Chemistry we control
Resins are synthesized in-house, so performance is managed from polymer design to the finished ink, coating or adhesive — not passed through third parties.
chemlinkai develops integrated waterborne systems for printing, coating and bonding: from in-house resin synthesis and color development to application testing and on-press support. Start from your substrate and process — we match the chemistry to the line.

Choose the material you run, the process you print or coat with, or your industry. Every route leads to the ink, coating, adhesive or resin system that fits.
Select a substrate, process or industry to see the matching system.
We solve production problems on real substrates and lines — not with an endless product shelf. Start where you work.
Water-based inks, pigment concentrates, primers and functional coatings for decorative paper, PU paper and PVC / PP / PET decorative films — formulated for the lamination, heat and aging steps that follow printing.
Water-based gravure and flexographic inks, varnishes and solvent-free laminating adhesives for packaging structures — with the drying, bond and residual-solvent behavior your line specifies.
Water-based resin platforms for synthetic leather, inks, coatings and adhesives, plus surface treatment systems — built on chemistry we synthesize and control ourselves.
Water-based baking and protective coatings for metal, glass, automotive interiors and industrial parts — entered with documented scope and application testing.
Four differences that matter when your line, your quality standard and your delivery date are on the table.
Resins are synthesized in-house, so performance is managed from polymer design to the finished ink, coating or adhesive — not passed through third parties.
Ink, varnish, coating, adhesive, color and equipment support are treated as one system for your substrate and process — fewer compatibility surprises on the line.
Lab comparison, sample matching and on-press trials come before volume supply. We validate on your substrate, under your conditions.
Four manufacturing bases and a Hangzhou R&D institute support batch stability, color management and responsive technical service. As of September 2026.
Pick the failure you are fighting — every entry leads to the diagnostic route and the system we would start from.
Adhesion loss in water-based systems usually follows a pattern: surface energy, contamination, then binder and primer selection. We screen in that order and benchmark against your release requirements.
Drying is a system property — resin glass transition, solvent package and coating weight interact with your oven capacity. A formulation review plus a drying curve test finds the headroom.
Foam and microfoam in water-based gravure and flexo are managed at the formulation level — surfactant balance, resin selection and circulation conditions.
Color starts at pigment dispersion and ends in measurement discipline. We support strength targets, dispersion quality and color management on your press.
Bond strength depends on the adhesive, the film surfaces and the curing schedule. We test under your structure, temperature and aging conditions.
Send a sample of what you run today plus your substrate. We benchmark our system against your current material and report the difference — before any commitment.
Every engagement follows the same controlled path, so results are comparable and decisions are evidence-based.
Substrate, process, machine speed, current material, the problem you want to solve.
Our application lab selects and prepares the candidate system against your stated targets.
You run our sample — on your substrate, under your conditions — with agreed test methods.
We tune the formulation from trial feedback, then set up batch supply with QC and traceability.
Five families cover the converting and coating chain. Each family page links to substrates, processes and the verification path before supply.
