Lancer Group’s STI7950 Silicone High Opacity Mixing Base is an opaque base that when mixed with Evolution Pigment Concentrates produces Pantone, STI7933 colours or custom colours. Even though this ink is opaque (except Glow-in-the-Dark) and bleed-resistant on many fabrics, for sub-dye polyester and other fabrics known for dye migration, it may be necessary to back this with STI7911 Defender Black Dye Blocker. Multiple coatings of direct emulsion, capillary films or a print/flash/print technique during printing may be needed to achieve desired effect.

STI7950 is part of the STI Silicone Heat Transfer System. Other components in this system that are necessary to produce silicone heat transfers are PET Film, STI7960 White, STI7940 Stretch Clear, STI7933 Colours, STI7941 Stretch Underbase, and T-1 Adhesive Powder. Note: All components except T-1 Powder must be catalyzed prior to printing

Always test finished prints for curing, adhesion, opacity, bleed-resistance and desired look prior to beginning full production runs. Lancer Group International cannot guarantee the results or back claims that this ink will test PVC-free or phthalate-free if any additive other than an additive manufactured by Lancer Group International is used to modify this ink. Test results by a third-party laboratory verifying all components used to produce this ink are PVC-free, phthalate-free and lead-free are available upon request.
