Anti-Migration Silicone Ink for Sublimated Polyester
Designed to control dye migration and color contamination on sublimated polyester fabrics, this series serves as a technical barrier base coat for high-volume garment decoration.
The Mechanism: Formulated with high-density activated carbon technology to intercept migratory disperse dyes, preserving top-layer color accuracy, brightness, and long-term print quality.
The Production Impact: Engineered for automated, high-volume production lines to ensure consistent rheology and processing stability on challenging polyester substrates.
The Supply Assurance: Direct-manufacturer supply providing the strict lot-to-lot consistency and scalable output required for global brand workflows.

Feature Essentials & Performance
Our premium anti-migration silicone ink prevents dye migration on dark fabrics while preserving exceptional elasticity and a soft hand feel.
Disperse Dye Blocking
Formulated for polyester, spandex, and softshell substrates. Effectively blocks dye migration to maintain absolute color fidelity for top-layer prints.
>500% Elongation
Flexes continuously with the fabric. Prevents mechanical cracking under extreme stretch, resolving the failure rates of traditional rigid blockers.
Cross-Linked Adhesion
Forms a secure chemical bond between the fabric and top-coat inks. Eliminates delamination and peeling risks during heavy wear or industrial washing.
Low-Profile & Compliant
Applies as a thin structural coating to preserve natural fabric drape. 100% solvent-free and heavy-metal-free, ensuring certified safety for direct skin contact.

Operational Process
The “Sandwich Method” is critical for success on polyester.
Step 1: The Foundation (Linker)
If printing on waterproof nylon or slippery polyester, print 1 layer of Silicone Linker first to ensure adhesion. Flash dry.
Step 2: The Barrier (Anti-Migration)
Mix Anti-Migration Base + Catalyst (10:1).
Print: Use an 86-100 mesh screen. Print 2 layers (Print-Flash-Print).
Expert Tip: Do not over-flash! Flash at 100°C for just 5-8 seconds. Excessive heat during flashing wakes up the fabric dye and causes it to migrate before you even finish printing.
Note: The print will look dark grey. This is normal.
Step 3: The Background (White),The Design & Color
Print your High-Opacity White Silicone on top of the grey blocker.
Print 2-3 layers until the grey is completely covered and the white is brilliant.
Print your final colors (Red, Blue, High Density, etc.) on top of the white.
Step 4: Final Cure
Bake at 140°C – 150°C for 90 seconds.
Warning: Keep temperature as low as possible (140°C is safer for poly) to prevent late-stage migration.
Primary Fabrics
Why use it here? These fabrics release dye gas when heated (migration). Without this blocker, your print is ruined.
100% Polyester
Football jerseys, basketball kits.
Sublimated Fabrics
Custom-printed activewear with chaotic patterns.
Softshell Jackets
High dye content outerwear.
Nylon/Spandex Blends
Dark colored yoga pants.

Customer Case Study
Client: Sportswear Manufacturer (Germany)
The Challenge: White prints on sublimated red polyester substrates exhibited severe dye migration during standard warehouse storage, resulting in a €50,000 liability claim due to product rejection.
The Solution: Integrated our Carbon-Grey Anti-Migration Silicone as a structural barrier underbase.
The Outcome:
Migration Control: Effectively mitigated disperse dye bleeding, maintaining strict color fidelity over extended storage periods.
Mechanical Flexibility: Retained required high-elongation properties to support high-stress athletic movement without cracking.
Validation Passed: Successfully met the brand’s accelerated aging protocols (7 days at 60°C oven validation).
FAQ – Troubleshooting
Q1: Why is the anti-migration silicone black/grey?
A: It contains activated carbon, which is the most effective material for absorbing loose dye molecules. You must cover it with white silicone.
Q2: Can I use this on cotton?
A: You can, but it’s unnecessary. Cotton dyes (reactive dyes) do not migrate/bleed like polyester dyes. Save your money and use standard silicone for cotton.
Q3: What happens if I cure it at 180°C?
A: Yes, our formula is Phthalate-Free and Lead-Free, making it compliant with CPSIA regulations for children’s apparel.
Q4: Does this product contain PVC?
A: No. Unlike the old “Grey Blocker Plastisol,” our product is 100% Silicone, PVC-free, and Phthalate-free.
Q5: Can I mix the Anti-Migration Carbon base directly into my white silicone ink to save a printing step?
A: No, we strongly advise against this. To effectively block dyes, the activated carbon must form a concentrated base layer (the shield). Mixing it into your white ink dilutes its absorption power and will turn your top-coat white into a permanent muddy grey. For maximum protection, always follow the “Sandwich Method”: Print the pure blocker first, flash, and then overprint with High-Opacity White.
