There are significant differences between screen printing silicone and oily silicone in many aspects. The following is a detailed comparison of the two:
1. Definition and characteristics
Screen printing silicone
Definition: Screen printing silicone is a special silicone that can be firmly adhered to the surface of textiles, non-woven fabrics, leather, imitation leather and other materials through screen printing technology.
Characteristics: It has the characteristics of high transparency, high strength, high tear resistance, soft feel, strong adhesion, etc. In addition, the screen printing silicone pattern has a strong three-dimensional sense, excellent wear resistance and brightness, and is waterproof, non-slip, breathable, resistant to high and low temperatures, and has good leveling properties.
Oily silicone
Definition: Oily silicone is a polymer material made based on high molecular organic polymers. A large amount of silicone oil is added during the production process, which makes it have excellent oiliness and waterproofness.
Characteristics: It has rubber-like viscosity, elasticity and high temperature resistance, can maintain elasticity at low temperatures, and can withstand the erosion of many chemicals. Oily silicone also has excellent peel strength, wear resistance and water washing fastness.
2. Application fields
Silk-screen silicone
Mainly used in surface coating and decoration of textiles (such as clothing labels, clothing patterns, etc.), leather products (such as handbags, travel bags, luggage, etc.) and high-end electronic products.
Oil-based silicone
The application range is wider, including high-temperature sealing, bonding, insulation, corrosion-resistant materials, as well as automobile manufacturing, electronic appliances, medical industry, aerospace and other fields. In addition, oil-based silicone is also often used for silk-screen printing on fabrics to make patterns with three-dimensional sense and soft feel.
3. Operation and process
Silk-screen silicone
Usually, it is necessary to mix components A and B evenly in a certain proportion, and then apply them to the substrate through screen printing technology. After curing, a pattern with a strong three-dimensional sense and soft feel can be formed.
Oil-based silicone
Suitable for various printing methods such as manual table silk-screen printing, rotary table silk-screen printing and ribbon machine printing. During the printing process, oil-based silicone can firmly adhere to the surface of textiles to form patterns with excellent performance. In addition, oil-based silicone can also be printed in color, breaking the bottleneck of single color.
4. Environmental protection and safety
Silk-screen silicone: As an environmentally friendly material, silk-screen silicone is non-toxic and harmless, and has no adverse effects on the human body and the environment.
Oil-based silicone: It also has environmental protection characteristics, is non-toxic and harmless, and can be printed in color, does not fade when printing in color, and can print a variety of effects (such as gloss, matte, etc.).
In summary, there are significant differences between silk-screen silicone and oil-based silicone in terms of definition and characteristics, application areas, operation and process, and environmental protection and safety. When choosing which silicone to use, comprehensive consideration should be given to the specific application needs and process requirements.
