Liquid injection silicone and screen printing silicone color paste are essentially materials used to color silicone, but they are not exactly the same. The following is a detailed comparison of the two color pastes:
1. Usage scenarios and processing methods
Liquid injection silicone color paste:
Mainly used in the injection molding process of liquid silicone.
Maintain a certain fluidity to facilitate uniform mixing with liquid silicone.
Can be mixed with silicone by a mixer or automatic feeder, and then injected for processing.
Screen printing silicone color paste:
Mainly used in the screen printing process of silicone products.
The color paste is required to have good printing performance and color brightness.
Usually used for decorative printing such as patterns and texts on the surface of silicone products.
2. Performance requirements
Liquid injection silicone color paste:
It needs to have good compatibility with liquid silicone to ensure that there will be no stratification, precipitation, etc. after uniform mixing.
It needs to have high dispersibility and stability to ensure that the color of the injected silicone products is uniform and lasting.
Screen printing silicone color paste:
It needs to have good printing suitability, such as appropriate viscosity and fluidity, to ensure the clarity and integrity of the printed pattern.
It needs to have high weather resistance and wear resistance to ensure that the printed pattern is not easy to fade or wear during use.
3. Selection suggestions
When choosing liquid injection silicone color paste, the compatibility, dispersibility and stability with liquid silicone should be considered.
When choosing screen printing silicone color paste, the factors such as printability, weather resistance and wear resistance should be considered.
In summary, although the color pastes of liquid injection silicone and screen printing silicone are both materials used for silicone coloring, they have different performance requirements due to different usage scenarios and processing methods. Therefore, when choosing color pastes, it is necessary to consider and select according to specific usage requirements.
