There are indeed some differences in the stickiness of silicone lettering film and silk-screen silicone, which are mainly due to their material composition and application characteristics.
Stickiness of silicone lettering film
Strong adhesion: Silicone lettering film is usually made of high-quality silicone material and special coating, which enables the lettering film to adhere firmly to various material surfaces, including metal, plastic, glass, etc.
Resettable and positionable: The back layer of some silicone lettering films has an adhesive high-temperature resistant PET film. This design allows the lettering film to be reset and positioned during the lamination process to ensure the accuracy and clarity of the lamination.
Good weather resistance: The stickiness of silicone lettering film is not only strong, but also has good weather resistance. It can maintain a stable adhesion effect in various environments and is not easy to fall off.
Screen printing silicone stickiness
Moderate adhesion: The stickiness of silk-screen silicone is usually moderate, which can be firmly attached to the printed substrate, but will not be difficult to operate or damage the substrate due to excessive stickiness.
Strong adaptability: Screen printing silicone can adapt to a variety of printing substrates, including textiles, leather, plastics, etc., and has a wide range of applicability.
Adjustability: The viscosity of screen printing silicone can be adjusted to a certain extent by adjusting the formula and printing process to meet the needs of different customers.
The impact of viscosity differences
Application scenarios: Due to the difference in viscosity, silicone lettering film is more suitable for occasions that require long-term adhesion and have high requirements for adhesion, such as electronic product logos, car logos, etc. Screen printing silicone is more suitable for occasions that require moderate adhesion and have high requirements for substrate friendliness, such as clothing, luggage, etc.
Convenience of operation: Due to the characteristics of reset and positioning, silicone lettering film makes operation more convenient during the lamination process, reducing waste caused by inaccurate lamination. Screen printing silicone requires more sophisticated operating skills to ensure the stability of printing effect and adhesion.
In summary, there are differences in viscosity between silicone lettering film and screen printing silicone, which make them suitable for different application scenarios and operating requirements. When choosing, comprehensive consideration should be given to the specific application scenario, substrate type and required adhesion requirements.
