High-performance formulations engineered to eliminate oxygen inhibition and accelerate curing
In the field of photo-polymerization, achieving a complete and rapid cure at the surface is one of the most critical challenges facing chemical formulation engineers. Atmospheric oxygen behaves as a powerful radical scavenger, interacting with initiating and propagating free radicals. This leads to the formation of stable, non-initiating peroxy radicals, resulting in incomplete polymerization, surface tackiness, and inferior mechanical properties.
Active amines (commonly functioning as amine synergists) are chemical compounds designed to mitigate this issue. Through hydrogen atom donation, they react with scavenging species to generate highly active carbon-centered radicals. These newly formed radicals react rapidly with monomeric double bonds, initiating polymer propagation and effectively overcoming the inhibitory pathway of oxygen.
“By integrating polymerizable amine moieties directly into oligomeric and monomeric networks, we minimize migration risks, reduce chemical odor, and enhance the overall E-E-A-T profile of modern UV coatings.”
Direct integration of manufacturing pipelines yields superior batch consistency, localized customized modifications, and regulatory compliance (REACH, TSCA). As global regulations tighten around residual monomer limits, manufacturers who design functionalized, high-molecular-weight amine oligomers provide the safety margins required by modern industrial end-users.
Mapping the transition from commodity monomers to high-performance, eco-friendly systems
Global regulatory bodies, including the EPA and ECHA, are continuously pushing to replace traditional solvent-borne formulations with high-solid, radiation-curable, and waterborne systems. Active amines play a vital role in reducing the viscosity of these green formulations without requiring volatile organic solvents.
Industrial printing presses, wood finishing workshops, and electronics packaging facilities demand line speeds exceeding 100 meters per minute. Formulators rely heavily on high-activity amine acrylates to meet these production cycle times while maintaining scratch, chemical, and mar resistance.
For food packaging and medical devices, migrateable low-molecular-weight photoinitiators and free amines pose biological hazards. The market is shifting from monomeric liquid amine synergists to polymeric or polymerizable active amines that anchor securely to the cured polymer matrix.

Tailoring amine solutions to specific manufacturing environments and processing conditions
In humid manufacturing regions, oxygen and moisture can slow down coating lines. Introducing low-viscosity, high-reactivity modified epoxy and polyurethane acrylates (such as our 6116 and 6118 series) ensures rapid surface curing, high surface hardness, and superior scratch resistance on wood veneer and fiberboards.
Plastics like ABS, PC, and PMMA require low curing temperatures to prevent heat distortion. Using highly functional polyurethane acrylate oligomers together with active amine synergists allows for low-temperature, low-energy UV LED curing, protecting sensitive electronics and delicate plastic casings.
In high-speed flexo and offset packaging print runs, thin ink layers are highly vulnerable to oxygen inhibition. Active amines are critical for dry-to-touch surface curing, maximizing print clarity, preventing ink transfer (blocking), and ensuring excellent adhesion to non-porous polymer films.
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 (water borne, aliphatic urethane, aromatic urethane), polyester acrylate, pure acrylate, and other special functional modified acrylate oligomers.
We operate two modern production bases: one is in Jiangmen, Guangdong, with a production area of about 10,000 square meters; the other is in Yunfu, Guangdong, with a production area of around 40,000 square meters. Complete with quality control, storage, and logistics supporting facilities, our annual production capacity exceeds 20,000 tons across more than 10 production lines.
To ensure strict quality control, our factories operate under the ISO9001 quality management system and the ISO14001 environmental management system, supported by a flexible, advanced, fully computerized DCS control system. Moreover, we select high-quality domestic and foreign raw materials, adopt advanced scientific management methods, and consult with domestic UV material experts to guarantee production safety and reliable product quality.
We hold more than 10 invention patents and practical utility patents. With over 15 dedicated technicians in our R&D department, we focus on delivering high reactivity, chemical resistance, and high gloss to formulations across a wide variety of applications, including wood coatings, plastics, inks, and adhesives. We supply custom formulations tailored to meet client demands—balancing physical functionality with cost-saving goals.
