Screen printing silicone is widely used in webbing, apparel, gloves, footwear, and even electronic products to provide anti-slip, decorative, and durable effects.
However, the silicone you buy is not ready-to-use as a final product – it needs to go through a curing process to turn it into a stable, durable pattern.
1. Why Curing Is Essential for Screen Printing Silicone
Curing is the process of crosslinking the silicone molecules, turning it from a flowing liquid into an elastic, durable solid pattern.
After curing, screen printing silicone offers:
Strong adhesion – patterns stay firmly attached without peeling
Excellent durability – resistant to high/low temperature and aging
Wash & abrasion resistance – perfect for apparel and webbing applications
Smooth appearance – sharp edges, bright colors, and 3D effects
Simply put, curing transforms silicone from a liquid ink into a permanent, functional decoration.
2. Main Curing & Molding Methods for Silicone
Silicone can be cured and molded in several ways, depending on the product requirements:
1) High-Temperature Compression Molding (Solid Silicone)
Solid silicone is mixed with curing agents and vulcanized under high temperature and pressure in a mold.
Advantages: High precision, stable quality, suitable for mass production
Applications: Keypads, gaskets, industrial parts
2) Liquid Silicone Injection Molding
Two-component liquid silicone (LSR) is automatically mixed and injected into the mold, then cured under heat.
Advantages: Fully automated, highly accurate, efficient
Applications: Baby nipples, medical tubes, precision electronic parts
3) Room-Temperature Curing (RTV Silicone for Screen Printing)
Most screen printing silicones use room-temperature vulcanizing (RTV) silicone, which can cure at ambient conditions or faster under heat.
(a) One-Component RTV Silicone
Packed under vacuum, cures when exposed to moisture in the air
Mostly used for bonding and sealing applications
(b) Two-Component RTV Silicone
This is the most common choice for screen printing silicone. The A & B components are mixed before printing, and the printed pattern cures at room temperature or with heat.
Industrial-grade silicone: Tin-catalyzed, cures at room temperature, little affected by temperature changes
Food-grade silicone: Platinum-catalyzed, can cure at room temperature or faster with heat, ideal for high-volume production
This method is perfect for printing on webbing, apparel, gloves, and other substrates, achieving various effects such as matte, glossy, anti-slip, or 3D textures.
3. Conclusion
Curing is the key step that ensures screen printing silicone patterns are durable, flexible, and visually appealing.
Choosing the right curing method not only improves product quality but also increases production efficiency.
