Silicone screen printing ink is a high-performance ink designed for silicone, rubber and elastomer materials, and is widely used in footwear, clothing, sports equipment and other fields. Its unique formula and performance make it an ideal choice for printing patterns on uppers.
1. Product Features
High adhesion and wear resistance
Silicone ink forms a strong bond with the surface of silicone material through chemical bonding, ensuring that the pattern is not easy to fall off under repeated bending and friction.
Abrasion resistance tests show that the printed pattern can withstand more than 50 industrial-grade water washings or 100,000 bending tests.
Excellent flexibility and elasticity
The elastic modulus matches the silicone substrate, and the printed layer expands and contracts with the material without cracking, which is suitable for high deformation areas such as uppers and soles.
Environmental protection and safety
Complies with international environmental protection standards such as REACH and RoHS, does not contain harmful substances such as PVC and phthalates, and is suitable for children's footwear and sports equipment.
Weather resistance and chemical resistance
Resistant to UV, ozone and sweat corrosion, the printed pattern will not fade or deform after long-term use in outdoor environments.
2. Application fields
Footwear manufacturing: LOGO and pattern printing of sports shoes, casual shoes and rain boots.
Sports equipment: personalized customization of protective gear, gloves and swimming caps.
Clothing accessories: printing of silicone labels and reflective strips.

4. Usage suggestions
Surface treatment
Before printing, the silicone surface needs to be plasma treated or a special primer should be used to improve adhesion.
Printing process
It is recommended to use a 300-350 mesh screen, a scraper hardness of 70-80 Shore A, and a printing pressure of 2-3 kg/cm².
Curing conditions
It needs to be evenly heated in an infrared tunnel furnace to avoid local overheating that causes ink embrittlement.
Post-treatment
After curing, the surface can be wiped with alcohol to remove residual ink and improve gloss.
5. Precautions
Storage conditions: sealed and protected from light, temperature 5-25℃, shelf life 6 months.
Safety tips: Wear protective gloves during operation to avoid contact with skin and eyes.
Compatibility test: Sample test is required before large-scale production to ensure compatibility with the substrate and subsequent processes.
6. Market trends
With the growing demand for personalized customization of sports shoes, the application of silicone screen printing inks in the fields of special functional inks such as 3D stereoscopic effects, fluorescent luminous, and temperature change will be further expanded. At the same time, the research and development of bio-based silicone inks also meets the market demand for sustainable development.
By choosing the right silicone screen printing ink, footwear manufacturers can achieve efficient, environmentally friendly and durable pattern printing, and increase product added value.
