Engineered for high adhesion, chemical resistance, and optical clarity under tough physical and environmental conditions.
Romania has rapidly solidified its position as one of Central and Eastern Europe's key industrial manufacturing epicenters. With a booming automotive industry anchored in regions like Pitești and Craiova, a prominent wood processing and furniture-making tradition in Transylvania (Cluj, Maramureș, and Brașov), and an expanding tech-packaging sector in Bucharest, the country's manufacturers demand highly durable, efficient raw materials.
Aliphatic Polyurethane Acrylate Oligomers are critical components in formulating modern UV-curable industrial coatings, high-precision plastics, smart adhesives, and print varnishes. Unlike aromatic structures, aliphatic chemistry prevents photochemical breakdown and yellowing caused by UV light. This makes our oligomers the top choice for external automotive body parts, high-end indoor and outdoor wooden furniture, and packaging materials that must meet strict EU safety and durability criteria.
Formulated to survive Romania’s sharp seasonal temperature shifts without cracking or peeling.
Fully traceable raw materials conforming to stringent European chemical regulation systems.
How the shift toward zero-VOC limits, high line-speed curing, and dual-cure mechanisms changes global supply patterns.
European environmental mandates are driving industrial coating formulations away from solvent-based systems. Our polyurethane acrylates facilitate 100% solid, zero-VOC formulations that drastically reduce carbon footprints.
Modern assembly lines demand curing cycles measured in fractions of a second. High acrylic double-bond density ensures ultra-fast curing kinetics under mercury arc or LED-UV arrays.
For complex three-dimensional geometries, shadowing can prevent complete UV light exposure. Our dual-cure oligomers integrate secondary thermal mechanisms to ensure complete curing in shadowed areas.
Established in 2006, Ever Ray is a premier high-tech chemical manufacturer focusing on oligomers for UV-curable resins, including epoxy, polyurethane, and pure acrylates. With decades of targeted research, we select elite domestic and foreign raw materials and manage synthesis using advanced, fully computerized DCS controls.

A technical guide for industrial paint chemists and formulators across Eastern Europe.
In formulation chemistry, the key differentiator between aliphatic and aromatic polyurethane acrylates lies in the chemical structure of the raw diisocyanates. Aromatic types, typically synthesized using toluene diisocyanate (TDI) or methylene diphenyl diisocyanate (MDI), contain highly reactive benzene rings. Under sunlight or high-energy UV exposure, these rings undergo photo-oxidative degradation, rearranging into chromophoric quinoid structures. This process causes yellowing, loss of gloss, and micro-cracking.
Aliphatic polyurethane acrylates, utilizing hexamethylene diisocyanate (HDI) or isophorone diisocyanate (IPDI), completely bypass this pathway. Formulations featuring HDI or IPDI maintain optical clarity, presenting negligible color shifts (ΔE < 1.0 after 1000 hours of QUV accelerated weathering). This resistance makes them essential for high-end clear coats on wood furniture and automotive plastics.
Formulators often struggle to balance scratch resistance (high glass transition temperature, Tg) and mechanical flexibility (elongation at break). Ever Ray addresses this by designing oligomer backbones with balanced soft polyether or polyester segments coupled with rigid urethane links.

Technical guidance on compliance, logistics, and material behavior for purchasing managers and chemists in Romania.
Yes. Compliance with EU chemical regulations is essential for exporting to Romania. We provide full support for REACH registration, sharing chemical makeup data and safety sheets (SDS) formatted to European regulations. We also partner with EU OR (Only Representative) agencies to ensure smooth clearance through customs at ports like Constanța.
For standard FCL (Full Container Load) shipments from Shenzhen or Nansha port to the Port of Constanța, the sea shipping time is typically 30 to 38 days. Standard order processing and manufacturing take 7 to 14 days, depending on batch customization. For urgent testing, we ship air-freight samples (1kg - 5kg) via DHL or FedEx, which arrive in Bucharest within 5-7 business days.
Romanian winters can see temperatures drop below -20°C. Standard aromatic coatings may become brittle and crack under these conditions. Our aliphatic polyurethane acrylates (such as the 7253A-5 and 72203A series) are designed with a low glass transition temperature (Tg) and flexible polyether/polycarbonate chains. This ensures the cured film maintains its elasticity and adhesion down to -30°C without cracking.
Yes. Our R&D department can adjust viscosity levels by modifying the oligomer backbone or pre-diluting products with monomers like IBOA, TMPTA, or TPGDA to match your application setup (such as roller coating, spray gun, or slot-die extrusion). Contact our technical support team with your targeted viscosity range, cure speed, and substrate details for a customized formulation.
All UV-curable materials should be stored in their original sealed containers in dry, well-ventilated spaces, out of direct sunlight and UV radiation. Keep storage temperatures between 5°C and 30°C. Under these conditions, our oligomers have a guaranteed shelf-life of 12 months from the manufacture date.
