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.

Expert Inquiries & Answers

Essential guidance on formulation, system handling, and material performance from our technical department.

What core differences separate Aliphatic from Aromatic Polyurethane Dispersions?

Aliphatic grades utilize raw materials like IPDI or H12MDI, delivering exceptional resistance to sunlight, yellowing, and weather exposure—ideal for outdoor applications and clear topcoats. Aromatic variants (based on TDI or MDI) provide higher hardness and cost efficiency, suited for indoor primers, sealers, and pigmented wood layers.

How does waterborne UV resin address flash-off and curing?

Waterborne UV oligomers require an initial heat-assisted flash-off zone to evaporate water from the film prior to radiation curing. Once dry, exposure to standard mercury or LED-UV light triggers radical polymerization of acrylic double bonds, achieving instantaneous film crosslinking and mechanical strength.

Can you provide customized viscosity and solids configurations?

Yes. Our synthesis lines can adjust molecular weight distribution, counter-ion neutralization, and particle size to fit spray, roller, curtain, or gravure coating processes, maintaining stability across varying shear rates.

What measures guarantee stability across international freight routes?

Our aqueous dispersions feature freeze-thaw stabilizers and microbial defense packages. Shipments are packed in high-density polyethylene drums or IBC containers rated for multi-modal marine and overland transport with complete safety certifications.
