Engineered for precise rheological control, sub-second radical crosslinking, and substrate adhesion across industrial coatings, precision electronic adhesives, and advanced 3D stereolithography.
Balancing conversion rates, volumetric shrinkage, and mechanical toughness through precision isocyanate selection, polyol backbone synthesis, and hyperbranched functionality engineering.
Aliphatic polyurethane acrylates (IPDI, HDI-based) provide non-yellowing performance, weatherability (ΔE < 1.5 after 1000h QUV testing), and elongation exceeding 120%. Aromatic variants (TDI, MDI-based) deliver surface hardness (≥3H), superior chemical and solvent resistance, and rapid radical polymerization for interior high-wear substrates.
Dendritic oligomer design decouples resin viscosity from crosslink density. By synthesizing 6 to 15 functional terminal acrylic double bonds onto a globular multi-core structure, formulators achieve pencil hardness >4H, scratch resistance, and low shrinkage (<4.5%), without requiring excessive reactive diluents.
Self-emulsifying waterborne polyurethane acrylates (WPUA) integrate hydrophilic ionic internal groups (DMPA/DMBA) alongside curable unsaturated chains. This eliminates petroleum solvents, minimizes film thickness down to 5μm, prevents skin irritation, and aligns with European Decopaint & REACH directives.

Operating from our Yunfu chemical manufacturing cluster in Guangdong, Guangdong Ever Ray Environmental Material Co., Ltd. provides scale, raw-material control, and consistent quality.
Our 10+ synthetic production lines leverage PLC-monitored exothermic batch reactors with automated dosing of isocyanates, acrylic acids, catalysts, and free-radical inhibitors. Real-time temperature control within ±0.5°C prevents unwanted thermal prepolymer gelation and keeps batch-to-batch acid values (≤2.0 mg KOH/g) stable.
Every commercial production drum undergoes inspection: Gel Permeation Chromatography (GPC) for Mw and polydispersity (PDI), Fourier-Transform Infrared Spectroscopy (FTIR) verifying NCO consumption (<0.1% residual free isocyanate), cone-and-plate rheology checks, and Gardner color metrics (≤1.0 for aliphatic clears).
By anchoring production in the Greater Bay Area chemical hub, Ever Ray maintains direct pipeline and bulk storage connections for critical upstream feedstocks—including acrylic acid, polyols, BPA epoxies, and isocyanates (HDI, IPDI, TDI)—shielding international buyers from seasonal volatility.
Turnkey chemical export compliance, documentation, and tailored logistical pipelines across North America, the European Union, Southeast Asia, and the Middle East.
Full dossiers covering European Union REACH registrations, SVHC compliance certificates, TSCA inventory status for North America, and multi-language Globally Harmonized System (GHS) Safety Data Sheets (SDS) are provided for each shipment.
Packaged in sealed 20kg UN-certified fluorinated plastic drums, 200kg heavy-duty steel drums, or 1000kg composite IBC totes protected with anti-static barriers and nitrogen headspaces to prevent moisture intrusion and premature radical polymerization during transoceanic shipping.
Formulators receive 500g to 2kg evaluation samples matched with baseline formulation recommendations. Our application center replicates customer UV/LED lamp spectra (Mercury arc, 365nm, 385nm, 395nm, 405nm) and substrate parameters prior to full scale-up.
Insights from our senior material scientists and global supply-chain directors.
Surface oxygen inhibition under low-energy LED light often results in residual surface tack. We address this by incorporating amino acrylate co-initiators or reactive amine synergists alongside high-reactivity modified epoxy or hyperbranched acrylates. These donate alpha-hydrogen radicals to scavenge peroxy radicals, accelerating surface tack-free times.
Yes. Simply introducing mono-functional monomers lowers viscosity but often compromises glass transition temperature (Tg) and modulus. We optimize the polyol backbone length and introduce hyperbranched acrylic architectures, lowering viscosity while maintaining crosslink density and tensile strength.
We welcome physical and third-party ISO audits at our Yunfu chemical facility. Lab samples (500g–1kg) ship internationally within 3 to 5 business days via air freight. Commercial orders of standard grades ship within 10 to 14 days, supported by complete lot-specific Certificates of Analysis (COA).
Adhesion on inorganic substrates often deteriorates when water penetrates the polymer-substrate interface. Our specialized functional urethane and epoxy grades incorporate carboxyl and phosphate adhesion-promoting moieties that establish covalent and coordination bonds with silanol and metallic hydroxyl groups, passing 2-hour boiling-water immersion tests.
