3501 vs 3565 vs 1206<\/strong> is a system-and-evidence comparison, not a slip ranking. The public pages position 3501 broadly for printing and release but give no dose, give 3565 two conflicting dose statements plus a pinhole warning, and restrict 1206 to UV and solvent systems. Define the print failure and vehicle before testing.<\/p>\n

Keep 3501 behind a dosage gate<\/h2>\n

3501\u2019s page lists printing inks, inkjet inks, overprint varnishes, release coatings and anti-sticking uses. That establishes possible application relevance, not an optimum dose. Ask for the current TDS, active content, starting range, compatible vehicles and a pressure\/temperature\/time blocking method. Do not invent an equal-dose comparison with the other two grades.<\/p>\n

Resolve 3565\u2019s conflicting dose statements<\/h2>\n

The same 3565 page gives \u201crecommended dosage 0.05\u20131%\u201d and later \u201cdosage 0.02\u20133% of total formulation.\u201d These ranges are not interchangeable. Confirm whether one is a general envelope, an application-specific range or a translation error. Record the supplier-approved basis before trial work. Preserve the instruction to add before the curing agent and the explicit pinhole warning.<\/p>\n

Exclude 1206 from waterborne work<\/h2>\n

1206 is eligible for UV and solvent systems but its page marks water-based systems with an exclusion. It is recommended at 0.1\u20131.0% total and near the end of formulation, with optional alkane or aromatic predilution. The page also warns of cloudiness with dimethyl silicone oil and low-temperature haze that clears on heating. Recheck performance after any recovery.<\/p>\n

Separate blocking, rub and abrasion<\/h2>\n

Blocking is adhesion between printed surfaces under pressure, heat and time. Rub is damage from repeated contact with a receptor. Abrasion is progressive wear under a specified wheel or medium. These are different failure modes. A grade that improves release can reduce intercoat adhesion or change friction, and a title that mentions abrasion resistance is not a quantified result.<\/p>\n

Normalize print density first<\/h2>\n

ASTM D7305<\/a> describes reflection-density measurement on printed paper, film or board. Match density before comparing rub, gloss or blocking; otherwise different ink transfer can look like an additive benefit. The method is not intended for metal or foil, so use an appropriate documented alternative for those substrates.<\/p>\n

Use a defined rub method<\/h2>\n

ASTM D5264<\/a> provides a comparative Sutherland rub practice for printed materials. Fix receptor, load, cycles and conditioning. Run blocking separately under realistic rewind or stack pressure, temperature and dwell. Report failure mode rather than only a pass\/fail label.<\/p>\n

Keep the vehicle and curing process visible<\/h2>\n

ASTM D6687<\/a> guides testing of printing-ink vehicles and components. Record resin, pigment, solvent or water balance, UV dose when applicable, film thickness and cure state. For 3565, test the prescribed pre-curing-agent addition against a control. For 1206, test late addition and any predilution as separate process variables.<\/p>\n

Do not infer packaging compliance<\/h2>\n

None of these pages proves food-contact, pharmaceutical-contact, low-migration or destination-market compliance. Map direct contact, indirect contact and set-off. Obtain the applicable composition and regulatory declarations and validate the complete printed construction. Performance in a packaging-ink table is not regulatory clearance.<\/p>\n
