SB Series pad / screen printing ink is a specialized, excellent-adhesion 1- or 2-component flexible ink for rubber, rubber-like or soft-touch surfaces. This series’ unique elasticity, high gloss and opacity make it the ideal choice for printing on items such as stress balls, rubberized pens, Crocs, soft-touch travel mugs, koozies, can coolers, simulated leather and vinyl items as well as other flexible or coated products. Like all Sapphire® series, SB complies with European EN 71 Toy Safety standard and California Proposition 65.

Substrates: Typical Applications:
Polyurethane based materials
Flexible substrates
Stress balls
Play balls & sporting goods
Skateboard Wheels
"Soft Touch" surfaces
Soft PVC
Tagless T-shirts
ID Cards
Binders & report covers

Another popular application for SB series ink is tag printing. This textile ink is perfect for pad or screen tag printing on tagless t-shirts, sweatshirts and other tagless garments.

Benefits of tag printing over heat transfer:
  • While heat transfer just puts markings on the garment’s surface, SB ink penetrates and saturates textile thus extending the life of the tag. SB ink is very durable even when used as a 1 component ink; with hardener, it will withstand copious industrial washings.
  • With heat transfer, labels have to be purchased by thousands; with screen or pad tag printing, the image can be easily modified in-house, enabling cost-effective short-run production.

Mixing Preparation
(2 component usage optional)

Hardeners: SB Series ink for rubber items and tag printing cures by air drying and cross-linking. Add 1000H Hardener at a ratio of one part hardener to ten parts ink (10:1) by weight. SB Series ink (when using hardener) has a 7/8 hour working pot life.

Solvent: Immediately after adding the hardener the mixture should be thinned to printing viscosity with 10% - 30% SB-M or SB-MS by weight. Adding solvent will make the ink less viscous and dry slower.

Drying: SB Series flexible ink for rubber items and tag printing cures by air drying or chemical cross-linking. It will be ready for overprinting in less than 60 seconds and will be dust dry in 20 minutes at room temperatures. Complete cross-linking (full cure) of the inks is realized in 6-8 days at room temperatures. Dust dry and full cure conditions can be significantly accelerated by the application of heat.

Retarder: For fine prints, add SB-MS retarder in proportions not to exceed 50% by weight of solvent. Adding too much retarder may inhibit ink transfer from pad to substrate.
