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

Frequently Asked Questions

In-depth technical answers addressing vacuum metallization formulation, adhesion integrity, and bulk supply protocols.

Why is low outgassing critical for UV vacuum plating basecoats?

Under high vacuum chambers (≤10⁻³ Pa), unreacted low-molecular monomers, trapped solvents, or moisture volatilize rapidly. This causes severe vacuum pump oil contamination, extended pump-down cycles, and creates microscopic vapor clouds that destabilize the plasma stream, leading to pinholes, haze, and flaking in the aluminum or chromium layer.

How does Ever Ray resolve "rainbow lines" or iridescence in UV topcoats?

Iridescent interference patterns happen when the cured topcoat's refractive index diverges significantly from the thin sputtered metal layer or varies due to phase separation. Our custom functional acrylate formulations maintain controlled optical homogeneity, leveling uniformly at 10-15 μm without regional crosslink density gradients.

What is the typical shelf life and recommended storage for these oligomers?

Stored in original sealed drums away from direct heat, sunlight, and UV sources at temperatures between 15°C and 28°C, Ever Ray UV resins have a certified shelf life of 12 months. All batches include specialized radical scavengers (MEHQ/BHT) calibrated to avoid auto-polymerization during maritime transit.

Can you provide custom modifications for challenging substrates like untreated PP?

Yes. Untreated polypropylene (PP) possesses very low surface energy (typically ~29-31 dynes/cm). We synthesize chlorinated or polar-grafted functional acrylate oligomers that drastically enhance mechanical interlocking and thermodynamic wetting without requiring flame or plasma pre-treatments.
