Premium selection of UV-curable prepolymers, flexible resins, and low-shrinkage oligomers designed for high-end optical varnishes, plastics, and structural adhesive formulations.
An analytical evaluation of industrial demand shift, environmental regulations, and critical parameter optimization for procurement directors.
Global regulatory architectures including EU's REACH, EPA rules in North America, and VOC emission directives in Asia are aggressively phasing out solvent-borne polyurethane systems. Procurement plans must pivot to radiation-curable (UV/LED-UV) and waterborne polyurethane acrylate systems to satisfy ecological compliance without sacrificing structural integrity.
Inconsistent raw material precursors (like specific diisocyanates and acrylate monomers) create massive supply risks. Procurement managers require vertically integrated chemical partners like Guangdong Ever Ray that command substantial annual capacities (>20,000 tons) to ensure structural price stability and consistent chemical purity index.
Unlike standard off-the-shelf consumer coatings, industrial-grade UV oligomer selection demands deep alignment on technical properties. Key parameters include glass transition temperature (Tg), viscosity profile under shear stress, shrinkage rates upon curing, conversion kinetics, crosslinking density, and substrate-level adhesive polar interactions.
Translating advanced photochemistry into tangible performance across heavy industries, high-speed automated packaging, and additive manufacturing.
The global consumer electronics sector demands high mechanical resistance combined with premium haptic properties. Products like Polycarbonate Acrylate 72203A are engineered to supply soft-touch characteristics while offering resilient scratch and rub resistance on ABS, polycarbonate (PC), and PMMA housings.
For modern printing systems, curing speed and low migration profiles are absolute requirements. Our 61003A LED-UV Packaging Resin enables rapid cure under narrow-spectrum LED-UV light bars. This dramatically reduces thermal stress on flexible plastic films, saving energy while fully meeting migration limits for high-end consumer packaging.
Traditional 3D resins suffer from excessive shrinkage and brittleness. Our specialized 72017 Photo-Thermal Dual-Curing Polyurethane Acrylate Resin solves this by integrating a primary UV radical polymerizing system with a secondary thermal curing network. This double-cure design delivers high toughness and structural integrity for industrial prototyping and functional end-use parts like footwear.

Guangdong Ever Ray Environmental Material Co., Ltd., established in 2006, is a high-tech enterprise focusing on the R&D and manufacturing of oligomers for UV curable resin such as epoxy acrylate, polyurethane acrylate (waterborne, aliphatic urethane, aromatic urethane), polyester acrylate, pure acrylate and other special functional modify acrylate oligomers.
We have more than 10 invention patents and practical patents. With more than 15 technicians in our R&D department, we provide high reactivity, chemical resistance, and high gloss to formulations for a wide variety of applications, including wood coatings, plastic, inks, adhesives, etc. We supply different formulations for customers to meet their requests not only from the product's functional capability but also from the cost-saving aspect. We focus on technology and environmental protection coexisting in harmony, firmly taking science and technology as our driving force in our future development, and continuing to pursue excellence and keep a sustainable green living environment in our daily life.
We operate two advanced production bases: one in Jiangmen, Guangdong, with a production area of about 10,000 square meters, and another in Yunfu, Guangdong, covering around 40,000 square meters. Both facilities feature quality control, storage, and logistics supporting equipment. The annual production capacity is more than 20,000 tons across more than 10 production lines.
To ensure strict quality control, the factory operates under the ISO9001 quality management system and ISO14001 environmental management system, coupled with a flexible, advanced DCS fully computerized control system. Moreover, we select high-quality domestic and foreign raw materials, adopt advanced scientific management methods, and consult domestic UV material experts for guidance to ensure production safety and product quality stability.
Tracking the structural shift of polyurethane coatings toward bio-based feedstocks, low-energy cure profiles, and smart functionality.
To reduce petroleum dependence, Ever Ray's chemical laboratory is synthesizing polyurethane acrylate (PUA) prepolymers from bio-derived polyols (sourced from castor oil, soybean oil, and organic succinic acids). This roadmap aims to achieve a bio-content index of over 40% while preserving the mechanical properties of aliphatic systems.
In three-dimensional components, complex geometry often blocks direct ultraviolet light path. The integration of secondary chemical curing mechanisms (like thermal condensation, hydroxyl-isocyanate crosslinking, or moisture curing) alongside fast photo-curing ensures zero uncured resin residue in hard-to-reach shadowed areas.
The future of polyurethane coating focuses on active material responsiveness. Incorporating smart polyurethane acrylate oligomers allows clear coats to reflow when exposed to local thermal stimulation. This heals superficial micro-scratches on automotive surfaces, protective displays, and high-wear consumer items.
