified without falling off. If the ink cannot be completely cured after baking, the oven temperature can be increased appropriately and the baking time can be extended.
