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.

Primary Formulation Solutions

High-Efficiency Reactive UV Acrylate Oligomers

Targeting critical curing dynamics, surface wetting balance, and extreme environmental durability across precision industrial substrates.

Engineering White Paper

Acrylate Oligomer Structural Chemistry & Future Technology Roadmap

Radiation-curable formulations rely entirely on oligomer backbone architecture to define fundamental mechanical modulus, glass transition temperature (Tg), chemical resistance, and crosslinking density.

Epoxy Acrylate (EA) Systems

Formed by reacting acrylic acid with bisphenol-A or novolac diglycidyl ethers. Delivers the industry's highest radical curing velocity, extreme hardness (up to 4H-5H pencil hardness), and exceptional chemical/solvent resistance.

Ideal for rapid sanding wood sealers and fast OPV
High modulus prevents post-cure mechanical micro-creeping
Modified grades mitigate inherent crosslinking brittleness

Polyurethane Acrylate (PUA) Series

Synthesized via aliphatic or aromatic diisocyanates (IPDI, HDI, TDI) reacted with polyols and hydroxyacrylates. Combines rigid urethane hard segments with elastic soft segments for extreme elongation and impact resilience.

Aliphatic PUA: Optical non-yellowing (>1000h QUV test)
Aromatic PUA: Cost-efficient heavy-duty floor wear coats
Controls substrate cure shrinkage to < 4.5%

Polyester & Hyperbranched Acrylates

Multi-ester backbone structures that deliver supreme pigment wetting properties and Newtonian-like rheology. Hyperbranched dendritic architectures provide 6-to-16 functionality with remarkably low viscosity.

Exceptional ink transfer and offset water-ink balance
High chemical dilution tolerance without radical quenching
Immediate oxygen-barrier skin formation during radiation

Our acrylate oligomer architectures address real-world conversion challenges: solving interface peeling on low-surface-energy polymers, micro-shrinkage curl, and high-speed oxygen inhibition.

3C Electronics & Consumer Optics

Thin coatings on polycarbonate (PC), ABS, and PMMA demand high surface hardness coupled with internal flexibility to pass thermal drop tests and alcohol wipe resistance (500g, >200 cycles).

Recommended Solution: Aliphatic Polyurethane Acrylates blended with Hyperbranched Oligomers ensures scratch resistance (>3H) with no substrate warping or optical haze.

Procurement & Engineering Inquiries

Frequently Asked Technical & Purchasing Questions

Expert insights directly from our chemical synthesis engineering team and international logistics department.

How do you optimize acrylate oligomers for LED-UV vs. Mercury Arc curing?

LED-UV lamps (365nm, 385nm, 395nm) emit narrow wavelength bands without deep-penetrating shortwave UVC (200-280nm). We counteract resulting surface tack by synthesizing low viscosity amino-modified polyester/polyurethane acrylates. The built-in tertiary amine acts as an internal hydrogen donor, quenching atmospheric oxygen inhibition at the air-coating interface.

What is the minimum order quantity (MOQ) and sample lead time?

Standard laboratory evaluation samples (500g to 2kg) ship internationally within 48 to 72 hours via air courier accompanied by analytical CoAs. For commercial bulk orders, standard drum MOQs are 200kg (single drum) or 1000kg (IBC tote), with tailored bulk synthesis programs accommodating containerload (FCL) delivery cycles.

How does Ever Ray prevent dark polymerization during container transit?

Acrylate oligomers are stabilized with specialized radical scavengers (such as MEHQ/BHT) calibrated to inhibit premature crosslinking while preserving full UV sensitivity. Packages are filled under precision dry-air cushions (never pure nitrogen, as phenolic stabilizers require dissolved oxygen to function) ensuring 12-month shelf life stability.

Can you adjust backbone functionality to improve flexible adhesion on untreated PET or PP?

Yes. Untreated plastic substrates have surface energies below 38 dynes/cm. We engineer pure acrylic or phosphate/carboxyl-modified functional oligomers that reduce internal film shrinkage below 3%, while introducing active polar anchorage sites that generate chemical bonds with polyolefin and polyester surfaces.
