Featured UV Curable Resins & Precision Formulations
Select high-purity polyurethane acrylates, polyester acrylates, and specialty oligomers synthesized for industrial coating, printing ink, and additive manufacturing lines.
Molecular Chemistry of UV Polyurethane Acrylates (PUA)
UV-curable polyurethane acrylates (PUA) represent the pinnacle of high-durability polymer architecture in radiation curing technology. By synthesizing precise diisocyanates, polyol macrodiols, and hydroxy-functional acrylates, our chemists tailor crosslink density, mechanical elasticity, and chemical resistance.
Aliphatic PUA Oligomers
Synthesized with cycloaliphatic or linear aliphatic isocyanates such as IPDI (Isophorone Diisocyanate) and H12MDI. These backbones eliminate aromatic light-absorbing chromophores, delivering exceptional non-yellowing weatherability (ΔYI < 1.0 after 1,000h QUV).
Essential for optical-grade display films, consumer electronics (3C clearcoats), exterior architectural coatings, and cosmetic UV nail formulations.
Aromatic PUA Oligomers
Built utilizing TDI or MDI platforms to offer unmatched urethane intermolecular hydrogen bonding. This results in high tensile strength, supreme Taber abrasion resistance, and fast radical polymerization rates at optimized cost.
The gold standard for heavy-duty industrial parquet, vinyl composite tile (VCT), high-speed flexographic inks, and indoor pigmented industrial primers.
Waterborne PUA Dispersions
Eco-engineered polyurethane acrylates dispersed in aqueous media via internal ionic emulsifiers (DMPA). Eliminates reactive diluent skin irritation while matching 100% solids performance after physical water flash-off and UV crosslinking.
Delivers zero VOC compliance, ultra-thin dry film thickness (5–15 μm), and deep pore wetting on luxury wood, natural leather, and heat-sensitive film substrates.

| Difunctional Aliphatic PUA | Flexible / Elastic | ΔYI < 0.8 (Excellent) | 18 – 30 MPa | 80% – 180% | Thermoformable PC films, Optical LOCA, Flexible Inks |
| Hexafunctional Aliphatic PUA | Ultra-Hard (3H–5H) | ΔYI < 1.2 (Superior) | 45 – 65 MPa | 2% – 8% | 3C Electronic Shells, Anti-Scratch Automotive Clearcoats |
| Aromatic Urethane Acrylate | High Impact / Rigid | ΔYI > 4.0 (Moderate) | 35 – 55 MPa | 10% – 35% | Industrial Parquet Flooring, Heavy Machinery Primers |
| Hyperbranched PUA Resin | Balanced / Dense | ΔYI < 1.5 (High) | 50 – 70 MPa | 5% – 15% | Low-Shrinkage Micro-Optics, Fast-Cure 3D Resins |
