Why Does Screen Printing Glossy Silicone Peeling Happen?

    In recent years, glossy silicone ink has become increasingly popular in textile screen printing due to its smooth surface, high shine, and premium appearance. It is widely used on T-shirts, fleece fabrics, sportswear, waterproof garments, and shoes.

However, some manufacturers report a common issue:

Why does glossy silicone printing peel off easily?

This article explains the real cause and the correct solution.

    First, it is important to understand the structure of glossy silicone printing.

    Glossy silicone ink is mainly used as the final top coating layer to create a bright and smooth surface effect. It is not designed to function as the main bonding layer.

    In a typical direct screen printing process, the structure usually includes:

• base layer (primer)
•  Middle transparent or build-up layer
•  Glossy top coating layer

If the bottom bonding layer is weak or missing, the entire print - including the glossy surface - may peel off.

Peeling does not happen because the glossy silicone is weak.

It happens because:

• No adhesion primer was applied
• Incorrect base silicone was used
• Fabric surface was not suitable
• Curing temperature was insufficient
• Layer thickness was not balanced

Especially on nylon, waterproof fabrics, or smooth synthetic textiles, printing glossy silicone directly without a primer will cause poor adhesion.

To make glossy silicone printing strong and durable, the key is the bottom layer.

Apply Adhesion Base (Primer)

For difficult fabrics such as:

• Nylon
• Waterproof materials
• Coated fabrics
• Shoe materials

An adhesion base layer must be printed first. The primer improves bonding strength between the fabric and the silicone system.

Use Proper Middle Layer Support

Before applying glossy top coating, print a transparent or build-up silicone layer to create stable structure and thickness.

Control Curing Temperature

Recommended curing temperature:
130–150°C, depending on silicone system.

Insufficient heat curing may result in incomplete cross-linking, which reduces bonding strength.

    Glossy silicone ink is designed to provide a beautiful high-gloss finish on the surface.

    If peeling occurs, the problem is usually not the glossy layer itself - but the missing or weak adhesion base underneath.

For long-lasting glossy screen printing results, always:

• Use proper adhesion primer
• Build a stable middle layer
• Control curing temperature correctly

With the right printing structure, glossy silicone can achieve excellent durability, flexibility, and wash resistance.
