1. Company Profile Brief

Weicheng Advanced Material (Shandong) Co., Ltd is a professional specialized manufacturer of high-purity bifunctional acrylic monomers and functional polymer materials, with independent full-process production lines for Glycidyl Methacrylate (GMA) and Poly(glycidyl methacrylate) (PGMA).We adopt proprietary low-temperature two-step synthesis + multi-stage ultra-high vacuum continuous rectification technology, fully nitrogen-sealed closed production and DCS automatic control system, breaking the purity ceiling of domestic conventional GMA, and stably outperforming most domestic manufacturers and imported Japanese/Korean grades in purity, impurity control and thermal stability.We support stable mass supply, customized technical grades, complete global export compliance documents and one-stop technical after-sales service for clients across Southeast Asia, Europe and America.

3. Core Competitive Advantages of Weicheng GMA

1. Ultra-high purity benchmarkOur standard grade purity ≥99.85%, superior grade reaches 99.9%; far higher than domestic common 97.0%–99.0% and imported mainstream 99.2%–99.5%. Ultra-low ECH residual, dimer, moisture and acid value, no peculiar odor under 85°C high-temperature aging test, effectively avoid resin yellowing and volatile irritation.

2. Source-controlled low impurity designLow-temperature segmented reaction reduces side products by over 70%; multi-stage countercurrent water washing + ion exchange deep desalting removes salt and metal ion residues; high-vacuum low-temperature rectification prevents thermal cracking of GMA.

3. Stable batch consistencyFull-line nitrogen protection + real-time online GC monitoring; unqualified distillate automatically refluxes for re-rectification, tiny batch fluctuation guaranteed for continuous customer production.

4. Dual functional high reactivitySimultaneously carries polymerizable methacrylate double bond and reactive epoxy ring; flexible copolymerization & ring-opening crosslinking reaction with carboxylic acid, amine, hydroxyl and thiol groups, greatly improving coating adhesion, weather resistance and polymer interfacial compatibility.

5. Complete global export complianceFull set of documents including COA, TDS, MSDS, REACH registration materials, packaging test reports; fully compliant with EU PPWR packaging classification declaration rules, support sea/land container bulk shipment.

5. Wide Industrial Applications

• Powder coating polyester resin (largest consumption field)Epoxy groups crosslink with carboxyl polyester to enhance metal adhesion, water boiling resistance and outdoor weatherability, matching automotive parts, aluminum profile and home appliance powder coating manufacturers in Thailand & Southeast Asia.

• UV curable resin, automotive OEM & industrial inkProduce high-gloss, chemical-resistant acrylic coatings for auto body, coil coating, printing ink and wood paint.

• Polyolefin compatibilizer & plastic modifierRaw material for E-GMA graft monomer, improve interfacial bonding of PP/PE with PA, PET, engineering plastic alloys, widely used in auto plastic parts.

• Electronic structural adhesive & sealantEpoxy acrylic UV adhesive for electronic assembly, deliver high bonding strength to plastic, metal and glass substrates.

• PGMA precursor raw materialHigh-purity GMA ensures narrow molecular weight distribution, stable epoxy equivalent and low residual monomer for adsorption media, bioseparation carrier and surface functional polymer PGMA.
