Xianlin MEKO: A “Hubei Premium” Recognized Source for Anti-Skinning, Silane & Blocking Applications

If you formulate alkyd coatings, produce oxime-silane crosslinkers, or work with isocyanate-blocked polyurethane systems, Methyl Ethyl Ketoxime (MEKO) is likely already on your radar. And on this molecule, Hubei Xianlin Chemical is a source worth knowing.

What it is
MEKO (CAS 96-29-7) is a clear, colorless liquid with three core application lanes:

Anti-skinning agent for oil-based paints and coatings—alkyds, epoxy esters—preventing solid skin formation during storage while stabilizing viscosity. Typical dosage: 0.1–0.3%.

Raw material for oxime-silane crosslinkers: upstream of ketoxime-type silane curing agents used in one-component RTV silicone rubber.

Isocyanate blocking agent, widely used in polyurethane systems, including automotive electrodeposition coatings.

Why Xianlin?

The credential is officially stamped, and the capacity is real.

In May 2026, Xianlin’s MEKO was officially named to the third cohort of “Hubei Premium” —a recognition administered by the Hubei Brand Promotion Office, assessed on product standards and independent intellectual property. It is a third-party quality benchmark, not a self-declaration. The product is backed by Xianlin’s proprietary synthesis process, multiple invention patents, and a green production technology that has earned Hubei Provincial Science & Technology Progress awards.

On capacity, Xianlin operates 30,000 tonnes/year of MEKO production and is one of the world’s major MEKO suppliers. The company is a state-controlled national high-tech enterprise, holding national-level “Little Giant” (specialized and sophisticated) and “Manufacturing Single Champion” designations. For buyers, that means dealing with a plant that owns the production asset, the process patents, and the quality credential—not a trader managing batch risk.

Downstream, Xianlin’s MEKO feeds directly into its own ketoxime-silane crosslinker line (MOS/VOS). The chain stays inside one company, and traceability does not cross a corporate boundary.

Who it’s for

Alkyd/epoxy ester coating and offset ink producers (anti-skinning & viscosity stabilization)

Oxime-silane crosslinker and RTV silicone manufacturers (direct upstream sourcing)

Polyurethane and electrodeposition coating formulators (isocyanate blocking)

Procurement teams looking for a fine chemical supplier with an official quality credential
