What is the difference between aliphatic and aromatic polyurethane acrylate oligomers?

Aliphatic polyurethane acrylates are built on aliphatic isocyanates, so they resist yellowing under sunlight and are preferred for clear topcoats, 3C plastic coatings, nail gel and outdoor parts. Aromatic polyurethane acrylates offer toughness, abrasion resistance and cost efficiency, but tend to yellow on UV exposure, so they are best for pigmented or indoor applications such as wood and floor coatings.

Which oligomer should I choose for a UV wood or floor coating?

Epoxy acrylates are commonly used for sealers and sanding primers thanks to fast cure, hardness and good sandability. Topcoats usually combine epoxy or hyperbranched acrylates for scratch resistance with aromatic or aliphatic polyurethane acrylates for flexibility and abrasion resistance. Waterborne polyurethane acrylates are used when low VOC and low film-build are required.

Can Ever Ray develop a custom UV resin for my formulation?

Yes. Our R&D team adjusts backbone chemistry, functionality, viscosity and diluent package to meet target performance such as adhesion on difficult substrates, yellowing resistance, flexibility or cure speed. Share your substrate, curing equipment and performance targets through the contact page to start a development project.

What does an amino acrylate or active amine do in a UV formulation?

Amino acrylates and active amines act as synergists for Type II photoinitiators such as benzophenone or thioxanthones. They donate hydrogen to generate initiating radicals and help counter oxygen inhibition, which improves surface cure and line speed, especially in thin ink and overprint varnish films.

Do you provide technical data sheets and safety data sheets for export orders?

Yes. Technical data sheets and safety data sheets are available for our grades on request, and our team can advise on starting formulations, storage and handling for international shipments.

Technical Q&A

Frequently Asked Questions on Epoxy Resin Applications

Authoritative technical insights directly from our chemical synthesis laboratories, guiding formulators, chemical buyers, and processing engineers.

How do modified epoxy acrylates prevent curing brittleness compared to standard Bisphenol-A epoxy resins?

Standard Bisphenol-A (DGEBA) epoxy acrylates exhibit exceptionally high crosslinking density and rigid aromatic backbones, resulting in pencil hardness up to 3H–4H but limited flexibility (<5% elongation). To resolve brittleness, Ever Ray chemically modifies the molecular backbone by incorporating aliphatic flexibilizing segments, polycaprolactone extenders, or soft polyester segments between the bisphenol cores and the acrylate functionalities. This decreases volumetric shrinkage stress during free-radical polymerization, preserves high conversion rates, and imparts critical impact resistance without compromising hardness.

What are the optimal photoinitiator combinations for curing epoxy resins under 395nm UV-LED lamps?

Legacy curing utilized short-wavelength Type I cleavage initiators (like 1173 or 184) under broad-spectrum mercury lamps. For 395nm UV-LED sources, these standard photoinitiators lack photon absorption. Formulators must employ long-wavelength phosphine oxide initiators (such as TPO, TPO-L, or BAPO/819). However, because surface curing at longer wavelengths suffers from oxygen inhibition, adding reactive amine synergists (such as Ever Ray amino acrylates or active amine co-initiators) is essential. The amine groups rapidly abstract hydrogen, creating initiating alpha-amino radicals and consuming quenching oxygen molecules at the coating interface.

Can UV-curable epoxy resins achieve boiling-water resistance on glass and metal surfaces?

Yes, but it requires addressing interfacial moisture displacement. Direct acrylate adhesion onto smooth, non-polar, or hydrophilic surfaces like glass and untreated metals often deteriorates under boiling water exposure due to hydrolytic cleavage of hydrogen bonds. By blending specialized adhesion-promoting functional oligomers containing phosphate esters or alcoxysilane pendant groups (e.g., our special functional series), chemical covalent bonds (Si-O-Si or Metal-O-P) form with the inorganic substrate, guaranteeing crosslink durability under severe boiling water and thermal immersion tests.

How does batch-to-batch viscosity variance impact high-speed offset and flexo printing applications?

In modern offset and flexo packaging lines running at high speeds, even a 5% shift in oligomer viscosity alters ink transfer, emulsification balance, dot gain, and blade wiping behavior. Ever Ray’s automated DCS synthesis controls reactor temperatures within ±0.5°C and monitors reactant dosing gravimetrically, maintaining oligomer viscosity within a strict ±3% specification. This tight manufacturing tolerance prevents misting, maintains water-ink balance, and eliminates machine downtime for ink formulators.

What documentation and international compliance certifications accompany bulk chemical exports?

All export consignments from Ever Ray include batch-specific Certificates of Analysis (COA), comprehensive Technical Data Sheets (TDS), and globally compliant Safety Data Sheets (GHS/CLP formatted SDS in English and multiple destination languages). Our products adhere strictly to REACH (SVHC compliance), RoHS 3, and TSCA inventory listings, supported by rigorous third-party lab testing for heavy metal, phthalate, and halogen restrictions.
