Water-based resins: the polymer platform behind inks, coatings and synthetic leather.
chemlinkai synthesizes its own waterborne resins — acrylic-type series for printing inks and varnishes, and waterborne polyurethane series for synthetic leather and related coating work. Finished systems are formulated from these polymers, which is why ink, coating and adhesive behavior can be tuned at the polymer level.
Who this family serves
Resins are supplied in two ways: as the internal platform for our finished inks, coatings and adhesives, and as intermediates to formulators who build their own systems and need a polymer partner.
Series are kept intentionally separated by end use, because the polymer properties that matter — hardness, flexibility, pigment wetting, water resistance — are different for a printing ink, a varnish and a synthetic leather coat.
- Acrylic-type resins as binders for water-based gravure and flexo printing inks
- Resin series for overprint varnishes and clear coatings
- Waterborne polyurethane series for synthetic leather surface and tie coats
- Custom polymer development against a defined target profile
Resin series and typical ranges
Representative values across the series; each delivered grade is defined by its batch TDS.
| Resin series | Representative range | Remark |
|---|---|---|
| Series A — acrylic resins for printing inks | Solids 40-48 %; pH 7.5-9.5; viscosity class per grade | Binder for water-based gravure and flexo inks; pigment wetting and resolubility are checked in ink trials. |
| Series B — acrylic resins for varnishes | Solids 35-45 %; pH 7.5-9.0 | For overprint varnishes; gloss build and water resistance screened on target substrates. |
| Series C — waterborne polyurethane for synthetic leather | Solids 30-40 %; hardness and flexibility balanced per grade | Surface and tie coats for synthetic leather; hand feel and water resistance validated on your coating line. |
| Series D — development hybrids for coating topcoats | Range defined per development brief | Hybrid polymers for demanding topcoat requirements; representative data shared per project. |
| Series E — anchoring resins and primers for film | Solids 25-35 %; pH 7.5-8.5 | Used where adhesion on PP / PET needs an anchor layer before ink or topcoat. |
| Series F — custom resin synthesis | Target profile agreed in the development brief | Synthesis to your specification under a scoped agreement; series names to be finalized. |
Representative ranges as of September 2026; series names to be finalized and batch TDS issued per delivery — always verify against the batch TDS and COA.

Resin series feed both our own formulations and yours.
Resin questions
Can I buy resin from you to formulate my own ink?
Yes. Resin intermediates are supplied to formulators with application guidance and the same batch documentation as finished systems. Tell us your ink type, pigments and target performance, and we will point you to the starting series.
Acrylic or polyurethane — which should my ink be based on?
It depends on the balance you need: acrylic series generally bring hardness, pigment wetting and resolubility at a lower cost position, while polyurethane series bring toughness, flexibility and adhesion to difficult substrates. Hybrid development sits between the two when neither alone meets the spec.
What makes a resin suitable for synthetic leather?
The resin has to deliver the coating properties the finished material is sold on: hand feel, flexibility, water resistance and adhesion to the base fabric or nonwoven. Series C is screened against those four properties on your coating line before supply.
Do you develop custom resins?
Yes, under a scoped development agreement. We agree the target profile, the test methods and the milestones first; the polymer is then synthesized in-house and iterated against your samples. Series naming and documentation are finalized at the end of development.
How do I verify a resin before scaling up?
Start with a laboratory drawdown or coating on your substrate, then a pilot trial under your process conditions. Representative data and the batch TDS frame the comparison; acceptance criteria are agreed before the pilot, not after.
Resin documentation
What we publish today, and what stays marked pending until verified.
Documents marked “pending” are released after final verification — request the current version through the form and we will send it with the applicable scope.
Describe the polymer you need to build on.
End use, substrate, application method and the property that matters most. We map it to the platform — or scope a development project.
