High-Quality Glue & Epoxy Factories: Industrial UV-Curable Resins & Oligomers

Precision Engineering, Scalable Manufacturing, and Eco-Conscious Advanced Polymer Chemistry for Global Enterprise Demands.

About Guangdong Ever Ray

Established in 2006, Guangdong Ever Ray Environmental Material Co., Ltd. is a nationally recognized high-tech enterprise at the forefront of researching, developing, and manufacturing high-performance oligomers for UV curable resin. Our comprehensive synthesis platform encompasses epoxy acrylates, polyurethane acrylates (waterborne, aliphatic, and aromatic urethane), polyester acrylates, pure acrylates, and a diverse spectrum of specialized custom-modified acrylate oligomers tailored for extreme operating environments.

By leveraging advanced macromolecular engineering techniques, we build materials that resolve classic formulation compromises—such as trade-offs between rapid curing speed, low volumetric shrinkage, and strong adhesion profiles. Over the past two decades, we have evolved from a regional chemical supplier into a trusted global raw material partner for industry leaders in precision electronics, high-end wood coatings, packaging offset printing, and high-performance adhesives.

With an unyielding commitment to eco-conscious chemistry, we continually develop low-VOC, solvent-free, and bio-derived curing oligomers that allow modern production processes to reduce their environmental footprint while boosting system efficiency.

Production Infrastructure & Quality Management

Operating out of two state-of-the-art manufacturing hubs in Guangdong, China, Ever Ray delivers unmatched supply chain security and volume scalability:

  • Jiangmen Production Base: Over 10,000 square meters of specialized development space optimized for custom resin synthesis and pilot-run validation.
  • Yunfu Production Base: Spanning 40,000 square meters of advanced manufacturing facilities, equipped with a centralized logistics network and mass storage units.

Our combined annual capacity exceeds 20,000 metric tons across more than 10 highly automated production lines. To guarantee uncompromising batch-to-batch consistency, both sites operate under strict ISO9001 Quality Management and ISO14001 Environmental Management Systems. The heart of our production utilizes a fully integrated DCS (Distributed Control System). This digital, computerized infrastructure monitors real-time pressure, temperature, and feeding parameters, eliminating human error and ensuring stable polymer distribution across all batches.

Technology Roadmap & Future Outlook

Pioneering high-density crosslinking and environmentally sustainable polymers for next-generation material specs.

As the international industry pivots away from traditional solvent-borne systems to curb VOC emissions, the demand for fast-curing, solventless UV/EB (Electron Beam) curing systems has accelerated. Ever Ray's R&D department, comprised of 15+ in-house formulation chemists guided by senior academic polymer experts, actively designs oligomers to meet these evolving targets:

  • Bio-Based Carbon Replacements: Integrating renewable monomers derived from plant starches and seed oils to yield sustainable epoxy acrylates without compromising physical hardness or yellowing resistance.
  • Waterborne UV Technology: Expanding our range of waterborne polyurethane acrylates (PUDs) for wood coatings, giving formulators excellent viscosity management without relying on reactive diluents.
  • Hyperbranched Architecture: Developing next-gen oligomers that offer exceptionally low viscosities but retain high functionality, resolving printability issues in high-speed digital UV inkjet systems.
  • Dual-Curing Systems: Formulating specialized oligomers that incorporate moisture-cure or thermal-cure components to ensure uniform curing in deep shadow areas of complex 3D components.

Our technological pursuit aligns science with environmental stewardship, creating a future where high performance and sustainable operations coexist seamlessly.

Macro Industry Solutions

Providing specialized properties designed to solve substrate-specific adhesion and protection challenges.

Packaging & Offset Inks

High pigment compatibility and rapid cure responses under low UV light intensities. Our polyester acrylates exhibit high ink-water balances, making them excellent candidates for commercial high-speed offset print lines.

Wood Coatings

Optimum scratch resistance, chemical resistance, and high optical clarity. Aliphatic polyurethane acrylates (such as our 7200-1) provide superior UV yellowing resistance for exterior wood panels and premium indoor furniture.

Plastics & Vacuum Metallizing

Excellent adhesion to difficult polymer substrates (ABS, PC, treated PP). Our specialized oligomers prevent shrinking during high-speed vacuum plating, preserving high-gloss finishes without surface cracking.

Localization Support, Compliance & Regulatory Vetting

To successfully integrate chemical imports into international manufacturing workflows, procurement and safety teams require strict compliance assurances. At Ever Ray, compliance is a core pillar of our supply operations:

  • Global Registries: We verify chemical substance compliance, ensuring our products line up with REACH (Europe), RoHS/WEEE directives, and EPA requirements where applicable.
  • Safety & Logistical Documentation: Every shipment is backed by compliant Safety Data Sheets (SDS), certificates of analysis (COA), and customs-clearance documentation that simplifies import steps.
  • Technical Support: From optimizing curing speeds on your production lines to adjusting resin viscosity for regional humidity ranges, our engineers work directly with your team. We help adapt polymer properties to resolve specific processing challenges.

Procurement Vetting Best Practices

When sourcing UV curable resins globally, verifying raw material performance is vital to maintaining final product consistency. Formulators should prioritize:

  1. Viscosity Window Specification: Confirming optimal operating temperature profiles to prevent substrate wetting issues.
  2. Double-Bond Conversion Rate: Verifying post-curing performance to eliminate migration risks in packaging inks.
  3. Cure Shrinkage Ratios: Selecting modified epoxy or polyurethane acrylates that control physical shrinkage, preventing substrate warping.
  4. Residual Odor Evaluation: Specifying low-odor oligomers for indoor woodwork, electronics, and consumer cosmetics packaging.

Expert Formulation FAQ: Industrial UV Resins

Direct technical answers from Ever Ray's laboratory team to resolve common formulation and performance issues.

What defines the primary structural differences between aliphatic and aromatic polyurethane acrylates?
Aliphatic polyurethane acrylates (such as our 7200-1) are synthesized using non-aromatic isocyanates. They offer superior weathering resistance, long-term non-yellowing characteristics, and high outdoor durability, making them ideal for exterior wood and automotive topcoats. Aromatic polyurethane acrylates utilize aromatic structures, which deliver excellent scratch resistance, high tensile strength, and faster cure rates, making them suitable for interior substrates and cost-effective plastics.
How does Ever Ray manage raw material sourcing to ensure stable oligomer performance?
We partner with leading chemical suppliers globally and subject all incoming raw materials to strict purity and composition testing. By combining quality controls with our automated DCS computerized system, we keep batch-to-batch variation minimal, ensuring that our products meet precise technical specifications.
Which oligomer structures are recommended for reducing volumetric shrinkage on plastics?
Modified epoxy acrylates with lower ester densities and higher molecular weights help reduce curing shrinkage. Additionally, incorporating high-molecular-weight polyester acrylates or specialized urethane acrylates helps distribute curing stress, preventing warping and ensuring excellent adhesion to plastic substrates.
What makes polyester acrylates suitable for high-speed offset inks?
Polyester acrylates provide excellent pigment wetting capabilities, which allow for high color loading. They also offer a balanced lithographic performance, ensuring that high-speed printing presses can maintain ink-water stability, minimize misting, and dry rapidly under UV curing lamps.
