Explore our premium grade UV-curable resins, formulated for scratch resistance, fast curing, and low shrinkage.
Established in 2006, Guangdong Ever Ray Environmental Material Co., Ltd. has evolved into a global leader in the R&D, manufacturing, and supply of premium oligomers for UV curable systems. We design, test, and scale advanced chemical structures—including epoxy acrylates, polyurethane acrylates (waterborne, aliphatic, and aromatic), polyester acrylates, pure acrylates, and custom functional monomers.
By working closely with formulations laboratories in electronics, automotive, footwear, and consumer goods packaging, we provide tailored chemistries that achieve rapid reaction kinetics, unmatched surface hardness, and minimal volumetric shrinkage. We balance aggressive technological advancement with eco-friendly engineering to support the next generation of industrial coatings and adhesives.
Industrial procurement departments faces multiple challenges: batch consistency, environmental restrictions, and demanding cure rates.
Conventional thermo-set epoxy resin systems require long bake cycles, bottlenecking production lines. Fast photo-curing resins offer sub-second polymerization, but can cause inner stress buildup and micro-cracking if poorly formulated.
High crosslink density in rapid acrylic and epoxy formulations often leads to significant shrinkage. This creates internal stress that weakens the bond to metal, glass, and plastic substrates.
Global supply chains must comply with dynamic environmental policies (RoHS, REACH, TSCA, and low VOC restrictions). Suppliers need to proactively reformulate their raw materials to remove tin, heavy metals, and toxic monomers.
Our tailored chemical designs solve complex application challenges in high-demand industrial sectors.
Products like our 73008 Low-Shrinkage Polyurethane Acrylate Resin provide reliable thermal cycling stability and high dielectric strength. They protect sensitive electronic components from moisture and mechanical stress.
The 72017A-8 Dual-Curing UV Resin is engineered for high elasticity and low shrinkage in SLA/DLP 3D printers, producing durable midsoles and functional elastomer components.
By combining hyperbranched acrylates (like our 4600 Resin) with epoxy acrylates, we deliver coatings for wood, metal, and plastic that offer high chemical resistance and resist yellowing.
To ensure reliable batch-to-batch consistency and secure global supply chains, Ever Ray operates two specialized production facilities in Guangdong province. Our plants are managed under strict ISO 9001 and ISO 14001 guidelines, supported by a fully computerized DCS (Distributed Control System) for precise batch control.
Jiangmen Plant (Guangdong): Spans 10,000 square meters, focused on high-precision specialty oligomers and rapid-response formulations.
Yunfu Plant (Guangdong): Spans 40,000 square meters, designed for high-volume synthesis and logistics storage, bringing our total annual capacity beyond 20,000 tons across 10+ automated production lines.
Our R&D department features a team of 15+ dedicated technicians and holds more than 10 utility and invention patents. We help clients optimize performance parameters while managing raw material costs.
An in-depth look at the curing kinetics and polymer chemistry that drive our high-performance resins.
The performance of a quick-curing UV resin is defined by its oligomer backbone. By modifying epoxy acrylate molecular chains, our researchers have introduced functional groups that improve adhesion and reduce yellowing.
During UV exposure, photoinitiators split into free radicals that attack the acrylate double bonds (C=C), triggering a rapid chain reaction. Our modified resins optimize this process, achieving high double-bond conversion rates under lower UV dosage, which minimizes uncured monomers.
For applications requiring flexibility and outdoor stability, we offer aliphatic polyurethane acrylates. These systems resist oxidation and environmental yellowing, making them ideal for automotive protective films and optical coatings.
| Oligomer Type | Key Benefit | Cure Speed |
|---|---|---|
| Epoxy Acrylate | High Hardness, Fast Cure | Very High (<1s) |
| Polyurethane Acrylate | Flexibility, UV Resistance | High (1-2s) |
| Polyester Acrylate | Low Viscosity, Pigment Wetting | Moderate (2-3s) |

Our materials comply with RoHS, REACH, and TSCA standards, ensuring seamless import and regulatory clearance across Europe, the Americas, and Southeast Asia.
We work directly with chemical blenders and industrial users, adjusting parameters like viscosity, flexibility, and curing speed to match your specific production line requirements.
We partner with leading global logistics providers and maintain secure storage bases in Yunfu, ensuring stable shipping times and protected cargo handling for ocean freight.
Expert answers to common questions about formulating and application of fast-curing photopolymer resins.
We optimize oligomer structure using hyperbranched monomers and custom-synthesized polyurethane acrylates (such as our 73008 grade). This maintains high chemical resistance while providing steric hindrance that limits volumetric shrinkage during polymerization.
Dual-curing resins (like 72017A-8) combine free-radical UV polymerization with secondary heat curing. The UV exposure cures the outer shape of the printed object, while the post-bake finishes the interior reaction, leading to improved mechanical properties.
We use high-purity aliphatic raw materials and avoid aromatic structures in our premium anti-yellowing oligomers. This prevents the formation of UV-absorbing quinoid chromophores, keeping coatings clear and colorless.
Yes, our R&D team designs oligomers like the 5502B Polyester Acrylate to minimize volatile residual monomers. This significantly reduces odor during and after the UV curing process.
