OPTI 934B Retarder (formula T-934B) is the slow-drying additive for the 40000 Gloss and 43000 Matte vinyl inks. Added in small amounts, it keeps vinyl ink open in the mesh and improves flow in hot, humid conditions.

⚠ Industrial use only. An industrial solvent ink additive — keep away from apparel and skin contact.

Add 3–5% by weight. Quart, gallon and 5 gallon. Made in Hackensack, New Jersey.

What it does
