Water-Based Resins for Printing Ink Formulation
Ink formulators and converters making their own inks source a water based resin for printing ink that controls the trade-off between resolubility, drying, adhesion and film hardness. chemlinkai supplies acrylic, styrene-acrylic and polyurethane dispersions synthesized in-house, with polymer targets — Tg, acid value, particle size — adjustable to the print process and substrate you formulate for.
How the system works
A printing ink inherits its personality from the resin: resolubility in the cell, drying on the web, adhesion to the substrate, and hardness of the final film. Changing the resin changes all of these together, which is why resin selection is formulation, not purchasing.
We supply resin dispersions as raw materials with defined polymer parameters, plus the application knowledge to place them. You define the target: gravure or flexo, the substrate family, the drying budget and the end-use performance. We recommend the resin family and, where volumes justify it, tune the polymer within our platform — the same in-house synthesis that feeds our own finished inks.
- Acrylic, styrene-acrylic and PU dispersion families for ink formulation
- Polymer parameters (Tg, acid value, solids, particle size) stated per grade
- Resolubility and drying behavior characterized for gravure and flexo use
- Synthesis controlled in-house; grades adjustable to qualified volume
Why does a resin that works in one ink fail in another — and how do you de-risk the choice?
Resin performance is always relative to the system around it. The same dispersion that delivers clean resolubility with one pigment set can flocculate with another, and the Tg that gives the right block resistance on film can make an ink brittle on paper. Choosing a water based resin for printing ink on datasheet values alone misses these interactions, because datasheets state the polymer, not the ink.
We de-risk selection in two steps. First, a compatibility screen: the resin is tested against your pigment dispersion, additives and the solvents in your let-down. Second, a drawdown trial on your substrate with the drying and rubbing targets you specify. You receive the resin with a documented recommendation, not a promise that it will behave in every formula.
Representative polymer parameters
Family-wide guidance ranges across our dispersion platform. Grade-specific values are confirmed per sample and batch TDS.
| Parameter | Representative range | Remark |
|---|---|---|
| Solids content | 35 – 45 % | Depends on polymer family and grade |
| Glass transition (Tg) | −10 to +40 °C across the platform | Selected for hardness vs. flexibility balance |
| Acid value (polymer) | Grade-specific — stated per TDS | Drives resolubility and water response |
| pH | 7.0 – 9.0 | Stability window of the dispersion |
| Viscosity (Brookfield) | 50 – 2000 mPa·s across grades | Measured per supplied sample |
| Particle size | Method-specific — stated per grade | Affects film clarity and rheology |
| Storage stability | 6 months sealed, 5 – 35 °C | Avoid freezing; handling guide supplied |

How the resin platform reaches your formulation
Resins are synthesized in-house, formulated into ink systems, verified in application, then released with batch QC — the same chain whether you buy the finished ink or the resin to formulate your own.
Resin supply, two ways to start
Depending on your model — raw-material buyer or system buyer — both routes start from the same in-house polymer platform.
Waterborne Resins & Surface Treatment
Resin platforms and surface treatment systems across inks, coatings and adhesives — with formulation support for your own recipes.

Ink resin supply — common questions
Direct answers for ink formulators, R&D managers and purchasing teams.
Do you supply resins as raw materials or only finished inks?
Both, from the same synthesis platform. Raw-material supply follows a qualification process: sample, compatibility screen with your pigments, then volume terms. Finished inks are the route when you prefer a full system.
Can you adjust a polymer for our specific target?
Where the volume justifies development, we tune parameters such as Tg, acid value and particle size within the platform. The adjustment is documented and released with its own TDS.
What information do you need to recommend a starting resin?
Process (gravure or flexo), substrate, drying budget, and the end-use targets for adhesion, hardness and resolubility. With those, we can shortlist within one exchange.
What are the minimum order quantities for resin supply?
Sample quantities are provided for qualification. Production MOQ depends on the grade and packaging; we confirm it in the commercial proposal before you commit.
How is batch-to-batch consistency controlled?
Each synthesis batch is released against the stated polymer parameters — solids, pH, viscosity, particle size — with retained samples. Batch records support your own incoming QC.
Documentation
Documents are released per grade and application after final verification.
Documents marked “pending” are released after final verification — request the current version through the form and we will send it with the applicable scope.
