How to Choose Additives for Waterborne Lamination Inks

July 31, 2026 marketing@longchang Group

Quick answer: buyers choosing additives for waterborne lamination inks usually get a cleaner first shortlist when they separate three different jobs instead of asking one additive to rescue every print and converting defect at once. Start with CHLUMIWE® 2100 when the waterborne lamination ink still needs better film-surface wetting, spread, and calmer entry on film or coated web stock. Move CHLUMIAG® 3501 forward when the ink already prints directionally but the dried print face still needs anti-sticking, release, or handling control before lamination. Start with CHLUMIAF® 3062 when the real bottleneck is foam, microbubbles, or process-side air release in a waterborne lamination-ink route.

This page stays inside the redirected CHLUMICRYL® Coating and Ink Additives direction and does not fall back to the older photoinitiator cluster. It also is not a duplicate of Longchang’s already-live waterborne flexographic ink additives or waterborne gravure ink additives pages. Those pages are process-first. The buyer question here is narrower: which additive deserves the first trial when the ink is specifically waterborne, used in a lamination-oriented packaging route, and still not giving a commercially stable result before the laminated structure is built?

Why waterborne lamination inks deserve their own additive page

A waterborne lamination ink sits in a tighter buyer lane than a broad flexographic or gravure article because the project has to keep together film-surface entry, dried-print handling before the lamination step, and water-based process stability. A drawdown may look directionally acceptable while the live job still loses quality because the ink does not wet the film cleanly, the dried print face still blocks or drags before lamination and rewinding, or the letdown and circulation route keeps carrying foam into the system.

That makes waterborne lamination a publishable application split instead of another generic packaging-ink article. Buyers often need to separate a film-wetting problem, a dried-print handling problem, and a waterborne foam problem before they can judge the rest of the ink package honestly. Those are different first screens, even when one trial roll seems to show more than one symptom together.

General industry framing supports that split conservatively. Flexible-packaging and lamination-oriented ink programs are commonly judged for substrate entry, print-face handling through converting, and stable low-foam circulation rather than by one vague additive score. The product-specific facts below still stay tied to current Longchang-supported product pages.

What the current company-supported evidence actually separates

  • CHLUMIWE® 2100 is supported by Longchang for printing inks, overprint varnishes, and inkjet inks, with a recommended dosage of 0.1% to 1.0%, addition during grinding, stirring, or after production, optional pre-dilution, and applicability across UV, solvent, and water-based systems. That gives buyers a practical first route when the main issue is still film-surface wetting and spread.
  • CHLUMIAG® 3501 is the broader anti-sticking and handling route. Longchang supports it as a multi-component modified polysiloxane that can be added at any stage or later and used across UV, solvent, and water-based systems. Current Longchang-controlled usage tables place it in printing inks, inkjet inks, overprint varnishes, release coatings, and anti-sticking-agent use, which is a clean fit when the printed face already forms but still handles poorly before lamination or rewinding.
  • CHLUMIAF® 3062 is the defoamer-first route. Longchang supports it as a polyether-modified polysiloxane defoamer for printing inks, with a recommended dosage of 0.1% to 0.5% of total formulation and applicability across UV, solvent, and water-based systems. The current product page also adds a practical note that if solvent dilution is used, stability and defoaming performance should be tested first.

That is enough company-supported separation to build a real B2B buyer page without inventing unsupported lamination-bond, migration, or compliance claims. The goal is not to claim one additive fixes every waterborne lamination complaint. The goal is to help the buyer choose the first better trial route.

Quick comparison table: which route deserves the first screen?

Buyer priority in waterborne lamination inks Best first route Why it belongs first Main watchpoint
The ink still hesitates on film, coated stock, or another less absorbent web surface CHLUMIWE® 2100 Longchang directly supports it for printing inks with flexible addition timing and water-based compatibility Use it when the first problem is still substrate entry and spread, not when the real complaint only starts later during handling before lamination
The ink already lays down directionally, but the dried print face still blocks, drags, or handles poorly before lamination or rewinding CHLUMIAG® 3501 Longchang directly supports it for printing-ink use, anti-sticking logic, and broader handling across water-based systems Do not use it to hide a true wetting problem if the print still is not entering the film cleanly
Foam, microbubbles, or air release are still disturbing press stability or final print appearance CHLUMIAF® 3062 Longchang directly positions it as a printing-ink defoamer with a defined waterborne-compatible dosage window It is a defoaming route, not the first answer to a missing wetting route or a dried-face handling problem

When CHLUMIWE® 2100 is the better first move

2100 should move first when the waterborne lamination project still looks like a film-wetting problem. This is the cleaner starting route when the ink reaches the converting line, but the wet film still hesitates, spreads unevenly, or does not settle onto the web the way the buyer needs.

That distinction matters because lamination-oriented projects often show more than one complaint at once. A printed face that does not wet or spread properly can also look harder to handle later simply because the first contact was never right. If the first visible problem is still entry and spread, later handling or defoaming trials become harder to read honestly.

  • Best first-screen use: film-surface wetting and spread in waterborne lamination inks
  • Supported dosage window: 0.1% to 1.0% of total formulation
  • Addition logic: during grinding, stirring, or after production, with optional pre-dilution
  • Main caution: keep it as the first move when visible substrate entry is the dominant bottleneck, not when the real complaint only starts after drying

In short, 2100 is the better first move when the real question is still how the waterborne lamination ink meets the film or coated web surface.

When CHLUMIAG® 3501 is the better first move

3501 should move ahead first when the ink already prints directionally but still shows a dried-print handling problem. This route is stronger when the issue is not basic wetting, but blocking, sticking, release-oriented handling, or other downstream contact pressure before lamination, slitting, or rewinding.

That matters in waterborne lamination inks because many jobs are not finished when the printed web simply looks acceptable at first glance. The dried surface still has to behave through the next converting step. Longchang’s current controlled usage tables are helpful here because 3501 is not positioned only as a narrow coating additive. The supported route keeps together printing inks, overprint varnishes, release coatings, and anti-sticking use, while staying open across UV, solvent, and water-based systems.

  • Best first-screen use: anti-sticking, release, and downstream handling control after the waterborne lamination ink already lays down directionally
  • Addition logic: can be added at any stage or later
  • Main strength: one route that already supports printing-ink use plus broader handling logic
  • Main caution: if the print still has an obvious wetting failure, 3501 should not be used to hide a problem that still belongs to the 2100 route first

So 3501 is the better first move when the waterborne lamination project needs a handling-first cleanup route after visible laydown is already directionally acceptable.

When CHLUMIAF® 3062 is the better first move

3062 should move ahead first when the waterborne lamination line is being limited by foam, microbubbles, or air release. In those cases, a better wetting route or a better handling route usually will not give the team an honest print read until the foam pressure is under control.

Longchang’s current product page is direct here. 3062 is positioned as a printing ink defoamer, supports a 0.1% to 0.5% dosage window for printing inks, and remains open to water-based systems. That makes it commercially useful in waterborne lamination workflows where letdown, pumping, chambers, or circulation can keep feeding air into the ink even after a small drawdown looks acceptable.

  • Best first-screen use: persistent foam, microbubble carry-through, or waterborne air-release problems in lamination inks
  • Supported dosage window: 0.1% to 0.5% of total formulation for printing inks
  • Main strength: a defoaming route directly tied by Longchang to printing inks and water-based systems
  • Main caution: if solvent dilution is used, test stability and defoaming performance before scale-up

This is the stronger first move when the visible defect is being limited by air management, not by missing film wetting or dried-print handling control.

How buyers should choose before requesting samples

1. Start with the real first failure on the converting line

If the waterborne lamination ink still hesitates on film or coated web stock, start with 2100. If the print already looks directionally acceptable but still blocks or drags before lamination, move 3501 forward. If foam or microbubbles are still corrupting the print read, start with 3062.

2. Keep film-entry control separate from dried-print handling

A waterborne lamination ink that still does not wet cleanly on film and a waterborne lamination ink that prints acceptably but still blocks before the next converting step are not the same additive problem. Separating those routes early usually makes the first trial set much more honest.

3. Keep foam control separate from both surface routes

Defoaming is not just a smaller version of wetting correction or anti-sticking control. If entrained air is still sitting in the system, it can distort how the team reads every later additive on press.

4. Respect the watchpoint, not only the headline benefit

2100 brings a film-wetting route. 3501 brings a broader anti-sticking and handling route. 3062 brings a direct printing-ink defoaming route. Those practical differences usually decide the better first route more than the additive family name alone.

5. Keep the first trial set small

For many waterborne lamination-ink buyers, one 2100 wetting route, one 3501 handling route, and one 3062 defoaming route teach more than an overloaded first screen filled with partially overlapping additives.

FAQ

Which additive should I screen first if a waterborne lamination ink still hesitates on film?

Usually 2100, because the supported route is built around printing-ink wetting with flexible addition timing and water-based compatibility.

When should 3501 move ahead of 2100?

3501 should move ahead when the ink already lays down directionally but the dried print face still blocks, drags, or handles poorly before lamination, rewinding, or other converting steps.

When does 3062 make more sense than the other two?

It makes more sense when foam, microbubbles, or air release still dominate the visible defect pattern and the team needs a printing-ink defoamer route rather than another surface-control trial.

Is this page the same as the broader waterborne flexographic or gravure pages?

No. Those pages answer wider process questions. This page is narrower and helps waterborne lamination-ink buyers decide whether the first bottleneck is film wetting, dried-print handling before lamination, or waterborne foam.

Does this page make lamination-bond or food-contact claims?

No. This page stays focused on additive-selection logic for waterborne lamination workflows. Any bond-strength, migration, compliance, or final structure qualification still needs separate formulation and regulatory review.

Next step

If your waterborne lamination project is stuck between film wetting, dried-print handling before lamination, and waterborne foam, stop treating them as the same additive request. Start with the real bottleneck first. That usually makes the next CHLUMICRYL® sample decision faster and more commercially useful.
