The middle layer of screen printing silicone has the following characteristics:
1. Strong adhesion:
• As the middle transition part of screen printing silicone, it can firmly bond the bottom layer and the surface layer of silicone together, ensuring the stability and integrity of the entire screen printing silicone structure, and avoiding problems such as delamination and falling off. For example, after screen printing silicone on textiles, leather and other materials, the strong adhesion of the middle layer can ensure that the silicone pattern adheres to the surface of the material for a long time and withstands the test of friction, washing and other tests in daily use.
2. Good leveling:
• It has good leveling and can be evenly distributed between the bottom layer and the surface layer of silicone during the printing process to form a flat and smooth transition layer. This makes the pattern of screen printing silicone more beautiful, delicate and comfortable to the touch. If the leveling is not good, the middle layer may be uneven in thickness, affecting the overall quality and appearance of the screen printing silicone.
3. Good temperature resistance:
• During the production and use of screen printing silicone, it may experience different temperature environments, such as in the baking and curing stage or in a high temperature use environment. The middle layer needs to have good temperature resistance, be able to maintain stable performance at high temperatures, and not deform, soften, decompose, etc., so as to ensure the quality and service life of the silk screen silicone.
4. Good flexibility:
• It can give the silk screen silicone a certain flexibility so that it can adapt to the surface of substrates of different shapes and materials. For example, in some curved and folded parts, the middle layer with good flexibility can ensure that the silk screen silicone will not break or fall off due to the deformation of the material, and maintain good adhesion and integrity.
5. Strong compatibility:
• It has good compatibility with the bottom and surface materials of the silk screen silicone, and can be integrated and penetrated with each other to form a tight whole. At the same time, the middle layer also needs to have good compatibility with different substrate materials to ensure that the silk screen silicone can be firmly attached to the surface of various materials, such as textiles, plastics, metals, etc.
6. Good water resistance:
• In some humid or water-contact environments, the middle layer of the silk screen silicone needs to have good water resistance to prevent moisture from penetrating into the silicone and affecting its adhesion and stability. For example, in the silk-screen silicone patterns of swimsuits, diving suits and other water sports products, the water resistance of the middle layer is particularly important.
