Premium functional acrylates formulated for industrial performance, adhesion, and rapid UV curing.
Polyester acrylate oligomers are a vital class of photopolymerizable materials, forming the structural foundation of modern ultraviolet (UV) and electron beam (EB) curable systems. Produced via the direct esterification of polyols and dicarboxylic acids, subsequently capped with acrylic acid, these oligomers present a highly versatile chemical backbone. This molecular versatility enables researchers to tailor physical qualities—such as viscosity, glass transition temperature (Tg), hardness, and molecular weight distribution—to fulfill exact application specs.
In high-speed processing environments like flexographic, offset, and gravure printing, polyester acrylates provide critical pigment wetting capabilities and rheology control. Their low molecular weight variants act as efficient reactive diluents, minimizing the reliance on volatile organic solvents (VOCs). Consequently, industries ranging from high-end electronics packaging to wood coatings leverage these oligomers to meet strict environmental demands while securing rapid throughput, scratch resistance, and robust chemical stability.
Multi-functional ester link design increases crosslink density rapidly under UV light radiation exposure, lowering energy consumption.
Formulated with precise backbone structures to enable excellent pigment wetting, smooth leveling, and minimal organic solvent usage.
Enhanced protection against thermal stress, solvents, and abrasion, ideal for harsh electronic and automotive coatings.
The global demand for high-purity UV-curable resins is expanding rapidly, driven by strict environmental mandates targeting VOC emissions and the push for faster manufacturing throughput. Industrial coaters, ink formulators, and packaging giants require high-volume manufacturing partners capable of delivering consistent batch-to-batch polymer compositions. As a reliable B2B supplier, our dual production bases are strategically located to maintain an uninterrupted supply chain across the Americas, Europe, and the Asia-Pacific region.
Technical buyers typically prioritize chemical metrics: acid value limits (crucial for maintaining formula shelf life), color indexes (measured on the APHA scale for clear topcoats), and shrinking percentages during polymerization. By utilizing state-of-the-art synthetic reactors, our facilities optimize polyester backbones to reduce curing shrinkage. This reduction addresses a primary challenge in industrial applications: substrate adhesion failure on glass, metals, and composite plastics.

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. Our extensive product portfolio includes epoxy acrylate, polyurethane acrylate (waterborne, aliphatic urethane, aromatic urethane), polyester acrylate, pure acrylate, and custom-modified functional acrylate oligomers designed for high-performance applications.
Equipped with more than 15 chemical technicians in our R&D division and holding over 10 invention and utility patents, we engineer raw materials that deliver high reactivity, excellent chemical resistance, and superior optical clarity. We focus on harmonizing technology and environmental protection, driving sustainable B2B chemical manufacturing to support a greener global footprint.
To support high-volume global procurement, we operate two production bases in Guangdong province. The first facility, located in Jiangmen, spans approximately 10,000 square meters. The second facility, situated in Yunfu, covers around 40,000 square meters. Combined, they feature advanced quality control labs, expansive warehousing, and dedicated logistics facilities. Our annual capacity exceeds 20,000 tons, distributed across more than 10 fully automated production lines.
Both production bases operate under the ISO9001 Quality Management System and the ISO14001 Environmental Management System. We run a flexible Distributed Control System (DCS) to monitor every step of the chemical reactions, ensuring batch consistency, safety, and operational transparency.
Polyester acrylates are engineered for a broad range of industrial applications, providing unique performance profiles across different substrates and curing systems.
