Lancer Group’s STI7941 Stretch Clear is a silicone adhesive clear that when printed after STI7960 White, 7933 STI Colours or STI7935 High-Density White or high-density colours greatly enhances adhesion on performance-wear garments decorated with silicone heat transfers. Consult separate TDS for mixing catalyst, printing and applying high-density silicone transfers.

STI7941 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, STI7940 Stretch Clear, STI7960 White, STI7933 Colours, STI7935 High-Density White and high-density colours, STI7941 Stretch Underbase, and T-1 Adhesive Powder. Note: All components except STI7902 and T-1 Powder must be catalyzed prior to printing.
