Explore our selection of commercial-grade UV curable prepolymers, developed to deliver outstanding curing kinetics, chemical resistance, and substrate adhesion.
Guangdong Ever Ray Environmental Material Co., Ltd., established in 2006, is a premier high-tech enterprise dedicated to the R&D, synthesis, and supply of advanced photopolymerizable chemicals.
To satisfy growing global demands and assure supply chain continuity, we maintain two separate modern manufacturing bases:
Our infrastructure integrates advanced DCS fully computerized controls with strict raw material screening. Supported by raw materials from trusted suppliers and strategic technical consultations with external photopolymer experts, we maintain precise batch-to-batch stability and optimize properties like monomer conversion rates and polymerization yields.
As global environmental standards tighten, the radiation curing industry is undergoing transitions in performance requirements and chemical compositions.
Traditional UV curing relies on reactive diluent monomers to adjust viscosity, which can contribute to volatile organic compounds (VOCs) and skin irritation hazards. Our technology roadmap prioritizes waterborne polyurethane acrylates (WPUs), using water as the primary viscosity modifier. This allows for zero-VOC formulations without compromising cross-linking density or adhesion profiles.
Sustainability is key to modern chemical manufacturing. Ever Ray is actively synthesizing oligomers based on bio-sourced polyols, functionalized vegetable oils, and renewably sourced diisocyanates. Our target is to increase the renewable carbon index of our polyurethane and polyester acrylates to over 40% within the next three years, reducing dependencies on fossil fuels.
Volumetric shrinkage during cure remains a common challenge with acrylic radicals. By modifying polymer backbones and developing hyperbranched polyester structures, our current synthesis pathway helps control volume shrinkage under 3%. This enables formulation of scratch-resistant coatings with high substrate adhesion on glass, metal, and plastic.
Different industries demand distinct physical and chemical characteristics from UV oligomers. Below is a summary of how Ever Ray addresses these performance profiles:
Key requirements: Scratch resistance, chemical resistance against domestic cleaners, fast line speed.
Solution: Epoxy acrylates combined with fast-reacting polyester acrylates like our 5502B. This provides hard surface finishes, low odor emissions during curing, and high production speeds on roller coating production lines.
Key requirements: Thermal cycling stability, non-cracking behavior, adhesion to low-energy surfaces (PC, ABS, treated PP).
Solution: Aliphatic polyurethane acrylates (PUA) and specialized modified aromatic resins (e.g. 7162, 7160). These systems help manage mechanical stress during cure, providing flexible, non-yellowing protection.
Key requirements: Pigment wetting, low-viscosity transfer in gravure/flexo, high speed cure, specialty effects.
Solution: Polyester and modified epoxy acrylates with high polar functional groups. Products like our 7317 support textured effects (snowflake/wrinkle finishes), while maintaining high pigment loading and suspension stability.
Key requirements: Peel strength, moisture resistance, flexible post-cure deformation.
Solution: Modified acrylates engineered for low shrinkage and high cross-linking. Our structural acrylates preserve dimensional integrity, providing stable bond lines between glass, plastic, and metal substrates.
Operating in the center of China’s chemical cluster in Guangdong, Ever Ray leverages local chemical supply chains to optimize manufacturing costs and product availability.
Direct proximity to key monomer, polyol, and isocyanate manufacturers in Southern China allows us to source feedstock materials efficiently, reducing supply disruptions and raw material cost volatility.
Our Yunfu and Jiangmen factories use DCS automated systems to monitor feed rates, pressure limits, and heating curves in real time, limiting human error and supporting consistent batch quality.
With dedicated warehouse facilities, hazardous chemical shipping licenses, and close proximity to major ports (Guangzhou, Shenzhen), we support fast shipping and flexible MOQ setups for global buyers.
Navigating global chemical regulations and product customization is critical for modern industrial chemical procurement. Here is how we support global sourcing requirements:
Our R&D team works directly with clients to adapt oligomer designs to regional curing equipment setups and seasonal climate variations. Whether adjusting high-temperature viscosity stability for Middle Eastern clients or low-viscosity flow profiles for European high-speed packaging lines, we customize molecular weights and monomer additions to meet specific application criteria.
We provide safety data sheets (SDS) following GHS standards, detailed certificates of analysis (COA), and technical datasheets (TDS) for every batch, simplifying incoming raw material quality checks.
Ever Ray monitors international chemical regulation updates to ensure product compliance across regional markets.
