The color paste of screen printing silicone and the color paste of plastisol ink are not exactly the same. The following is a comparative analysis of the two:
1. Ingredients and basic materials
Silk screen printing silicone color paste
Main ingredients: silicone and related additives, such as pigments, dispersants, etc.
Features: Silicone color paste has high high temperature resistance, good weather resistance, stable color, and environmental protection meets the requirements.
Plastisol ink color paste
Main ingredients: usually contains resin, pigment, filler and additives, etc.
Features: Plastisol ink color paste often shows bright colors and high reduction in printing, but it may vary depending on the type of resin and process.
2. Application and effect
Silk screen printing silicone color paste
Application: Mainly used for screen printing of silicone products, such as silicone buttons, silicone bracelets, etc.
Effect: The printed silicone products are bright and durable, and have certain elasticity and softness, which meets the characteristics of silicone products.
Plastisol ink color paste
Application: Widely used for printing of daily clothing, such as T-shirts, POLO shirts, etc.
Effect: It can print a printing effect with full colors and thick patterns, but the feel may be hard and the air permeability is relatively poor.
3. Drying and curing
Silk screen printing silicone color paste: It usually needs to be dried and cured by high temperature baking to ensure the close combination of the color paste and the silicone substrate.
Plastisol ink color paste: The drying and curing methods may vary depending on the specific process and product requirements, but it usually does not require high temperature baking like silicone color paste.
4. Other characteristics
Silk screen printing silicone color paste: Due to the characteristics of silicone itself, the color paste needs to maintain high fluidity and stability during the printing process to ensure the clarity and uniformity of the printing effect.
Plastisol ink color paste: During the printing process, more attention may be paid to the dispersion of the pigment and the binding with the resin to ensure the vividness and durability of the printing effect.
In summary, there are significant differences between the color paste of screen printing silicone and the color paste of glue in terms of composition, application and effect, drying and curing and other characteristics. Therefore, when selecting and using, it is necessary to make comprehensive considerations based on specific printing needs and material characteristics.
