YRsilicone XG-866A-8 is a heat transfer silicone ink developed for high-build transfer applications. Its main advantages are fast build-up and easy forming, helping manufacturers create clear raised effects with a controlled screen printing process. XG-866A-8 can be used on cotton, nylon, polyester, slightly silicone-treated fabrics, and coated waterproof nylon fabrics.
Key Features of XG-866A-8
★ Fast build‑up and easy forming: Gain clear thick layers after several printing passes, good for raised 3D‑style transfer patterns.
★ Suitable for professional production: The complete transfer system provides defined printing and heat-press procedures for production testing.
★ Supports two mainstream workflows: forward (positive) transfer and reverse transfer printing.
★ Can mix with color paste to get rich custom colors; supports glossy or matte top finishes.
★ Good flexibility and wash resistance after full heat cure.
XG-866A-8 Heat Transfer Silicone System
XG-866A-8 is used as part of a complete transfer silicone system rather than as a standalone material.
The product system includes:
● XG-360R-012 – Hot melt adhesive
● XG-360Z-3X – Intermediate silicone
● XG-866B-2 – Additive
● XG-866A-8 – Transfer high-density silicone
● XG-399HR – Gloss silicone
● XG-866M-6+ – Matte skin-feel silicone
The exact combination can be selected according to the required transfer structure and surface effect.
Forward (Positive) Heat Transfer Steps
1, Print XG‑360R‑012 hot‑melt glue for 4‑6 times.
2, Mix XG‑360Z‑3X middle‑layer glue with 10 % XG‑866B‑2 middle‑layer assistant; print for 2 times.
3, Blend XG‑866A‑8 transfer silicone ink with 3 % XG‑866B‑2 transfer assistant. Print 3‑4 times until transparent. Then add 10‑20 % color paste for coloring. Adjust printing times according to your sample effect.
4, Print top‑coat silicone (XG‑399HR glossy or XG‑866M‑6 matte + 3 % assistant) for 2‑3 times.
5, After all layers surface‑dry, place printed PET film in sealed oven at 100 °C for 40 minutes for full curing.
6, Heat‑press transfer onto fabric: 120‑150 °C, 15 seconds.
Reverse Heat Transfer Steps
1, Mix XG‑866A‑8 with 3 % XG‑866B‑2 transfer assistant plus 10‑20 % color paste. Print layers to reach your target visual effect.
2, Mix XG‑360Z‑3X middle‑layer glue with 10 % XG‑866B‑2 middle‑layer assistant; print for 2 times.
3, Print XG‑360R‑012 hot‑melt glue for 4‑6 times.
4, After full surface‑dry, bake printed PET film in sealed oven at 100 °C for 40 minutes.
5, Heat‑press onto target fabric at 120‑150 °C for 15 seconds.
6, Final surface gloss or matte look depends on your PET transfer film type.
Conclusion
XG-866A-8 Heat Transfer Printing Silicone Ink is a practical solution for manufacturers who need fast thickness build-up and easy forming in silicone transfer printing. It can be used in both positive and reverse heat transfer processes, with different layer structures available according to the production method and desired surface effect.
For professional screen printing factories, the right combination of transfer silicone, intermediate layer, adhesive, pigment, PET film, curing, and heat-press conditions is the key to achieving a stable final result.
YRsilicone can provide silicone materials and technical support for different textile transfer requirements, from sample development to bulk production.
