How to Apply Silicone Heat Transfer Labels (Step-by-Step Guide)
Silicone heat transfer labels (or patches) are 3D rubber-like logos pressed onto fabrics using heat. They are durable, flexible, and waterproof, making them ideal for sportswear, brand labels, and custom apparel.
1. Materials Needed
✅ Silicone transfer labels (pre-made or custom-molded)
✅ Heat press machine (or industrial flat press)
✅ Teflon sheet (or silicone-coated parchment paper)
✅ Fabric garment (cotton, polyester, or blends work best)
✅ Infrared thermometer (optional, for accurate temperature check)
2. Step-by-Step Pressing Instructions
Step 1: Prepare the Garment
Pre-press the fabric for 3–5 seconds at 150°C (302°F) to remove moisture and wrinkles.
Avoid starch or fabric softeners (they reduce adhesion).
Step 2: Position the Silicone Label
Place the silicone logo face-up on the garment.
Use heat-resistant tape to secure it (prevents shifting).
Step 3: Cover with Teflon Sheet
Place a Teflon sheet or silicone-coated parchment paper over the logo to protect it.
Step 4: Heat Press Settings
| Parameter | Recommended Setting |
|---|---|
| Temperature | 160–180°C (320–356°F) |
| Pressure | Medium to high (40–60 PSI) |
| Time | 10–20 seconds (adjust based on thickness) |
Step 5: Press the Silicone Label
Close the heat press firmly and apply heat for 10–20 sec.
For thick silicone logos, press 15–25 sec at 170°C (338°F).
Step 6: Peel & Cool
Hot peel (immediately) → For a glossy finish.
Cold peel (after cooling) → For a matte finish.
Let the garment cool before wearing or washing.
3. Troubleshooting Common Issues
| Issue | Solution |
|---|---|
| Logo not sticking | Increase temperature (max 180°C) or press longer. |
| Silicone cracking | Reduce pressure or temperature; check fabric compatibility. |
| Fabric scorching | Lower temperature; use a Teflon sheet for protection. |
| Edges lifting after wash | Ensure full adhesion by pressing longer (20 sec). |
4. Best Fabrics for Silicone Labels
✔ Cotton, polyester, cotton-poly blends (best adhesion)
✔ Nylon, spandex (works but may require higher temp)
❌ 100% silicone-coated fabrics (poor adhesion)
❌ Delicate fabrics like silk (may burn)
Final Tips
Test first on a scrap fabric to optimize settings.
Store silicone labels in a cool, dry place (avoid humidity).
Wash inside-out to prolong logo life.
